Application
for cutting fit tolerances in through holes on modern CNC machines with steady tool and workpiece clamping, in stainless steel.
Execution
- 7–8° left-hand spiral, extremely variable pitch and inner cooling, type B
Advantage
- Innovative cutting geometry provides very high stability and process reliability, with very high cutting parameters
- High-quality solid carbide cutting material and coating ensure a very long service life
- Internal cooling ensures optimal transportation of chips
Notes
Make sure that tools are accurately and tightly clamped (ideally use a hydro-mechanical clamping chuck or precision collet chuck). When ordering, specify the desired fit and diameter (e.g. 8.05 H7) take care! Please refer to dimension table.
