3M 7000045178 Quick-change Disc 2 in 80 Grit Ceramic Roloc Tsm

Product Description

The 3M 7000045178 is a coated abrasive quick-change disc designed for use with Roloc TSM Type S attachment systems. Part of the 3M 984F series, it features a ceramic abrasive grain bonded to a polyester cloth backing rated YF weight. The disc measures 2 inches in diameter and carries an 80-grit, medium-grade cut suitable for aggressive stock removal on metal surfaces. It is rated for a maximum speed of 25,000 RPM. The ceramic grain construction delivers consistent cut rate and cooler grinding temperatures compared to conventional aluminum oxide discs, making it a practical choice for surface prep, weld blending, and deburring in production and maintenance settings.

This disc is suited for metalworking applications in fabrication shops, maintenance facilities, and field service environments. The 2-inch diameter fits compact right-angle grinders and die grinders equipped with a Roloc TSM Type S mandrel. Typical use cases include weld seam blending, edge deburring, surface conditioning on ferrous and non-ferrous metals, and paint or rust removal. The coated construction resists loading, helping maintain cut efficiency across the life of the disc. It is sold individually with a minimum order quantity of 50 units per order.
