Vitrified Bond - Silicon Carbide, Hardness Grade R
Hardness grade R mounted points are made of grey silicon carbide in a vitrified bond. These products are noted for their hardness and durability.
- Hardness grade R tools are ideally suited for heavy-duty edge grinding on castings. They are distinguished by their high edge-holding capability, long service life and low wear.
- Due to their special edge-holding properties, hardness grade R mounted points can also be used economically with low RPM power tools.
In edge grinding operations, hardness grade R mounted points perform best at a recommended peripheral speed of 6,000 - 9,800 SFPM. For surface grinding we recommend a peripheral speed of 4,000 - 6,000 SFPM. Suitable drive systems include flexible shafts and electric or air-powered straight grinders.
