One tool for virtually all materials
Solid machining process for all application needs
- Short chips due to several chip breakers and an extremely precise twist angle to the geometry / a helix angle that is precisely adjusted to the tool geometry
- The extremely robust core ensures significantly reduced vibrations and reduces the risk of tool breakage considerably
Easy to use in almost all modern CNC production processes
Wide cutting value range
Long service life thanks to newly developed SUPRADUR coating
- Extremely resistant special coating for a wide range of applications
- Optimum resistance to temperature changes increases process reliability even under the toughest conditions
- Ideal for wet and dry processing in almost all materials
