| 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 | |
