3M 7100264090 Quick-change Disc 2in Ceramic Non-woven Coarse

Product Description

The 3M 7100264090 is a 2-inch diameter quick-change abrasive disc designed for use with Roloc TR Type R attachment systems. Built with a ceramic, non-woven construction and rated at a coarse grade, this disc delivers aggressive surface conditioning on metal and other hard substrates. It is part of 3M's PN-DR series and carries a maximum operating speed of 25,000 RPM. The brown non-woven web structure allows for consistent cut and finish throughout the disc's life, making it a reliable choice for deburring, blending, and surface prep work. Tradespeople in fabrication, HVAC sheet metal, and maintenance applications rely on this disc for repeatable results on angle grinders and die grinders equipped with a Type R mandrel.

This disc is suited for light to moderate material removal and surface conditioning tasks in both residential and commercial trade settings. Typical applications include weld blending, rust and scale removal, edge deburring, and pre-paint surface preparation on ferrous and non-ferrous metals. The Type R quick-change system allows for fast disc swaps without tools, reducing downtime during production or field service work. The coarse ceramic abrasive provides a faster cut rate compared to aluminum oxide alternatives, making it appropriate for heavier conditioning tasks where speed matters.

Installation Notes

Installation and use of this disc should be performed by qualified tradespeople familiar with abrasive tool safety. Always verify that the grinder's rated speed meets or exceeds the disc's 25,000 RPM maximum before mounting. Inspect the disc for damage before each use and never operate a damaged or delaminated abrasive disc. Follow applicable ANSI B7 abrasive safety standards and wear appropriate PPE including eye and face protection during operation.
