Description
Version:
- Very high feed rates and maximum performance due to optimally matched geometries and materials.
- Precise positioning of the cutter insert due to Vee insert seating and secure clamping by the centre bore.
- High concentricity when assembled.
- Shank support for optimum stability in operation.
Polished flutes.
Application:
For stationary and rotating use. For holes up to IT9 accuracy.
Note:
Further sizes up to ⌀ 50.99 mm available on request.
The insert screw must be replaced after every fifth change of cutter insert.
For process reliability when using the drill, initial pilot drilling to 1.5×D with the drill No. 231600 with the same cutter insert size and type is necessary. The generation of a pilot hole improves process reliability.
Clamp in a hydraulic chuck (such as No. 302026 size 20) for optimum radial run-out.
For optimum stability, clamp the drill so the overhang is as short as possible.
Reduce feed rates f by 10 % and vc values by 30 %.
