3M 7000120238 Psa Cloth Disc 777F 12 Inch 60 Grit

Product Description

The 3M 7000120238 is a 12-inch PSA cloth disc in the 777F series, designed for moderate stock removal through finishing on metal workpieces. It uses a ceramic aluminum oxide grain blend that delivers higher cut rates and longer service life compared to standard aluminum oxide abrasives. A built-in grinding aid manages heat buildup during aggressive grinding, making this disc well-suited for demanding applications on both ferrous and non-ferrous metals. The pressure-sensitive adhesive backing bonds securely to a backup pad and releases cleanly at the end of the job. Rated at a maximum of 2000 RPM, it is intended for use with compatible disc grinders and sanders.

This disc is used in metal fabrication, weld blending, and surface conditioning operations across industrial and shop environments. The heavyweight cloth backing handles high-pressure passes without breaking down, which is why it sees regular use on stainless steel, carbon steel, and non-ferrous alloys. It is equally applicable in production grinding scenarios and in finishing work where a controlled cut rate is required. Licensed tradespeople and skilled fabricators working with large-diameter grinders will find this disc a reliable fit for demanding material removal tasks.

Key Features

• Ceramic aluminum oxide grain blend for superior cut rate and durability over standard aluminum oxide
• Pressure-sensitive adhesive backing adheres firmly to backup pad and removes cleanly
• Heavyweight cloth backing withstands high-pressure grinding applications
• Integrated grinding aid reduces heat buildup when working exotic metals such as stainless steel
• Suitable for both ferrous and non-ferrous metal surfaces

Compatibility

Designed as an OEM-style PSA disc replacement for use with backup pads and disc grinders that accept 12-inch pressure-sensitive adhesive abrasive discs.

Installation Notes

Disc mounting and operation should be performed by qualified personnel familiar with abrasive grinding equipment and applicable ANSI B11 safety standards. Ensure the grinder is fully powered off and unplugged before mounting or removing the disc. Confirm the backup pad is clean and free of debris before pressing the PSA disc into place to ensure full adhesion. Never exceed the rated maximum speed of 2000 RPM.
