3M 7100222628 Hook Loop Disc 80 Grit 5in Ceramic

Product Description

The 3M 7100222628 is a 5-inch hook and loop abrasive disc designed for aggressive material removal on metal, composites, and hard surfaces. Built on a YF-weight cloth backing, this disc delivers the rigidity needed for demanding grinding and blending tasks without sacrificing conformability on contoured workpieces. The ceramic abrasive grain is self-sharpening, which helps maintain consistent cut rate throughout the disc's service life. At 80 grit, it removes weld scale, rust, and surface defects efficiently before finishing steps. The hook and loop attachment system allows fast disc changes on compatible random orbital and disc sanders used by fabricators, pipefitters, and maintenance technicians.

This disc is suited for use in industrial fabrication, metal finishing, and maintenance environments. The 784F Series construction targets applications where heat buildup and disc glazing are common problems with conventional abrasives. Typical applications include weld blending on structural steel, surface prep before coating or priming, and stock removal on stainless and mild steel. The cloth backing handles moderate-to-high pressure grinding passes without tearing, making it a reliable choice for both shop use and field service work.

Key Features

• Ceramic abrasive grain provides self-sharpening cut for extended disc life
• YF-weight cloth backing supports firm pressure grinding without backing failure
• 80 grit removes weld scale, mill scale, rust, and surface defects in preparation for finishing
• Hook and loop attachment enables rapid disc swaps on compatible sanders
• 3M 784F Series construction resists heat buildup and glazing common in metal grinding
• 5-inch diameter fits standard random orbital disc sanders used across fabrication and maintenance trades

Compatibility

Designed for use with 5-inch hook and loop random orbital sanders and disc grinders that accept hook and loop abrasive discs. Verify backing pad diameter and attachment style before installation.

Installation Notes

Disc installation and replacement should be performed with the sander or grinder powered off and unplugged or locked out per applicable workplace safety procedures. Press the disc firmly onto the hook and loop backing pad to ensure full surface contact before operation. Inspect the backing pad regularly for worn or contaminated hook material, as a degraded pad reduces disc retention and can cause disc separation during use. Abrasive disc work on metal typically falls under general industry standards; follow applicable OSHA and ANSI B7-series guidelines for abrasive product use.
