CNC Collets: Types and Maintenance Tips

Anatomy of a collet

If you are from the manufacturing or construction industries, the term “collets” is probably familiar to you. There are many types of collets used in many different industries and applications. For this article, we shall focus on collets used in rotary tool holders typically found in CNC machining (milling) centers.

Before we get into the nuances of collets, it is vital to understand how collets work, what impacts their performance, how to maintain collets for long service life, and how to recognize when to replace them.

What are Collets?

Collets are the critical connection between the cutting tool and the tool holder (also called a collet chuck). Most collets are round, cone-shaped, and slotted. Collets encircle the cutting tool shank to evenly distribute holding power around its center bore.

As we continue to explain more about collets, it will first be helpful to understand the basic anatomy of collets and of a collet chuck system. The illustrations below will help provide a general understanding of the parts of a collet and collet chuck system.

Anatomy of a collet

anatomy of collet chuck system

 

 

How Collets Work?

The tapered collet base is made to fit into the collet pocket of the collet chuck body. The tapered design of the collet base and collet pocket allows the collet to be centered in the pocket as it is pushed in by the collet nut during setup. This centering effect enables the collet to achieve a high degree of accuracy (concentricity); much more than drill chucks and side-lock style holders.

As the collet is pushed into the pocket by the collet nut, the slots in the collet allow the I.D. bore to collapse and apply clamping pressure to the cutting tool shank. The result is a very strong and rigid clamping force on the cutting tool. Since the collet base is tapered to match the collet pocket, tool runout (T.I.R.) is reduced.

 

What are the different types of collets?

Collets come in many different types and sizes. Here is an overview of three of the more popular types of collets, along with the pros and cons of each system.

 

Double-Angle (DA) Collets

Double-Angle (DA) Collets

Double-Angle (DA) collets have been around for a long time and continue to be used in the market. There are, however, many issues associated with DA collets of which users should be aware.

One of the primary issues with DA collets is that they essentially clamp on the cutting tool shank with only two opposing faces in the I.D. bore. DA collets have four slots in the front of the collet and four slots in the back of the collet creating four clamping faces. However, when DA collets are tightened towards the lower end of their collapse range, two of the faces tend to be pushed out of the way so only two of the faces are clamping on the cutting tool shank. This may cause some runout at the nose when the tool is inspected in a presetter.

Additionally, when the tool begins cutting and side forces are applied to the cutting tool, the cutting tool tends to deflect into the area where the faces are not clamping on the tool shank. This results in excessive chatter that dramatically reduces tool life and results in rough surface finishes. You will be hard-pressed to find a quality end mill holder manufacturer endorsing the performance of their tooling in DA collets.

 

TG Collets

TG Collets

TG collets have about the same accuracy as DA collets, but because there are more slots, and therefore more faces clamping on the cutting tool shank, they tend to deliver greater holding power. TG can be a good solution for larger shank diameter cutting tools, but they generally limit how far down into a pocket you can reach due to interference with the collet nut, as TG collet nuts tend to be quite large.

TG collets are not as popular as ER collets for several reasons. Most notably, the larger diameter collet nuts can require the use of extended end mills to avoid interference from the collet nut when milling pockets. Also, since TG collets have a very small collapse range, they are intended for use with one size cutting tool shank. ER collets, by contrast, offer a large collapse range that can be helpful when clamping odd-shank diameter tools.

On the flip side, TG collets tend to have a bit more holding power than ER collets due to the collet base having a 4° taper as opposed to the 8° taper found in ER collets. This can make TG collets a good choice when machining with longer-length cutting tools.

 

ER Collets

ER Collets

The ER collet system has become very popular due to the flexibility of the system to hold a variety of cutting tool shank types including drills, end mills, and taps. Also, ER collets provide several solutions for increasingly popular coolant-through cutting tools.

Most standard ER collets have between a 0.020” and 0.040” holding range, making them a good choice when needing to hold odd-sized cutting tool shanks. This holding range also means fewer ER collets are required to hold a range of cutting tool shank diameters as opposed to other collet systems like TG.

The popularity of the ER collet system has led to several variations to hold a wide assortment of cutting tool shanks. Some ER collets have been modified with squares at the bottom to hold taps. Others have been modified to provide quick-change capabilities or compensation (also called “float”) for rigid tapping cycles as shown in the images below.

Tap collets

Other modifications include special slotting designs that seal around the cutting tool shank and force coolant through channels in coolant-through tooling, as well as modifications to include coolant ports in the collet that direct coolant to the cutting area.

