Karnasch Professional Tools annular cutter of high-alloy HSS-XE special steel combine innovative stage hardening and optimised blade geometries for the best combination of service life and machining output. Only very few manufacturers are able to produce annular cutter hardened in steps. This achieves best hardness of 68 HRC at the tooth tips with a still-flexible annular cutter. The patented Durablue-coating increases the service life again by the extremely increased surface hardness, even at high temperatures and without cooling.
For extremely difficult-to-machine materials, such as Hardox, Titanium, Inconell and rail steel, we recommend the use of the enormously wear-proof ASP-powder-steel drill � another highlight of the Karnasch product family for the most demanding of tasks.
The consistent improvement of each detail will warrant the usual high-end quality of our HSS-XE annular cutter in future as well.
