Description

The MERIT ABRASIVES 63642505652 is a TR-style quick-change abrasive disc designed for fast material removal and surface finishing in trade and industrial applications. The disc measures 2 inches in diameter and uses aluminum oxide abrasive at 120 grit, a fine-grade cut suited for blending, deburring, and light stock removal on metal surfaces. Backed with X-weight cloth for durability and flexibility, the disc is rated to 30000 RPM. It is sold individually with a minimum order quantity of 25 units, making it a standard consumable for shops and field technicians who cycle through abrasives regularly.

This disc is suited for use with TR (Type III) quick-change disc holders on right-angle die grinders and similar rotary tools. The coated aluminum oxide construction performs on ferrous metals, stainless steel, and general fabrication work. The black retention button locks into compatible TR mandrels without tools, allowing rapid disc swaps during production grinding, weld blending, or surface prep work. It is commonly used by pipefitters, sheet metal workers, and general fabricators in both shop and field settings.

Follow ANSI B7 standards and applicable shop safety protocols when operating abrasive tools, including use of appropriate eye and face protection.
