Mechanical Tooling Wear-grade material
Mechanical-Grade Diamond
For cutting edges and wear surfaces where mechanical duty drives the choice of diamond.

Good to know
- Mechanical grade describes the duty rather than a universal quality rank.
- Wear resistance, edge integrity and workpiece compatibility need to be considered together.
- Optical or electronic grade requirements should not be assumed.
