3M 7100010692 Hookita 236U Disc 5 Inch P120 Grit Ao

Product Description

The 3M 7100010692 is a Hookita 236U coated abrasive disc designed for high-production sanding and general-purpose surface preparation. Built on a C-weight paper backing with premium aluminum oxide mineral, this 5-inch disc delivers aggressive cut and extended service life. The open coat construction and load-resistant coating keep the disc surface clear longer, maintaining consistent cut rates across a full range of substrates. It is rated for speeds up to 12,000 rpm and attaches via the Hookita hook-and-loop system for fast disc changes without tools. Typical installers and operators include fabricators, painters, body technicians, and finishing trades working in industrial and production environments.

This disc is suited for both high-production sanding operations and general-purpose finishing work. Compatible surfaces include paint, primer, bare wood, metal, plastic, and composites including fiberglass. The P120 grit designation places it in the fine range, making it appropriate for intermediate and finish sanding passes where surface profile control matters. It is sold individually and intended for use on random orbital and disc sanders equipped with Hookita-compatible backing pads.

Key Features

• Premium aluminum oxide mineral provides fast cut and durability across multiple surface types
• C-weight paper backing supports aggressive sanding with greater durability than lighter paper backings
• Open coat construction resists loading to extend abrasive life and maintain cut consistency
• Load-resistant coating further reduces premature disc fouling on paint, primer, and wood
• Hookita hook-and-loop attachment allows quick disc swaps and disc reuse
• Rated to 12,000 rpm for compatibility with standard production disc sanders

Compatibility

Designed for use on random orbital and disc sanders fitted with Hookita-compatible hook-and-loop backing pads. Suitable for sanding paint, primer, wood, metal, plastic, and composites including fiberglass.

Installation Notes

Mounting and disc changes should be performed with the sander powered off and unplugged or air supply disconnected. Verify the backing pad is clean and free of debris before attaching the disc to ensure full hook-and-loop engagement. Do not exceed the 12,000 rpm maximum speed rating. Inspect the disc before each use and discard if torn, perforated, or showing signs of delamination.
