applications
High-performance drill for the drilling of long and short-chipping materials such as structural and case hardened steels, cast steels, heat-treatable steels and alloyed steels with a tensile strength of up to 1000 N/mm˛, including carbon steels, cast iron and high- alloyed AlSi-alloys.
This tool is also available TiAIN- and TiCN-coated, for performance increase in special operations.
Recoating is recommended when regrinding. TiCN-tools can be recoated with TiN (S-coat).
