3M 7100202878 Sanding Disc 220 Grit 5 Inch 10 Pack

Product Description

The 3M 7100202878 is a 220-grit abrasive sanding disc engineered for fine finishing and between-coat sanding work. At 5 inches in diameter, it mounts to random orbital sanders via a hook-and-loop backing system that allows fast tool-free disc swaps on the job. The disc uses 3M premium mineral abrasive technology to deliver a combination of fast cut rate and extended service life. A patented universal hole pattern supports efficient dust extraction on both 5-hole and 8-hole random orbital sanders, keeping airborne particulate low and the work surface visible. Each pack contains 10 discs. The clog-resistant construction helps maintain consistent cut performance across the life of the disc.

This disc is suited for finish sanding on wood, plastic, and metal surfaces. At 220 grit, it is well-matched to between-coat prep work in painting and finishing applications, light stock removal on plastic trim, and final-pass smoothing on wood. Typical users include carpenters, painters, woodworkers, and general contractors working on residential construction, cabinetry, and surface prep for topcoats. The disc performs on flat panels, furniture components, and similar workpieces where a fine, consistent scratch pattern is required before final finishing.

Compatibility

Designed for use with 5-inch random orbital sanders equipped with either 5-hole or 8-hole hook-and-loop sanding pads.

Installation Notes

Installation and disc swaps should be performed with the sander unplugged or the battery pack removed. Align the disc holes with the sander pad holes before pressing the hook-and-loop surfaces together to seat the disc fully. Inspect the sander pad for worn hook material before installing a new disc, as a degraded pad reduces holding force during operation. Dust extraction equipment and appropriate respiratory protection are recommended when sanding in enclosed spaces.
