3M 7100142280 Quick Change Abrasive Disc 2 in Coarse

Product Description

The 3M 7100142280 is a quick change surface conditioning disc designed for aggressive material removal on metal surfaces. Built with aluminum oxide abrasive on a non-woven XD substrate, it delivers high initial and extended cut rates on both flats and edges. The stiff resin bond holds the abrasive firmly, supporting consistent edge durability through demanding cycles. Licensed HVAC, plumbing, and metal fabrication tradespeople use this disc for deburring, blending, and surface prep prior to final coatings or finishes. At 2 inches in diameter, it fits standard quick change mandrel systems common in portable angle grinders and die grinders.

This disc is suited for use on ferrous metals, non-ferrous metals, stainless steel, and high nickel and chrome alloys. It performs best in applications where high contact pressure and aggressive stock removal are required before a final finish or coating is applied. The open web construction responds to surface irregularities, reducing the risk of gouging the workpiece. It is sold in a coarse grade in brown color, making it easy to identify in a mixed disc inventory on the job.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and unplugged or the air supply disconnected before mounting or removing the disc. Ensure the quick change mandrel is rated for the disc diameter and operating speed before use. Follow all applicable ANSI B7.1 grinding safety standards and wear appropriate PPE including face shield and gloves during operation.
