BILZ piloted counterbore 180 degrees w. detachable pilot HSS T=3 size 02 7.0 mm
Brand: HERMANN BILZ
Length: 35 mm
Art.-no. 11540070
Manufacturer article no. A 070021
Application
For producing 180° counterbores in connection with interchangeable pilots in steel, (stainless steel), non-ferrous metals, (cast) and special alloy material groups up to a strength of 1000 N/mm² in single part production.
Execution
- profile-ground piloted counterbore with removable pilot with twisted cutting edge, with three cutting edges for diameters up to 17.5 mm, or four cutting edges as from 18.0 mm diameter
Advantage
- very positive chip angle ensures a very soft cut in long-chipping materials up to 1000 N/mm2 and minimises the cutting forces
- wide chip chambers for smooth chip removal
- innovative cutting geometry provides excellent cutting performance and good finish quality
