- For maintenance and repair applications, from medium grinding to light deburring and finishing. Pressure-sensitive adhesive (PSA) offers fast, convenient disc mounting. Discs are made without center holes for full-face usage. 8" discs and smaller are designed for use on orbital sanders or vertical shaft grinders and must be used with PSA back-up pads; 5" and 6" pads are listed on page 1260, 3716. Discs 9" and larger are designed for use on stationary disc sanders.
- ARC - Zirconia Alumina
- Zirconia alumina grain is more durable and more aggressive than aluminum oxide and is particularly suited to mild steels. Zirconia grain continually fractures to expose new, sharp cutting surfaces that give a cleaner, cooler cut.
