3M 7010330821 Non-woven Buff Blend Hp Disc 3 Inch Ao

Product Description

The 3M 7010330821 is a non-woven abrasive disc designed for aggressive surface preparation tasks including deburring, light material removal, and contaminant stripping on metal substrates. Built with a high-performance (HP) non-woven construction, this disc is stiffer and more tear-resistant than standard GP-grade material, making it well-suited for edge work and demanding shop applications. The 3-inch diameter disc mounts on a 1/4-inch arbor and features aluminum oxide abrasive in a very fine (VFN) grade. Licensed HVAC techs, machinists, fabricators, and sheet metal workers reach for this disc when preparing ferrous and non-ferrous metal surfaces before finishing or assembly.

This disc is commonly used in light industrial, HVAC fabrication, and plumbing prep environments where burr removal and surface conditioning are routine steps. The open-web structure conforms to irregular surfaces without gouging the base material, allowing controlled stock removal along edges and contoured profiles. It is appropriate for use on steel, aluminum, copper, and other common trade metals encountered during installation and service work.

Key Features

• HP non-woven construction is stiffer and more tear-resistant than GP material, suited for edge deburring and metal removal
• Aluminum oxide abrasive delivers a sharp, consistent scratch pattern on ferrous and non-ferrous metals
• Pliable open web removes burrs and surface contaminants without gouging the substrate
• Load-resistant open web limits debris buildup that can clog the abrasive surface
• Very fine (VFN) grade aluminum oxide; red disc color indicates AO abrasive type
• 1/4-inch arbor mount for compatibility with standard right-angle and die grinders

Compatibility

Designed for use with rotary tools and grinders fitted with a 1/4-inch arbor. Suitable for deburring and surface conditioning on ferrous and non-ferrous metals including steel, aluminum, and copper.

Installation Notes

Mount the disc securely to the arbor before operation and confirm the tool RPM rating does not exceed the disc rating. Wear appropriate eye protection and gloves when operating abrasive discs. Inspect the disc for tears or damage before each use and replace if the non-woven web shows signs of deterioration. Follow shop safety protocols and applicable OSHA guidelines for abrasive wheel use.
