Description
Version:
- All shanks hard turned.
- Supplied with 4 table cooling channel bores.
Advantage:
- No risk of the cutter being pulled out, not even a tug.
- Optimised external contour − vibration-damping behaviour.
- Pleasant handling thanks to the differential thread.
- Breakage of the milling cutter shank is improbable.
- Precision version.
Application:
For clamping tools with side drive flats to DIN 1835 Form B and DIN 6535 Form HB. Best suited for TPC milling or high feed rate applications. No risk of the cutter being pulled out, more precise radial run-out, process reliability!
