Work Material Stainless steels Titanium alloys Plastics Non ferrous metals Corrosion and heat resistant steels Stainless steels Titanium alloys Non ferrous metals Corrosion and heat resistant steels Fibreglass-reinforced plastic Grey cast iron Carbon fibre-reinforeced materials Hardened steel Graphite composite materials Aluminium alloys Corrosion and heat resistant stells Stainless steels Titanium alloys Non ferrous matals Characters Extra fine grain hard metal for solid carbide rotary tools applications in the ISO K30-K40/C2-C3. Suit for most cuttings. Superior grain for solid carbide rotary tools applications in very wide range ISO K40 -K50 / C1-C2. Great for low and high speed milling and roughing work when milling and boring. High hardness and extreme bending strength, suit for the drilling of electronic boards and other fibreglass-reinforced plastics and milling of difficult materials. Murakami-Etching
