3M 7100045070 Hook Loop Disc 80 Grit 5 in Ceramic

Product Description

The 3M 7100045070 is a 5-inch ceramic abrasive disc designed for use with hook and loop backup pads on angle grinders and random orbital sanders. Part of the 3M 775L series, it features a coated ceramic abrasive in 80 grit, placing it in the medium grade range. Ceramic abrasive cuts faster and lasts longer than conventional aluminum oxide on demanding materials including stainless steel, hard alloys, and high-strength steel. This disc suits production grinding, weld blending, and surface prep tasks where consistent stock removal and extended disc life matter.

The 775L series is built for metal fabrication, structural steel work, and industrial maintenance environments. The 5-inch diameter fits standard 5-inch hook and loop backup pads widely used in metalworking and fabrication shops. The 80-grit medium grade balances aggressive material removal with a surface finish suitable for follow-on finishing steps. This disc is a practical choice for fabricators, pipefitters, ironworkers, and maintenance technicians who need reliable performance across repetitive grinding applications.

Key Features

• Ceramic abrasive for faster cut rate and longer service life compared to conventional abrasives
• 80 grit medium grade for effective stock removal and weld blending
• Coated construction for consistent, uniform abrasive surface
• 5-inch diameter fits standard hook and loop backup pads
• Part of the 3M 775L series for industrial grinding and surface preparation

Compatibility

Designed for use with 5-inch hook and loop backup pads on angle grinders and random orbital sanders used in metal fabrication and surface preparation applications.

Installation Notes

Install and remove only when the tool is powered off and disconnected from its power source. Verify the backup pad diameter and attachment system match the disc before use. Inspect the disc for damage before each use and do not use a disc that shows tears, cuts, or separation of the abrasive layer. Follow applicable ANSI B7 and tool manufacturer safety guidelines for abrasive disc operation.
