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. (For holes up to IT9 accuracy)
- Shank support for optimum stability in operation.
Application:
For stationary and rotating use. For holes up to IT9 accuracy.
Note:
The insert screw must be replaced after every fifth change of cutter insert.
Further sizes up to ⌀ 50.99 mm available on request.
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.
