Karnasch counterbores with specially developed cutting geometries

Karnasch Professional Tools counterbores are available in HSS-XE- and HSS-XE TITAN-TEC versions.

The HSS-XE counterbores are made of high quality special steel "XE" for significantly longer tool lives as compared to HSS steels. The TITAN-TEC coated counterbores also considerably increase tool lives, even during dry machining (without or with only minimal cooling).

Due to the wide range of counterbores, nearly all steels that are difficult to machine, such as stainless and acid-resistant stainless steels, non-ferrous and light metals, cast iron and many more, can be used.
