3M 7100010687 Hookita 236U Disc 5 Inch P240 Grit

Product Description

The 3M 7100010687 is a Hookita 236U coated abrasive disc designed for high-production sanding and general-purpose material removal. Built on a C-weight paper backing with a premium aluminum oxide mineral and an open-coat, load-resistant construction, this 5-inch disc delivers fast cut and extended abrasive life across a wide range of surfaces. Rated to 12,000 RPM, it attaches and releases quickly via the Hookita hook-and-loop style interface, making disc changes fast on the tool without interrupting workflow. Installers and fabricators in industrial, paint, body, and woodworking environments rely on it for consistent, repeatable results.

This disc is well suited for sanding paint, primer, wood, metal, plastic, and composites including fiberglass. At P240 grit, it is appropriate for fine stock removal, surface prep before finishing, and blending operations. The open-coat construction resists loading on soft materials such as paint and wood, extending usable disc life in high-throughput production environments. It is sold individually and intended for operations requiring consistent surface finishing across multiple substrate types.

Key Features

• Premium aluminum oxide mineral for fast cut and durability across multiple surfaces
• C-weight paper backing provides extra support for aggressive sanding passes
• Open-coat, load-resistant construction extends disc life on paint, wood, and soft composites
• Hookita hook-and-loop attachment allows quick disc changes and disc reuse

Compatibility

Designed for use with 5-inch Hookita-compatible sanding pads and backup pads on random orbital and disc sanders used in industrial, automotive refinishing, woodworking, and composite fabrication applications.

Installation Notes

This disc is installed and removed by hand using the Hookita hook-and-loop interface — no tools required for disc changes. Confirm the sander is powered off and unplugged before changing discs. Do not exceed the 12,000 RPM maximum speed rating. Inspect the disc and backup pad for damage before each use, and replace immediately if tears, delamination, or excessive loading are present.
