HiPer-Drill base body 36 mm

• 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.

For stationary and rotating use. For holes up to IT9 accuracy.

Further sizes up to ⌀ 50.99 mm available on request.
The insert screw must be replaced after every fifth change of cutter insert.
Reduce feed rates f by 10 % and v_c values by 40 %.
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.
