Merit Abrasives 63642505673 Quick-change Disc 3in 60G

Product Description

The MERIT ABRASIVES 63642505673 is a TR-style quick-change abrasive disc designed for fast material removal on metal and other hard surfaces. Running a 60-grit aluminum oxide grain on an X-weight cloth backing, this disc delivers medium-grade cutting action with durability suited to grinding, blending, and surface prep work. The coated abrasive construction resists loading and holds up under the heat and pressure common in fabrication and weld-prep applications. At a rated maximum of 20,000 RPM, it is compatible with standard TR and Type R quick-change disc holders used across the trade. The 3-inch diameter fits compact angle grinders and die grinders commonly used in HVAC, plumbing, and sheet metal work.

This disc is a fit for surface preparation tasks in light fabrication shops, HVAC ductwork fitting, pipe fitting, and general metalworking. The quick-change TR attachment system allows tool-free disc swaps, reducing downtime during production runs. The cloth backing and aluminum oxide grain make it a reliable choice for grinding mild steel, stainless, and aluminum where a medium grit cut is appropriate. Sold individually with a minimum order quantity of 25 units.