Collet Maintenance Tips

Collets are a high-precision wear component of a tool holding system and require maintenance to ensure accuracy. First, it’s important to remember that collets are the softest component in a collet-based tool-holding system assembly and are designed to wear out.

Here is an overview of the wear pattern of a collet-based tool-holding system. The machine spindle is harder than the tool holder (a.k.a. collet chuck) that fits into the spindle, so any wear between these two components will mostly occur to the collet chuck. That’s good, as it protects the spindle from expensive maintenance. Collets are softer than both the collet chuck body and the cutting tool, so any wear forces between these items will mostly occur to the collet. Since collets are generally the least expensive component in a collet chuck tool holding system, it is preferred that the collets wear out before the other components.

Worn-out collets will not achieve the same level of accuracy and rigidity that newer collets can provide. The result is more chatter when cutting workpieces, less accuracy, and shorter cutting tool life. A good rule of thumb is to replace collets every 4-6 months to maximize the performance of your tooling. Again, collets are designed to wear out and are generally the least expensive component in the system. It is much less expensive to replace the collets as opposed to prematurely wearing out cutting tools.

The following tips will help you in maintaining collets:

  • Clean the collet with a cloth and the interior with a little brass brush (sometimes the broken ends of tools & other debris can become lodged within).
  • WD40 should be sprayed on fresh collets before being cleaned with a cloth. By doing this, the protective coating applied to collets before they are packaged will be removed (something that can make it harder to grip tools).
  • Ensure that there is no debris in the slots as this could reduce the clamping force. If an obstruction is seen in a slot, use a thin object, like a knife’s tip, to remove the obstruction.

 

 

Wrapping Up

Given the wide range of benefits offered by collets, they are one of the most indispensable tools in the manufacturing industry. To get the most from your collet-based tooling system, it is important to use best-in-class products to produce top-notch quality.

Frequently Asked Questions (FAQs)

1. How do I know when to replace collets?

Collets are designed to wear out as they lose accuracy and rigidity with use. High side-load forces during milling operations cause cutting tool deflection as illustrated below.

replace collets status

Over time, these side-load forces will bell-mouth the collet at its face.

Bell mouthing collet experiences

As the collet experiences bell-mouthing, the cutting tool is allowed to deflect more and more during milling operations. Unfortunately, the collet may still indicate good accuracy on a presetter where there are no side-load forces. However, once the tool is put into service and begins experiencing side-load forces, the cutting tool is allowed more room to deflect, resulting in increased chatter and reduced tool life.

It is recommended to change collets out every 4-6 months, depending on usage, to ensure the most rigid and accurate collet chuck assembly.

2. Are there other signs that a collet should be replaced?

Yes. Any signs of fretting on the collet indicate the collet is vibrating in the tool holder. Fretting appears as rust-colored spots typically at the highest point where the collet sits in the collet pocket of the collet chuck.

science of replace collets

This is not rust but rather an indication that there is a vibration between the collet and the collet pocket connection. The vibration causing the fretting is also reducing cutting tool life. If you see signs of fretting on the collet, it is advised to replace the collet. You should also ensure that collet nuts are tightened to the correct torque specifications during setup.

 

3. What is the correct method to assemble a collet and collet nut?

It is critical to properly assemble the collet and collet nut to avoid damage to the collet and make the most accurate and rigid assembly possible. The extraction groove of the collet must be properly seated to the extraction ring of the collet nut.

First, angle the collet so the extraction groove seats with the eccentric extraction ring in the collet nut as shown below.

extraction collet groove

Next, while holding the collet and nut together, place the assembly in the tool holder and begin tightening the nut. If the collet extraction groove is not properly seated to the collet nut extraction ring, the collet will appear seated below the face of the nut. This typically occurs when the collet is placed in the collet pocket of the tool holder and then the nut is threaded on the tool holder. In a correct assembly, the collet will seat at the face of the collet nut. The image below shows a correct assembly on the left and an incorrect assembly on the right.

correct method to assemble collet nut

DO NOT tighten the collet nut if the collet appears seated below the face of the nut as this will create galling on the 30° face of the collet. Galling appear as grooves or lines in the lead face of the collet.

collet galling on the 30° face

Galling on the lead face of the collet can result in reduced clamping pressure on the cutting tool shank that may lead to the cutting tool slipping while cutting, or even tool breakage.

When trying to ensure the most rigid and accurate collet chuck assembly, don’t take chances.

When in doubt, throw it out!

Remember, the collet is designed to wear out and is the least expensive component in a collet chuck system.

Why A Coated ER Collet?

Parlec PRO ER Collet

Special Anti-friction Coated ER Collet

It’s been estimated that a tool with a run-out of 50% of the tool’s chip load will reduce its tool-life by 40%.

