3M 7100089185 Hookit 401Q Abrasive Disc 2000 Grit 6 Inch

Product Description

The 3M 7100089185 is a Hookit 401Q coated abrasive disc designed for fine finishing on both wet and dry surfaces. Built on an A-weight waterproof paper backing, the disc uses silicon carbide mineral at 2000 grit to deliver a fast cut with a smooth, consistent finish. At 6 inches in diameter and rated to 12000 rpm, it is suited for hand sanding or machine use with compatible Hookit-style random orbital sanders. Licensed HVAC technicians, body shop professionals, and finishing tradespeople rely on this disc for final-stage surface prep on a range of substrates.

This disc is well-suited for wet or dry finishing applications on paint, primer, gel coat, metal, and wood. The waterproof backing reduces loading during wet sanding, extending disc life and improving cut rate. The 2000 grit rating makes it appropriate for final finishing passes where a refined surface texture is required before coating or inspection. It ships in quantities consistent with shop and production use.

Installation Notes

Attach the disc to a compatible Hookit backing pad by pressing firmly until the hook-and-loop connection is fully seated. Confirm the sander is powered off and unplugged before changing discs. When running wet, ensure water flow is controlled to avoid pooling near electrical components of the sander. Inspect the disc for tears or loading before each use and replace as needed.
