Slim-Fit collets hold tighter than ER collets

How a Slim-Fit tool holder works



Torx Wrench
Actuates drawbar thru the pull stud for fast tool changes.
Drawbar
Holds collet or extension more tightly and more accurately than ER chucks.
Slim-Fit 20 Collets
Collets provide good rigidity, and the nut-less design allows a small nose for better clearance and is better balanced too.
Extensions
Additional reach when you need it and the nose O.D. of only .56" is great for tight clearance applications.
Slim-Fit 6 Collets
Same powerful drawbar holding power for improved accuracy and tool life.
