Properties and Application:

ER32 tapping collet dedicated to the stable clamping of M3 machine taps.
To ensure maximum tool safety and prevent breakage, it is recommended to use an ER32 tension-compression tapping chuck, which compensates for feed rate errors.
Our offer also includes sealed collets, essential for machining operations with high-pressure through-coolant.
