With special surface treatment GOLD-TECH + FULLY GROUND + special steel HSS-XE are ideal for drilling in steel up to a strength of 40 Rockwell (HRC) and even suitable for stainless steels. APPLICATION Steel Steel Alu Alu Steel Stainless Copper, brass, tin Plastics GRP/CRP Hardox 400 Hardox 450 OPTIMAL GOOD POSSIBLE The GOLD-DRILL LINE annular cutters are made of high-alloyed HSS-XE specialty steel, have extreme hardness at the tip of the tooth (up to 68 HRC) which guarantees high wear resistance and tool life. 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 still yield a flexible annular cutter. These annular cutters have a high tool life because of Karnasch's Gold-Tech surface treatment technology. PROPERTIES Completely made 'FULLY GROUND'. This refining increases the cutting ability while reducing friction at the same time for an extended tool life.
