3M 7100010690 Hookit 236U Disc 5 Inch P180 Grit

Product Description

The 3M 7100010690 is a Hookit 236U coated abrasive disc designed for high-production sanding and general-purpose material removal. Built on a C-weight paper backing with premium aluminum oxide mineral, this 5-inch disc delivers aggressive cut and extended service life across a wide range of surfaces. The open-coat construction and load-resistant coating keep the disc surface clear during use, maintaining cut rate and prolonging abrasive life. It spins at a rated maximum of 12,000 RPM and is finished to a P180 grit. Installers and fabricators in industrial and finishing shops rely on this disc for consistent, repeatable results.

This disc is suited for sanding operations on paint, primer, wood, metal, plastic, and composites including fiberglass. It fits Hookit-compatible random orbital and disc sanders commonly used in automotive refinishing, woodworking, metal fabrication, and general industrial finishing. The 5-inch diameter and P180 grit make it a practical choice for finish-stage material removal where surface quality and cut control both matter.

Installation Notes

This disc is installed and removed by trade finishers, fabricators, and surface prep technicians using Hookit-compatible random orbital or disc sanders. Confirm the sander's maximum RPM rating meets or exceeds the disc's 12,000 RPM rating before use. Inspect the disc backing and Hookit attachment surface before each use and discard any disc showing tears, excessive wear, or delamination. Follow the sander manufacturer's guard and speed requirements when operating.
