3M 7010309372 Quick-change Disc 3 in Aluminum Oxide Coarse

Product Description

The 3M 7010309372 is a Roloc TS quick-change abrasive disc designed for surface preparation, blending, and finishing applications in metal fabrication and maintenance work. Built with aluminum oxide abrasive in a non-woven construction, it delivers consistent cut and surface texture on ferrous and non-ferrous metals. The disc measures 3 inches in diameter and operates at a maximum rated speed of 18,000 RPM. It attaches via a Type S quick-change button system, allowing fast disc swaps without tools. The coarse grade makes it well suited for aggressive material removal, rust cleanup, and weld seam blending. Licensed tradespeople and fabricators in HVAC, plumbing, and general metal trades use this disc regularly in production and field service environments.

This disc is used in angle grinder and die grinder applications where rapid disc changes and consistent abrasive performance are required. Typical install scenarios include ductwork fabrication, pipe fitting preparation, structural steel cleanup, and surface conditioning prior to welding or coating. The non-woven aluminum oxide construction conforms moderately to contoured surfaces, making it useful for working around fittings and irregular geometry. It is sold individually as a single disc per package.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and disconnected from its power source.

Wear appropriate PPE including face shield and gloves during operation, and follow applicable ANSI B11 and OSHA abrasive wheel standards. Do not exceed the disc maximum RPM rating under any operating condition.
