Art.-no. 13250080
Manufacturer article no. 10470826
EAN 4050293018530
Application
For producing metric threads on CNC machines in through holes and blind holes in the non-ferrous metals (short-chip) and cast iron material groups in series production.
Execution
- with reinforced shank, M3 and M4 without internal cooling
Advantage
- long service life and high degree of process reliability thanks to innovative cutting geometry for machining cast iron and short-chip non-ferrous metals
- optimum chip removal due to internal cooling
