3M 7100222757 Hook Loop Disc 5 Inch 120 Grit Ceramic

Product Description

The 3M 7100222757 is a 5-inch hook and loop abrasive disc designed for surface grinding, blending, and finishing applications in trade and industrial environments. Built on a YF-weight cloth backing, this disc uses a ceramic abrasive grain at 120 grit to deliver consistent stock removal and a controlled finish. The coated construction distributes abrasive material evenly across the disc face, supporting smooth, repeatable results through the life of the disc. It attaches via a hook and loop fastener system, allowing fast disc changes without tools. HVAC sheet metal fabricators, pipefitters, and general metalworkers are the primary users of this type of disc.

This disc suits applications requiring moderate-to-fine material removal on metal, stainless steel, and similar hard substrates. The 120-grit ceramic grain is appropriate for blending weld seams, deburring cut edges, and preparing surfaces before coating or inspection. The cloth backing provides flexibility for working on flat and slightly contoured surfaces. It is sold individually and is compatible with 5-inch hook and loop backing pads on right-angle grinders and random orbital sanders used in fabrication and field service work.

Key Features

• 5-inch diameter fits standard hook and loop backing pads on right-angle grinders and orbital sanders
• 120-grit ceramic abrasive grain for controlled stock removal and surface blending
• YF-weight cloth backing provides durability and moderate flexibility on flat and contoured surfaces
• Coated abrasive construction for even grain distribution across the disc face
• Tool-free disc changes via hook and loop attachment system
• 3M 784F series construction for consistent performance through the disc life

Compatibility

Designed for use with 5-inch hook and loop backing pads on right-angle grinders and random orbital sanders. Verify backing pad hook and loop interface before mounting.

Installation Notes

Installation is performed by pressing the disc firmly onto a clean, dry 5-inch hook and loop backing pad mounted on a grinder or sander. Inspect the backing pad for worn hooks before attaching a new disc, as a degraded pad reduces secure retention. Ensure the grinder or sander is powered off and unplugged before changing discs. Follow tool manufacturer RPM ratings and applicable ANSI B7 safety standards for abrasive disc use.
