Merit Abrasives 63642505669 Quick-change Disc 3in 24G

Product Description

The MERIT ABRASIVES 63642505669 is a TR-style quick-change abrasive disc rated for demanding material removal applications. It measures 3 inches in diameter and is coated with aluminum oxide abrasive at 24 grit, placing it in the very coarse grade range. The cloth backing with an X-weight designation provides durability and flexibility under aggressive grinding conditions. The Type R attaching system allows for fast disc swaps without tools, reducing downtime during surface prep work. Maximum rated speed is 20000 RPM. This disc is sold individually and is intended for use by metal fabricators, welders, and trade professionals working on weld cleanup, rust removal, and surface conditioning tasks.

This disc is suited for use on metal surfaces in fabrication shops, maintenance environments, and field service situations. The Type R quick-change mount is compatible with TR-style backing pads commonly used with angle grinders and die grinders. The 24-grit aluminum oxide abrasive is well matched to heavy stock removal on ferrous metals, weld seam grinding, and deburring. The brown cloth-backed construction holds up to high-pressure applications where paper-backed discs would break down. It is ordered in multiples of 25 units.
