MicroFLOAT Tap Holders

• Compensates for hard to start taps
• Great for high pressure coolant applications
• Decreases cost by increasing tap life, decreasing scrap, and reducing tap breakage




Techniks MicroFLOAT tap adapters feature 0.008" of compression for hard to start or sensitive taps, and 0.040" of tension (extension) to compensate for any inaccuracy in the machine, taps, or associated tooling and fixturing.

How it Works

This system works much like the other high quality quick change tap adapters in our catalog. To change taps, pull the outside sleeve away from the v-flange to release the tap adapter in the toolholder so it can be changed or extensions can be added.

1. Select the MicroFLOAT chuck required for your machine spindle.

2. Select the ER adapter size and number of extensions needed for your tapping application.

3. To change taps, pull the outside sleeve away from the v-flange to release the tap adapter in the toolholder so it can be changed or extensions added.

4. Start tapping at 100% of pitch feed. If issues occur, program 3–5% below the pitch feed. This will engage more tension to ensure the tap does not drag coming out.
