Tru-maxx 505330 Quick-change Disc 60 Grit 3in Zirconia

Product Description

The TRU-MAXX 505330 is a coated abrasive quick-change disc designed for aggressive material removal on metal and other hard surfaces. Built on a fiber backing, it uses zirconia alumina abrasive material at 60 grit, placing it in the medium grade range. The disc measures 3 inches in diameter and is rated for a maximum of 20,000 RPM, making it suitable for high-speed angle grinders and die grinders equipped with a Type S quick-change attachment system. The blue disc face and silver button are standard identifiers for this product line. At 0.03 pounds per disc, it adds minimal weight to the tool setup.

This disc is intended for surface grinding, weld blending, edge deburring, and stock removal tasks common in metal fabrication, maintenance, and repair environments. The Type S quick-change interface allows rapid disc swaps without tools, reducing downtime during production or field work. It is well suited for use by metalworkers, maintenance technicians, and fabrication professionals working on ferrous and non-ferrous metals.
