3M 7010365075 Quick-change Disc 60 Grit Diamond 3 in

Product Description

The 3M 7010365075 is a coated abrasive quick-change disc designed for use with Roloc TR (Type III) attaching systems. The disc measures 3 inches in diameter and features a diamond abrasive at 60 grit, grade M250, bonded to a flexible polyester (J-weight) backing. It is rated for a maximum speed of 20,000 RPM. This disc suits metal fabrication, weld blending, surface conditioning, and precision stock removal tasks. It is installed and used by machinists, metal fabricators, and maintenance technicians working with angle grinders or die grinders equipped with a Roloc TR mandrel.

This disc is suited for applications requiring aggressive material removal on hard surfaces including steel, stainless steel, and other metals. The flexible polyester backing conforms to contoured workpiece geometry, making it effective for both flat and curved surface work. The TR quick-change mount allows rapid disc swaps without tools, reducing downtime during production or repair operations. Typical use scenarios include weld seam blending, surface preparation before coating, and deburring in light industrial and maintenance environments.
