- Regular Blocky Crystal Shape: Provides stable grinding behavior with consistent contact area.
- Partial Sharp-Edged Particles: Enhances initial cutting efficiency during grinding.
- Low Strength: Allows easy micro-fracture for continuous edge renewal.
- Good Friability: Supports self-sharpening and stable grinding performance under light load conditions.
Wheel Grit Diamond – GWD815
20+ Years Experience
Ultra-Precision Quality
Customized Solutions
GWD815 is a wheel grit diamond developed for low-load grinding applications that require sharp cutting edges and controlled self-sharpening behavior. With a blocky crystal structure and good friability, this grade is suitable for vitrified bond tools used in edge grinding and precision grinding of brittle, non-metallic materials.
