3M 7100037245 Non-woven Buff Blend Disc 7 Inch Ao

Product Description

The 3M 7100037245 is a non-woven nylon abrasive disc designed for light deburring, surface cleaning, and final finishing on metal workpieces. Built with high-strength nylon construction, the disc resists tearing and fraying during edgework and contact with irregular surfaces. At 7 inches in diameter with a 1/2 inch arbor, it mounts to standard angle grinders and disc sanders used in metal fabrication, finishing shops, and maintenance environments. The Aluminum Oxide mineral delivers a consistent scratch pattern across ferrous and non-ferrous metals, making it a reliable choice for technicians who need repeatable surface prep results without gouging the base material.

This disc is suited for professional use in metal fabrication, HVAC sheet metal work, plumbing rough-in finishing, and general industrial maintenance where controlled surface conditioning is required. The open web structure resists loading, reducing debris buildup that shortens abrasive life. It is available in three grades to match the job: Coarse for aggressive material removal, Medium for general conditioning, and Very Fine for final finishing or polishing passes. Technicians working on both ferrous and non-ferrous substrates will find this disc performs consistently across material types without smearing or contaminating the surface.

Key Features

• High-strength non-woven nylon resists tearing and fraying during edgework and irregular surface contact
• Dense, stiff construction holds up under high pressure without folding, supporting consistent productivity
• Aluminum Oxide mineral cuts cleanly and produces a uniform, smear-free scratch pattern on ferrous and non-ferrous metals
• Open web design is load resistant, limiting debris buildup and extending disc service life
• Available in Coarse, Medium, and Very Fine grades for varying degrees of aggressiveness and final finish
• 7 inch diameter with 1/2 inch arbor fits standard disc grinders and finishing tools

Compatibility

Designed for use with standard angle grinders and disc finishing tools accepting a 7 inch disc with a 1/2 inch arbor hole. Suitable for ferrous and non-ferrous metal substrates in fabrication, maintenance, and surface conditioning applications.

Installation Notes

Mounting and use of abrasive discs should be performed by qualified personnel familiar with angle grinder and disc sander safety practices. Verify the tool's maximum RPM rating meets or exceeds the disc's rated speed before mounting. Ensure the arbor nut is properly secured before operation, and always use appropriate personal protective equipment including eye and face protection. Inspect the disc for damage before each use and remove from service if tearing or fraying is observed.
