3M 7010329874 Hook Loop Abrasive Disc 5 in Very Fine

Product Description

The 3M 7010329874 is a 5-inch hook and loop non-woven abrasive disc designed for surface conditioning, light deburring, and finishing work on metal, wood, and composite surfaces. Built with aluminum oxide abrasive grain in a very fine grade, it cuts consistently without loading and leaves a uniform scratch pattern. The non-woven construction allows the disc to conform to contoured surfaces while maintaining controlled cut rates. It attaches and releases quickly via a hook and loop backing, making disc changes fast during production or field work. This disc is handled by metalworkers, fabricators, painters, and maintenance trades performing prep and finishing operations.

This disc is suited for surface preparation tasks such as blending welds, removing light oxidation, scuffing between finish coats, and conditioning metal prior to coating or plating. The very fine grade makes it appropriate for finish-stage work where scratch depth must be kept minimal. At a 5-inch diameter, it fits standard random orbital and right-angle sanders equipped with hook and loop backup pads. It is used in both shop and field environments across light manufacturing, metal fabrication, and general maintenance applications.

Key Features

• 5-inch diameter fits standard hook and loop random orbital and angle grinder backup pads
• Aluminum oxide abrasive provides consistent cut and long service life on metal and wood
• Very fine grade for finish-stage blending, scuffing, and surface conditioning
• Non-woven construction conforms to contours and reduces loading
• No vacuum holes — suited for tools without dust extraction ports
• Rated to 12,000 RPM maximum for safe use on common pneumatic and electric sanders

Compatibility

Designed for use with hook and loop backup pads on 5-inch random orbital sanders, right-angle grinders, and similar tools rated up to 12,000 RPM. Part of the 3M Series 7447 non-woven abrasive disc line.

Installation Notes

Confirm the backup pad is clean and free of debris before attaching the disc to ensure full hook engagement across the face. Do not exceed the rated maximum speed of 12,000 RPM. Inspect the disc for tears or delamination before each use and remove from service if damage is found. This consumable is replaced by peeling the disc from the backup pad — no tools required.
