3M 7100202873 Sanding Disc 120 Grit 5 Inch 10 Pack

Product Description

The 3M 7100202873 is a 5-inch hook-and-loop sanding disc designed for use with random orbital sanders on wood, plastic, and metal surfaces. Built around 3M premium mineral technology, this disc cuts fast and resists clogging to extend disc life across sanding sessions. The patented universal hole pattern supports efficient dust extraction on both 5-hole and 8-hole random orbital sanders, keeping the work surface visible and the jobsite cleaner. Each pack contains 10 discs at 120 grit, suited for smoothing surfaces and leveling between finish coats. Licensed HVAC technicians, finish carpenters, painters, and general tradespeople working on construction and renovation projects rely on this disc for consistent, repeatable results.

This disc is well-suited for residential and light commercial applications where surface prep is required across multiple material types. Typical use cases include smoothing wood prior to painting or staining, scuffing plastic components for adhesion, and deburring or finishing metal surfaces. The 120-grit rating places it in the medium range, making it a practical choice for the intermediate stages of a sanding progression. At 5 inches in diameter, it fits the standard pad size found on most random orbital sanders used in construction, woodworking, carpentry, and home improvement trades.

Installation Notes

Install and remove discs only when the sander is powered off and disconnected from its power source. Align the disc holes with the sander pad holes before pressing firmly to engage the hook-and-loop connection. Inspect the disc for wear or loading before each use and replace when cutting performance drops. Use of appropriate respiratory protection and dust collection is recommended when sanding wood, plastic, or metal.
