3M 7100046324 Abrasive Film Disc 120 Grit 6 Inch

Product Description

The 3M 7100046324 is a coated abrasive film disc engineered for aggressive stock removal on a wide range of substrates. It uses 3M Precision Shaped Ceramic Grain, a triangular mineral that slices through material rather than plowing across it. This geometry results in faster cut rates and extended disc life compared to conventional abrasive designs. The film backing adds tear resistance and holds the disc edge intact during use. At 6 inches in diameter with a 120-grit cut, this disc suits finishing and aggressive blending operations where consistent material removal is the priority. It mounts via hook and loop attachment for quick changeouts in production or field settings.

This disc is built for stock removal applications across metal fabrication, bodywork, and general surface preparation tasks. The hook and loop interface works with standard 6-inch random orbital and right-angle disc sanders equipped with compatible hook-face backup pads. Its film backing performs well on both flat and slightly contoured surfaces, holding up to edge pressure better than paper-backed alternatives. The 120-grit rating positions it as a mid-range cut for removing weld scale, blending transitions, or prepping surfaces before finer finishing steps.

Key Features

• 3M Precision Shaped Ceramic Grain slices substrate rather than gouging, cutting up to 2x faster than conventional abrasives
• Extended disc life — engineered to outlast conventional abrasive discs by up to 6x
• Film backing provides greater tear resistance and edge retention versus paper-backed discs
• Hook and loop attachment allows fast disc swaps without tools
• Suited for stock removal across a wide variety of substrates and applications

Compatibility

Designed for use with 6-inch hook-face backup pads on random orbital and right-angle disc sanders compatible with hook and loop abrasive discs.

Installation Notes

Attach the disc firmly to a clean, debris-free hook-face backup pad before operating the tool. Inspect the backup pad regularly — a worn or damaged pad reduces disc adhesion and can cause the disc to release during use. Follow the sander manufacturer's maximum RPM rating and do not exceed it with this disc. Wear appropriate eye protection and respiratory protection when grinding or sanding.
