1" Roloc TR 777F Cloth Grindiing Disc - 80YF Grit

These discs combine the versatility of the Roloc attachment system with the premium performance of Regalite, this is 3M's trademark for their 700 Series abrasives - a blend of sharp cutting aluminum oxide and the especially durable Cubitron synthetic mineral abrasive.
Cubitron particles are somewhat less sharp than aluminum oxide, but they are harder and wear down more slowly. The blend results in a disc that provides faster cutting, more consistent scratch, and extended life compared to a traditional premium aluminum oxide disc. It is especially suitable for high heat applications such as working on tough metal substrates - like stainless steel or cold rolled steel.
• Excellent on stainless steel, aluminum, and fiberglass
• Also used on nickel alloys, titanium, and some carbon steel applications
• Grinding aid for less loading and cooler running
• Resin bonded for additional heat resistance
• Sold by the each
Use these discs with a Roloc Disc Pad to support the disc; see Related Products, below.
