Merit Abrasives 66254449282 Quick-change Disc 1 in Aluminum Oxide

Product Description

The MERIT ABRASIVES 66254449282 is a non-woven aluminum oxide quick-change disc designed for surface conditioning, blending, and finishing on a range of metals and composites. Built on a flexible polyester and nylon web backing, this 1-inch disc attaches via a Type S Power-Lock system for fast, tool-free disc changes. Rated to 40,000 RPM, it is suited for high-speed die grinders and inline grinders used in production and maintenance environments. The medium grade provides moderate material removal with a smear-free finish, making it a reliable choice for techs and fabricators working on tight-tolerance surfaces.

This disc is engineered for use on 300 Series Stainless, 400 Series Stainless, Fiberglass and Composites, Hard Carbon Steels, Soft Carbon Steels, Super Alloys, Titanium, and Tool Steels. Compatible machines include die grinders, handheld disc sanders, inline grinders, and straight grinders. The 1-inch diameter makes it particularly effective in restricted-access areas where larger discs cannot reach. It is sold individually with a minimum order quantity of one.

Installation Notes

Installation is performed by fabricators, machinists, or maintenance technicians using compatible quick-change grinders or sanders. Before disc changes, power down the tool and allow all moving parts to come to a complete stop. Confirm the tool spindle speed rating does not exceed the disc maximum RPM of 40,000 before operation. Always use appropriate eye and hand protection when operating abrasive discs.
