Merit Abrasives 63642505655 Quick-change Disc 2in 180G

Product Description

The MERIT ABRASIVES 63642505655 is a TR-style quick-change abrasive disc designed for fast material removal and surface finishing in metalworking, fabrication, and maintenance applications. Measuring 2 inches in diameter, this disc features a 180-grit aluminum oxide abrasive bonded to a cloth backing with an X-weight backing construction. The coated brown finish and black center button are consistent with Type R quick-change compatibility, allowing tool-free disc swaps on standard TR/Type R grinders and die grinders. With a maximum rated speed of 30,000 RPM, it suits high-speed rotary tools commonly used by fabricators, pipefitters, and general metal tradespeople.

This disc is suited for fine surface conditioning, light deburring, and prep work on ferrous and non-ferrous metals. At 2 inches in diameter, it fits compact die grinders used in tight spaces such as pipe joints, weld seams, and structural steel connections. The 180-grit very fine grade makes it appropriate for finishing passes rather than aggressive stock removal. It is sold individually but requires a minimum order quantity of 25 units, making it practical for shop stock or fleet service vehicle kits.

Installation Notes

Installation and disc changes should be performed with the grinder powered off and disconnected from its power source or air supply. Verify that the mandrel or holder is rated for TR/Type R discs before mounting. Do not exceed the 30,000 RPM maximum rated speed of the disc. Inspect the disc for damage before each use and discard any disc that shows cracking, delamination, or uneven wear.
