3M 7010308509 Hookita 236U Disc 5 Inch P320 Grit Ao

Product Description

The 3M 7010308509 is a coated abrasive disc in the Hookita 236U series, designed for high-production sanding operations across industrial and trade environments. Built on a C-weight paper backing with premium aluminum oxide mineral and an open-coat, load-resistant construction, this 5-inch disc delivers fast cutting action and extended abrasive life. The Hookita attachment system allows quick disc changes and reuse throughout the disc's service life. It is well suited for finishing work on paint, primer, wood, metal, plastic, and composite materials including fiberglass.

This disc is intended for use in industrial production sanding as well as general-purpose surface preparation and finishing applications. The P320 grit rating makes it appropriate for fine sanding passes, paint prep, sealer scuffing, and smoothing composite substrates. It is commonly used in automotive body, woodworking, and light fabrication environments where consistent scratch patterns and surface finish quality are required. Installers and technicians working with orbital or random-orbit sanders will find the Hookita hook-and-loop style attachment straightforward to work with.

Key Features

• Premium aluminum oxide mineral cuts fast and holds up across multiple surface types
• C-weight paper backing provides durability for aggressive sanding compared to lighter paper grades
• Open-coat construction resists loading and extends disc life in high-production use
• Load-resistant coating helps maintain cut rate over the full life of the disc
• Hookita attachment system allows fast disc changes and supports disc reuse
• Rated to 12,000 RPM for compatibility with standard random-orbit and disc sanders

Compatibility

Designed for use with Hookita-compatible 5-inch disc sanders and random-orbit sanders that accept hook-and-loop style backing pads.

Installation Notes

Verify that the sander backing pad is clean and free of debris before attaching the disc to ensure full contact and secure hold. Do not exceed the 12,000 RPM maximum speed rating. Inspect the disc before each use and replace if mineral is worn, the backing is torn, or the attachment surface is compromised. Appropriate eye protection and dust collection should be used in accordance with applicable safety standards.
