3M 7010328188 Psa Cloth Disc 777F 12 Inch 50 Grit

Product Description

The 3M 7010328188 is a pressure-sensitive adhesive (PSA) cloth disc in the 777F series, designed for moderate stock removal through finishing on metal workpieces. Built on a heavyweight cloth backing, this disc uses a ceramic aluminum oxide grain blend that delivers superior cut rate and durability compared to standard aluminum oxide abrasives. At 12 inches in diameter with a 50-grit rating and a maximum operating speed of 2000 RPM, it is suited for demanding metalworking operations. A built-in grinding aid helps manage heat during use on exotic metals, extending disc life and protecting workpiece integrity.

This disc is intended for use in industrial and fabrication environments where consistent stock removal and surface finishing on ferrous and non-ferrous metals are required. Typical applications include weld blending, deburring, and surface preparation on stainless steel, aluminum, and other metals. The PSA backing allows quick mounting to a compatible backup pad and clean removal without adhesive residue, supporting efficient disc changes in production settings. It is well-suited for use by metal fabricators, welders, and machinists who require a reliable, high-performance abrasive disc.

Key Features

• Pressure-sensitive adhesive backing mounts securely to backup pads and removes cleanly without residue
• Ceramic aluminum oxide grain blend provides higher cut rate and longer service life than standard aluminum oxide
• Heavyweight cloth backing supports high-pressure, aggressive grinding applications
• Grinding aid reduces heat buildup during use on stainless steel and other exotic metals
• Suitable for use on both ferrous and non-ferrous metals
• 50-grit rating covers moderate stock removal through surface finishing tasks

Compatibility

Designed for use with PSA-style backup pads compatible with 12-inch diameter abrasive discs rated for a minimum of 2000 RPM.

Installation Notes

This disc is installed by trade professionals and fabricators using standard PSA backup pad equipment. Before mounting or changing discs, ensure the grinder or disc machine is fully powered off and the disc has come to a complete stop. Verify that the backup pad RPM rating meets or exceeds the 2000 RPM maximum disc speed before operation. Do not exceed the rated speed, and inspect the disc for damage before each use.