That means that a 1/8” tool with a 0.00019” chip load per tooth will lose 40% of its tool-life with a run-out of less than 0.0001”.

Excessive and inconsistent run-out from a properly setup ER collet chuck assembly typically occurs due to friction build-up between the 30° face of the collet and the collet nut.

ER Collet Chuck - Area of Friction

As the collet nut presses down and turns against the 30° face of the collet, the collet face will tend to twist with the collet nut, distorting the shape of the collet. This radial distortion negatively affects tool run-out sine the collet bore is not longer straight.

 

ER Collet Angle Taper

Parlec’s new  P3 ER collets have a special anti-friction coating on the 30° face that dramatically reduces friction at this critical connection.

The result?

  • Improved tool runout
  • Longer tool-life
  • Less frequent tool changes
  • Improved surface finishes

Other Parlec P3 collet advantages:

  • 3 micron T.I.R
  • Fewer slots that standard collets making them more rigid – in the cut!
  • Special slotting seal for coolant up to 2,000 PSI

Improving The Accuracy and Holding Power of ER Collets

Improve Accuracy and Holding Power

ER Collet System - Small Collet Nut Holder

The ER collet system is a tried-and-true tool holding system used by just about every machine shop. Customers like the ability to meet almost any job from drilling to milling to tapping and the flexibility to hold a variety of shank diameters by just changing the bore size of the collet. However, achieving optimal clamping pressure and repeatable accuracy are challenges that have resulted in some “creative solutions”. We’ve seen it all. From cheater bars to provide additional torque on the collet nuts to tapping tool shanks for better accuracy.

In this article we will dissect what’s going on with the ER collet system that creates these challenges and why these “creative solutions” actually work against improving holding power and accuracy. Finally, we will explore the unique solutions Techniks Tool Group has develop to counter the shortcomings of ER collet system including the revolutionary new Parlec P3 collets.

Setup Time

We’ve all seen it. It’s time to setup an ER collet chuck and out comes the cheater bar to tighten the collet nut. Why do shops feel the need to use cheater bars to adequately tighten collet nuts? Well, no one wants to under tighten a collet nut for fear of the cutting tool coming loose during operation potentially requiring re-work, producing scrap, or worse, creating a serious safety issue. But, as we shall see, cheater bars can actually negatively affect clamping pressure and accuracy.

ER Collet Chuck Setup

Cheater Bars: Who Needs Them? NOBODY!

Friction Section of ER Collet

Cheater bars are an attempt to overcome one of the largest challenges of the ER collet system – friction. Friction robs the ER collet system of clamping pressure and can create inconsistent run-out of the cutting tool. Friction occurs between all mating surfaces of the ER tool holder assembly, most notably between the threads of the collet nut and the tool holder and between the collet nut and the 30° face of the collet.

Let’s first look at the friction between the threads of the collet nut and the tool holder. The threaded areas of the collet nut and the tool holder create a lot of contact surface area. As a collet nut is tightened on the tool holder the ground threads of the nut and the ground threads of the tool holder produce a great amount of friction.

When using a torque wrench, the buildup of friction between the threads will cause the torque wrench to indicate the proper torque value has been achieved. However, the actual torque being transferred to the cutting tool shank in the form of clamping pressure may be far less than anticipated or required for optimal holding power.

To see a demonstration of how the friction robs the ER collet chuck assembly of holding power, click here.

Crack in Collet Pocket

Torque Wrenches – The First Line of Defense

Shops have been using the extra leverage cheater bars provide to overcome the friction buildup between the nut and holder threads in order to increase the clamping pressure on the cutting tool. However, there is no control over how much torque is actually being produced. Without control, there can be no consistency.

In fact, cheater bars often result in too much torque that can create a host of issues like cracked collet pockets in the holders, cracked collets, and inconsistent run-out.

The first line of defense to ensure proper torque and setup of an ER collet chuck is a torque wrench. Torque wrenches are the “great equalizers”. Everyone, regardless of strength or size, can achieve the same torque on the collet nut with repeatable results. Shops looking to improve consistency should throw away their cheater bars and incorporate torque wrenches in their ER tooling setup.

Adjustable Torque Wrench Tool

Back to the Threads

To overcome the challenges of friction buildup between the threads of the collet nut and the threads of the tool holder, Techniks Tool Group developed our exclusive “Power-Coat” collet nuts. Power-Coat collet nuts have a special anti-friction coating that drastically reduce the friction between the threaded connection as well as the at the 30° face of the collet.

