Vitrified Bond - Aluminum Oxide, Hardness Grade O
Hardness grade O mounted points consist of pink aluminum oxide in a vitrified bond. Good edge holding and long service life characterize hardness grade O, making it predominant in its field of application.
Advantages:
- Hardness grade O tools are ideally suited for heavy-duty edge grinding on steels. They are noted for their high edge-holding and dimensional stability, long service life and low wear.
- Due to their special edge-holding properties, hardness grade O mounted points can also be used economically with low RPM power tools.
In edge grinding operations, hardness grade O mounted points perform best at a recommended peripheral speed of 5,000 - 7,800 SFPM. For surface grinding we recommend a peripheral speed of 3,000 - 5,000 SFPM. Suitable drive systems include flexible shafts and electric or air-powered straight grinders.
