DRAW-IN COLLETS

Schlenker draw-in collets are designed and manufactured to offer maximum precision and reliability.
By using them, you improve the processing quality and precision of your machines considerably.

USE OF DRAW-IN COLLETS

Draw-in collets are used for workpiece clamping as well as in all common grinding machines, dividing heads and manual turning machines.
Clamping is performed by retracting the draw-in collet into the collet sleeve.
