3M 7000028183 Quick-change Disc 2 in 24 Grit Aluminum Oxide

Product Description

The 3M 7000028183 is a Roloc TR quick-change abrasive disc designed for aggressive material removal in grinding and surface preparation applications. Built on a polyester cloth backing with YF backing weight, it uses aluminum oxide abrasive at 24 grit (very coarse grade) for fast stock removal on metals and other hard surfaces. The Type R attaching system allows tool-free disc changes on compatible right-angle grinders and die grinders. Rated at a maximum of 25,000 RPM, the disc is suited for high-speed work where downtime between disc swaps needs to stay minimal. It is 2 inches in diameter and brown in color, part of the 3M 361F series.

This disc fits residential maintenance, fabrication shops, and industrial service environments where rapid material removal or weld blending is required. The very coarse 24 grit is appropriate for removing heavy rust, scale, weld spatter, or paint from steel and other metal substrates. It is commonly used by metalworkers, pipefitters, HVAC sheet metal technicians, and maintenance mechanics working with angle grinders or die grinders equipped with a Type R or Roloc TR hub.
