Superior Abrasives A018189 Deburring Disc 1 Inch Fine

Product Description

The SUPERIOR ABRASIVES A018189 is a 1-inch diameter deburring disc designed for material finishing and edge deburring on metal workpieces. Built with an aluminum oxide abrasive in a fine grade, this disc mounts via a 1/8-inch shank and spins at up to 20,000 RPM. The maroon web construction provides controlled cut and surface contact, making it well suited for removing burrs, light flash, and sharp edges without aggressive stock removal. Machinists, fabricators, and tool-and-die technicians typically use this type of disc for precision deburring where a coarser abrasive would leave unwanted surface damage.

This disc is intended for use with straight shaft die grinders in both shop and field applications. The fine grade makes it appropriate for finishing passes on ferrous and non-ferrous metals where surface condition matters. The shank mount allows direct chuck installation on compatible rotary tools without additional adapters. Applications include deburring drilled holes, ground edges, machined ports, and weld spatter cleanup in light manufacturing, maintenance, and fabrication environments.
