3M 7010330825 Non-woven Abrasive Disc 3 Inch Ao

Product Description

The 3M 7010330825 is a non-woven nylon abrasive disc designed for light deburring, surface cleaning, and final finishing on metal workpieces. Built on a high-strength open-web construction, the disc maintains stiffness under pressure without folding, tearing, or fraying — making it reliable on irregular surfaces and tight edge work. The 3-inch diameter disc mounts via a 1/4-inch arbor hole and uses Aluminum Oxide mineral for consistent cut and scratch pattern across ferrous and non-ferrous metals. Machinists, fabricators, and surface finishing technicians are the primary installers and users of this disc.

This disc is suited for use on metal surfaces requiring light material removal and a uniform final finish. Typical applications include deburring machined parts, cleaning weld zones, and preparing surfaces prior to coating or inspection. The open-web structure resists loading, which extends service life compared to closed-coat alternatives. It is available in Coarse (CRS, green), Medium (MED, blue), and Very Fine (VFN, maroon) grades to match varying levels of aggressiveness and finish requirement.

Key Features

• High-strength non-woven nylon construction resists tearing and fraying during edgework
• Dense, stiff web withstands high pressure without folding, supporting consistent stock removal
• Aluminum Oxide mineral delivers a sharp, repeatable scratch pattern on ferrous and non-ferrous metals
• Open-web design is load-resistant, reducing debris buildup and extending disc life
• Produces a uniform, smear-free finish suitable for final finishing operations
• Available in three grades: Coarse, Medium, and Very Fine

Compatibility

Designed for use with angle grinders, die grinders, and bench-mounted arbor tools accepting a 1/4-inch arbor, for surface finishing and light deburring on ferrous and non-ferrous metal substrates.

Installation Notes

Installation and use of abrasive discs should be performed by personnel familiar with rotary abrasive tooling and applicable ANSI B7 safety standards. Ensure the tool is powered down and unplugged before mounting or removing the disc. Verify the tool RPM rating does not exceed the maximum rated speed of the disc. Eye protection and appropriate PPE are required during operation.
