Norton 662611-29721 Avos Speed Lok 60 Grit Disc 4.5 in

Product Description

The NORTON 662611-29721 is an Avos Speed Lok quick-change abrasive disc designed for aggressive material removal on metal and other hard surfaces. Built with a Zirconia Alumina abrasive, this disc delivers a sharp, self-renewing cut that holds up under high-pressure grinding applications. At 60 grit, it sits in the coarse range, making it well suited for weld removal, surface prep, and heavy stock removal. The Speed Lok attachment system allows fast, tool-free disc changes on compatible right-angle grinders. Sold in a box of 10 discs, it is sized at 4.5 inches in diameter and carries a package weight of 5 pounds.

This disc is used across metal fabrication, structural steel work, pipeline work, and general industrial grinding applications. The 60 grit Zirconia Alumina construction is particularly effective on carbon steel, stainless steel, and other ferrous metals where rapid stock removal is the priority. It is a common choice for professional grinder operators, welding technicians, and fabricators who require consistent cut rate over extended use cycles. The Speed Lok quick-change interface reduces downtime during disc swaps in production environments.
