Why do I use them?
The continual fracture rate of ceramic grains prolongs consistent performance and maintains sharp cutting points throughout product life, easily penetrating harder materials. The continual sharpening effect avoids dulling and glazing, both of which will cause overheating and premature wear.
Ceramic grains produce high stock removal rates on most materials, but added pressure is necessary for proper use. Softer materials do not provide enough resistance against the grains and will likely glaze. Or, an operator may combat the reduced fracture rate by overapplying pressure, resulting in unnecessary fatigue for both operator and product.
