3M 7000045171 Quick-change Disc 1.5 in 60 Grit Ceramic Roloc Tr

Product Description

The 3M 7000045171 is a ceramic-abrasive quick-change disc designed for high-speed material removal on metal and other hard surfaces. It mounts to Roloc TR and Type R attachment systems, making tool changes fast without requiring additional hardware. At 60 grit, it falls in the medium grade range — aggressive enough for weld blending, surface prep, and deburring while leaving a workable finish. The polyester cloth backing rated YF weight provides flexibility and durability under load. Maximum operating speed is 30,000 RPM. The disc measures 1.5 inches in diameter and is sold individually with a minimum order quantity of 50 units.

This disc suits metal fabrication, maintenance, and surface preparation tasks in industrial, commercial, and trade settings. Typical applications include weld seam blending, rust removal, edge deburring, and paint or coating removal on steel and similar substrates. The Roloc TR quick-change design is widely used with angle grinders and die grinders equipped with compatible Type R mandrels. The 984F series ceramic grain is self-sharpening under pressure, making it efficient for sustained grinding operations.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and disconnected from its power source. Verify the mandrel and grinder are rated for the 30,000 RPM maximum speed of this disc before use. Always inspect the disc for damage before mounting and wear appropriate PPE including eye protection and gloves. Follow ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
