3M 7010308524 Psa Cloth Disc 777F 5 Inch 36 Grit

Product Description

The 3M 7010308524 is a PSA cloth disc in the 777F series, designed for moderate stock removal through finishing on metal workpieces. It measures 5 inches in diameter and runs a 36-grit ceramic aluminum oxide grain blend that outperforms standard aluminum oxide in both cut rate and durability. The pressure-sensitive adhesive backing mounts directly to a compatible backup pad without fasteners. This disc is rated to 10000 RPM and suits heavy-pressure grinding and finishing operations on ferrous and non-ferrous metals, including stainless steel and other exotic alloys.

This disc is used in metalworking and fabrication environments where consistent stock removal and surface finishing are required. The heavyweight cloth backing supports high-pressure applications typical of weld blending, deburring, and surface prep on sheet metal, structural steel, and stainless steel components. A built-in grinding aid helps manage heat at the surface when working exotic metals, reducing the risk of heat discoloration or workpiece damage during extended runs.

Key Features

• Pressure-sensitive adhesive backing sticks securely to backup pad and removes cleanly without residue
• Ceramic aluminum oxide grain blend delivers superior cut rate and longer service life versus standard aluminum oxide
• Heavyweight cloth backing handles high-pressure, demanding metalworking applications
• Grinding aid reduces running temperatures on exotic metals such as stainless steel
• Suitable for use on both ferrous and non-ferrous metals
• 5 inch diameter at 36 grit rated to 10000 RPM

Compatibility

Designed for use with PSA-style backup pads compatible with 5-inch disc configurations on angle grinders, disc sanders, and similar rotary tools rated at or above 10000 RPM.

Installation Notes

Metalworking professionals and fabricators install this disc by pressing the PSA backing firmly onto a clean, dry backup pad, ensuring full surface contact before operation. Verify that the tool and backup pad are both rated for 10000 RPM or higher before mounting. Power down and disconnect or lock out the tool before disc changes. Do not exceed the disc speed rating and inspect the disc for damage before each use.