Difference Between Un-coated & Power-coat Collet Nuts

This permanent anti-friction coating helps Power-Coat ER collet nuts to achieve about 75% greater clamping pressure on the tool shank at the same torque specification as a standard, uncoated collet nut. No cheater bar required! Power-coat nuts come standard on all our Parlec and Techniks ER collet chucks.

Collet Nut Holding Power Testing

Consistent Accuracy, The Elusive Goal

In addition to optimal clamping pressure, shops often struggle with achieving consistent accuracy from their ER tooling. It seems that one setup will produce good accuracy, while just loosening and retightening the collet nut will result in poor accuracy. To correct this, some operators tap the cutting tool shank until the desired accuracy is achieved. What’s going on?

As the collet nut and collet assembly is being threaded onto the tool holder the collet will generally rotate with the collet nut. As the 8° taper of the collet mates with the collet pocket, it will stop rotating with the collet nut. You can rotate the nut back-and-forth and the collet will stay stationary.

 

ER Collets Accuracy

However, the collet nut must be further tightened to achieve the proper torque specification. As the collet nut continues to rotate, friction builds-up between the now stationary 30° collet face and the collet nut. This friction twists the top of the collet, causing radial distortion.

Think of having your feet buried while someone is turning your shoulders. Eventually, your spine will twist and break. Ouch! This radial distortion produces uneven clamping pressure around the tool shank reduces clamping pressure and creates accuracy issues.

To correct for poor accuracy, some operators will tap the tool shank to bring it into the desired accuracy. However, just tapping the tool shank into tolerance does not solve for the uneven clamping pressure resulting from twisting the top of the collet.  Once the machining starts, the tool shank will find its point of lowest energy and will, once again, move out of tolerance.

 

In order to achieve consistent accuracy, the friction between the 30° collet face and the collet nut must be reduced. Here, again, the Power-Coat collet nut helps overcome this challenge. Power-Coat collet nuts have the anti-friction coating on the mating surface with the 30° collet face. This greatly reduces the friction between the 30° collet face and the collet nut, so the radial distortion is reduced providing improved and consistent accuracy.


Parlec New P3 ER Collet System

Introducing the P3 ER Collet System – The ER Collet System, EVOLVED!

Pro P3 ER Collet - Special Anti-friction Coating

To further improve the holding power and accuracy of the ER collet system, Techniks Tool Group has developed the world’s first coated ER collet system – the P3 ER collet system. P3 (Parlec Pro Precision) has a special anti-friction coating on the 30° collet face. This anti-friction coating enhances the results of the Power-Coat collet nuts to further reduce friction buildup between the 30° collet face and the collet nut reducing radial distortion. Also, P3 ER collets have a reduced number of slots making the collets more rigid and further reducing radial distortion.

The result? Improved clamping pressure on the tool shank and improved accuracy. No tapping required!

For Ultimate Accuracy, Go ERos!

The ERos ER System

ERos Collet Nut

For the ultimate in accuracy, Parlec offers the ERos ER system. ERos collet chucks (ERos = ER on-size) are proudly Made-in-the-USA and feature several design improvements that enhance the performance you can expect an ER tooling setup.

ERos chucks and nuts have two pilots to more concentrically align the nut on the holder further improving accuracy. ERos collet nuts do not have any slots, reducing wind vibration at high spindle speeds. Also, the ERos collet nuts have a concentric extraction ring to remove the collet from the holder creating a superior balanced assembly. While the ERos system will improve the performance of standard ER collets, when combined with P3 collets, the ERos system produces results that some of our customers say exceeds that of shrink fit or hydraulic chucks.

Shops considering other tooling technologies to improve consistent accuracy and holding power shouldn’t abandon their investment in ER collet chucks and give the Power-Coat collet nuts and P3 ER collet system a try. Want the ultimate in accuracy and holding power? Try out the ERos collet system and P3 collets.

These are just a few of the technologies Techniks Tool Group has developed to overcome some of the challenges of the ER collet system and achieve superior results.

Best ER Coolant Collets

Techniks ER Coolant Collets


Machinists often are often challenged with the need to direct coolant to the cutting area. Getting coolant to the cutting area is critical for efficient chip evacuation, adding lubricity to the cutting surface, and cooling the cutting tool to avoid unnecessary heat build-up that can lead to premature failure. Flood coolant works well for surface cutting applications like face milling, but things are a bit more tricky when machining cavities or tapping as the workpiece can obstruct flood coolant. For these reasons, Techniks has developed a broad assortment of ER coolant collets to meet virtually any cutting application.


What is a Coolant Collet?

