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.
Application:
For stationary and rotating use. For holes up to IT9 accuracy.
Recommendation:
Drill the pilot hole.
Note:
Further sizes up to ⌀ 50.99 mm available on request.
The insert screw must be replaced after every fifth change of cutter insert.
reduce v
f values by 20 %.
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.
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.
