3M 7000045175 Quick-change Disc 1-1/2 in 80 Grit Ceramic

Product Description

The 3M 7000045175 is a ceramic-abrasive quick-change disc designed for use with Roloc TR and Type R attachment systems. At 1-1/2 inches in diameter and rated at 80 grit (medium grade), this coated disc delivers consistent cut on metal deburring, weld blending, and surface prep applications. The polyester cloth backing with YF-weight construction supports aggressive stock removal without excessive loading. Ceramic abrasive grains self-sharpen during use, which extends disc life compared to aluminum oxide alternatives. Maximum operating speed is 30,000 RPM. This disc is sold individually with a minimum order quantity of 50 units.

This disc is suited for light fabrication, maintenance, and repair work involving ferrous and non-ferrous metals. Typical applications include weld seam blending, edge deburring, and surface conditioning on sheet metal and structural components. The Roloc TR quick-change system allows tool-free disc swaps on compatible angle grinders and die grinders, making it practical in production and field service environments where downtime between abrasive changes needs to stay short.

Installation Notes

Installation is performed by a machinist, fabricator, or maintenance technician using a compatible Roloc TR or Type R mandrel mounted in a die grinder or angle grinder. Verify the tool spindle speed does not exceed the disc maximum RPM rating before operation. Inspect the disc for damage before each use and discard any disc showing tears, delamination, or missing abrasive material. Always wear appropriate eye and face protection when operating rotary abrasive tools.
