Merit Abrasives 63642505648 Quick-change Disc 50 Grit

Product Description

The MERIT ABRASIVES 63642505648 is a TR-style quick-change abrasive disc designed for fast material removal on metal and similar surfaces. At 2 inches in diameter with a 50-grit coarse aluminum oxide coating on a cloth backing, this disc delivers aggressive stock removal suited to grinding, blending, and deburring tasks. The Type R attaching system allows tool-free disc swaps, reducing downtime during production or job-site work. Rated to 30,000 RPM, it is compatible with standard TR/Type R quick-change angle-head grinders and die grinders used by fabricators, pipefitters, and metalworking tradespeople.

This disc is used in metal fabrication shops, pipe shops, and field service applications where coarse surface prep is required before welding, coating, or further finishing. The 2-inch diameter makes it well suited to working in tight spaces, around pipe welds, and on contoured surfaces where larger discs cannot reach. Sold individually, with a minimum order quantity of 25 units, it is appropriate for shop stocking or consumable replenishment orders.
