3M 7010364089 Quick Change Disc 50 Grit 3 Inch Ao

Product Description

The 3M 7010364089 is a coated quick change abrasive disc designed for paint removal, surface prep, and metal grinding in collision repair and fabrication work. Built around a 3-inch diameter format, this disc uses aluminum oxide abrasive at 50 grit for aggressive stock removal on metal surfaces. A heat-resistant resin bond maintains stability under the high temperatures generated during sustained grinding. The disc includes a built-in backing plate that provides rigid support and simplifies adapter attachment for fast disc swaps on handheld grinders. Automotive body technicians, metal fabricators, and collision repair professionals are the primary users of this disc.

This disc is suited for collision repair shops, metal fabrication, and general grinding applications where a compact 3-inch disc allows access to tight or contoured areas. The Kut-Down design means worn edges can be trimmed and the disc refreshed, extending usable life and reducing material waste. It is sold in box quantities with a minimum order of 4 units. The disc connects to handheld grinders via the Kut-Down Disc Adapter, 3-inch, part number 05533.