Coolant Collet Diagram

Coolant Collets get their name because they seal the cutting tool shank to direct coolant through the cutting tool. Coolant-through tooling is growing in popularity because of its effectiveness at clearing chips from the cutting area and permitting faster feeds and speeds. Coolant-through tools, such as end mills and drills, have coolant ports built into the tool shanks directing coolant at the cutting area, regardless of the depth of the hole or cavity. For proper performance and to avoid leaking and pressure loss, coolant collets are used to seal around the cutting tool shank prohibiting coolant from leaking through the slots in the collets and forcing the coolant through the cutting tool. This creates maximum coolant pressure at the cutting area which pushes chips away from the cutting path enhancing cutting performance and improving tool life.


What Options are Available for Coolant Collets?

Steel Sealed Coolant Collet

 

Steel Sealed Coolant Collet

Techniks offers several options for coolant collets. Our Steel-Sealed Coolant Collets have become a popular choice when using high-pressure coolant. Steel-Sealed Collets have a special slotting design that prevents coolant from reaching the collet face. Since the design of the slots prevent coolant leakage, these collets can be used in high-pressure coolant applications. Techniks Steel-Sealed Coolant Collets are pressure rated to 2,000 PSI. An important consideration for choosing the correct collet bore size is that Steel-Sealed Coolant Collets are intended for on-size use, meaning they are intended for use with a specific shank diameter.

Plug style coolant collet

 

Plug-Style Coolant Collet

In addition to Steel-Sealed Coolant Collets, Techniks also offers plug-style coolant collets. Plug-style Coolant Collets,  referred to as Coolant Collets, use rubber plugs in the slots to block coolant from leaking through the collet face. Most collet manufactures simply plug their standard collets in face slots to make coolant collets. Since standard ER collets have 16 slots (8 in the face and 8 in the back) these plugs can be rather small and can be blown out if coolant pressure exceeds their recommended value. In addition, the collapse range of standard collets, typically 0.040”, can cause plugs to be dislodged when used towards the bottom of the collapse range of the collet.

 

By contrast, Techniks Coolant Collets feature only 4 slots in the face. This permits larger plugs that can withstand higher coolant pressure more reliably. Techniks Coolant Collets are pressure rated to 750 PSI and have a 0.020” collapse range to avoid dislodging the plugs when clamping odd sized shanks.


What About Coolant-Through Taps?

ER steel sealed rigid tap collets

 

ER Steel Sealed Rigid Tap Collet

Coolant-through taps are growing in popularity for the same reasons as coolant-through drills and end mills – they allow for superior chip evacuation. Tapping blind holes leaves very little room to evacuate chips. Therefore, coolant directed at the start of the tap help drive chips up the tap flutes and out the hole producing better thread quality and helping extend tap life.

To meet the growing need to machine with coolant-through taps, Techniks provides our ER Steel Sealed Rigid Tap Collets. These tap collets feature a unique slotting design that engages the square of the tap shank to positively lock the tap and also seal around the tap shank to direct coolant through the tap. Steel Sealed Rigid Tap Collets are available for inch and metric taps in ER16, 20, 25, 32, and 40 sizes.


ER steel sealed collets with CoolBLAST ports

 

ER Steel Sealed Collet with CoolBLAST Ports

What if My Tooling is Not Coolant-Through?

As good as coolant-through tooling is at helping direct coolant to the cutting area, there are instances when standard solid-shank tooling is the preferred option. For one, coolant-through tooling typically costs more than its solid-shank counterpart so changing to coolant-through tooling can be a costly endeavor. Also, very small tool shanks may not have the clearance to bore coolant ports, or a particular tool has already been spec’d into a job. For these instances Techniks offers our ER Steel Sealed Collets with CoolBLAST. CoolBLAST is a feature where coolant ports are drilled into the collet face. Coolant is sealed at the tool shank. The angled CoolBLAST ports direct the coolant to the cutting area. Steel Sealed Coolant Collets with CoolBLAST have a pressure rating of 1,400 PSI.


PowerCOAT nuts have 75% more holding power than standard nuts

Don’t Forget the Collet Nut!

Coolant collets are generally more rigid and less collapsible than standard collets. Therefore, it is important to choose the right collet nut to ensure proper clamping pressure on the tool shank. Techniks PowerCOAT collet nuts feature an anti-friction coating that provides up to 75% greater clamping pressure than standard uncoated collet nuts. Uncoated collet nuts may not provide enough clamping power to ensure proper clamping pressure allowing the tool to slip while machining. Techniks PowerCOAT nuts are guaranteed to perform with our coolant collet options.

Techniks has a broad selection of ER Coolant Collets
