Description
Version:
With back stop screw. Shanks hard turned (smooth cutting action!). With RFID/Balluffchip bore.
Advantage:
The tool is firmly clamped at the side with the clamping screw and supported at the back with the back stop screw. Clamping free of play, giving low vibration running.
Application:
For clamping tools with parallel shank and whistle notch shanks (2°) to DIN 1835 E and DIN 6535 HE.
- The loss of length due to regrinding of the drill front can be corrected by axial length adjustment in the toolholder.
