Bilz-counterbore A-HSS
- Particularly suitable for spotfacing and counterboring of screw head counterbores in tough steel- , aluminium- and copper-alloys up to about 800 N/mm²
- Three respectively four cutting edges (D>=18) with rake angle 25° respectively 30° offer high stock removal rates at low cutting forces
- Long tool life due to multiple regrindability
- Universally usable on many kinds of machine tools with and without rotating pilot
Bilz-counterbore variation 3-HSS:
- for hardened tough and brittle materials (Rm > 800 N/mm²)
- rake angle γ= 18°
Bilz-counterbore A-HM
- For hard and tough, brittle and short-chipping materials like grey cast iron, brass and aluminium
- Three cutting edges with rake angle 8° respectively 12° (D>=9)
- Fine-grain carbide with high wear resistance
- Long tool life due to multiple regrindability
- Universally usable on many kinds of machine tools with and without rotating pilot
Bilz-counterbore AW
- Particularly suitable for spotfacing and counterboring of screw head counterbores in all kind of material
- Three insert seats for carbide-, cermet- and HSS-E-Inserts with different geometries and coatings
- Round ground guiding chamfers on the inserts (...Z...) prevent chattering, burnish the bore surface and allow close tolerances (IT9-11)
- Universally usable on many kinds of machine tools with and without rotating pilot
