3M 7100078156 Hook Loop Sanding Disc 180 Grit 6 in

Product Description

The 3M 7100078156 is a 6-inch hook and loop sanding disc designed for surface preparation, finish sanding, and stock removal on wood, paint, and similar materials. Built on a C-weight paper backing with a coated aluminum oxide abrasive, this disc delivers consistent 180-grit cutting action across the full disc face. The gold-colored abrasive layer resists loading on softer materials, making it well-suited for finish passes where swirl marks and surface uniformity matter. Vacuum holes are included to support dust extraction, keeping the work surface clear and extending disc life. At 0.02 pounds, the disc is lightweight and attaches securely to any standard hook and loop random orbital or disc sander pad.

This disc is intended for use in woodworking, cabinet making, auto body preparation, drywall finishing, and general surface blending applications. The 180-grit rating places it in the fine sanding range, appropriate for intermediate to final finish passes before staining, sealing, or painting. The flexible construction allows the disc to conform slightly to contoured surfaces, improving contact and finish consistency. It is part of the 3M 236U series and is sold individually.

Installation Notes

Align the vacuum holes on the disc with the ports on the sanding pad before pressing the hook and loop surfaces together to ensure proper dust extraction. Confirm the sander is powered off and unplugged before attaching or removing the disc. Do not exceed the maximum RPM rating of the tool in use. Inspect the disc before each use and discard if the abrasive layer shows signs of loading, tearing, or delamination.
