For extreme hard- ness at the tip of the tooth (up to 68 HRC). A high wear resistance and lifetime. Only a few manufacturers are ca- pable of producing step-hardened annular cutters. For Karnasch this is 'standard'. We produce extremely hard tooth tips (68 HRC) and yet a flexible annular cutter. Our first-class annular cutters are equipped with the unique and patented DURABLUE-coating. Extreme surface hardness and sleekness yield extreme lifetimes even under non-optimum con- ditions like 'overhead work', dry drilling, etc. PROPERTIES APPLICATION Steel Steel Alu Alu Steel Stainless Stainless Copper, brass, tin Plastics GRP/CRP Grey cast iron Hastelloy, Inconel, Nimonic, exotic materials Carbide tipped annular cutters and coated HSS-XE cutters provide the optimal price-performance ratio. The Karnasch DURABLUE-coating makes the annular cutter decisively more resistant. This results in a considerable increase of product life. BLUE-DRILL LINE annular cutters are the most commonly used Karnasch cutters. These HSS-XE cutters offers the best price-performance ratio for all steels up to a strength of 40 Rockwell (HRC) and stainless steels. Hardox 400 Hardox 450 Completely made 'FULLY GROUND'. This refining increases the cutting ability while reducing friction at the same time. For an extended lifetime. OPTIMAL GOOD POSSIBLE BLUE-DRILL LINE 11 Index 10 9 OIL 8 7 6 5 4 3 2 1
