Applicable wherever a high wear resistance and lifetime are required. Only a few manufacturers are capable 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 DURABLUEcoating. Extreme surface hardness and sleekness yield extreme lifetimes even under non-optimum conditions like 'overhead work', dry drilling, etc. POWDER STEEL + DURABLUE-COATED ANNULAR CUTTERS Steel Steel Stainless Alu Copper, brass, tin Plastics GRP/CRP Grey cast iron Rails Hardox 400 Hardox 450 Hastelloy, Inconel, Nimonic, exotic materials APPLICATION Carbide tipped annular cutters and coated powder steel cutters provide an excellent 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 PRO annular cutters are the right choice for most difficult materials. Drilling in steel up to 45 Rockwell (HRC).
