- Grade Introduction
- Polycrystaline Cutting Tools
- For Non-Ferrous Metals
 FOR NON-FERROUS METALS MD205 MD220 MD230 |
| Suitable for materials such as aluminium alloy, non-ferrous metals, and fiber reinforced plastic. |  |
| APPLICATION |
| Grade | Application |
| MD205 | Please use when there is insufficient resistance to wear with the MD220. |
| MD220 | For finishing non-ferrous metals (aluminium, copper
alloy). Applicable to non-metals (cemented carbide, semi-sintered ceramics, FRP, hard rubber, carbon, etc.). |
| MD230 | Please use when there is insufficient resistance to fracturing with MD220. Please use when performing interrupted cutting of a nonferrous metal, and you desire a high-quality finished surface. |
