3M 7000028341 Hook and Loop Disc 5 Inch P400 Grit

Product Description

The 3M 7000028341 is a coated abrasive hook-and-loop disc designed for fine finishing work on a random orbital sander. Built on a lightweight A-weight paper backing with aluminum oxide mineral, this 5-inch disc operates at up to 12,000 RPM and is sized for standard 5-inch hook-and-loop sanding pads. The open-coat construction and load-resistant coating work together to reduce disc loading, maintain cut rate, and extend disc life. At P400 grit, it is engineered for final-stage surface prep and smoothing. HVAC fabricators, auto refinish techs, woodworkers, and general trades use this disc where a clean, swirl-minimized finish is required.

This disc is suited for finishing applications across a wide range of substrates including wood, primer, paint, sealers, topcoats, fiberglass, and plastics. It is a practical choice for contractors and technicians who need a fast-loading disc change during high-volume finishing runs. The hook-and-loop attachment system allows the disc to be removed and reattached multiple times, making it reusable across a work session without loss of holding strength.
