Merit Abrasives 69957399616 Quick-change Disc 50 Grit

Product Description

The MERIT ABRASIVES 69957399616 is a 1-inch diameter, Type II (TS) quick-change disc designed for use with handheld disc sanders in metalworking applications. It features a 50-grit aluminum oxide abrasive bonded to a polyester cloth backing rated at Y-weight, providing a rigid, durable cutting surface suitable for coarse material removal. The disc is rated to 40000 RPM and attaches via a Type S quick-change system, allowing fast swaps without tools. It is suited for deburring, cleaning, and surface detailing on a range of ferrous and non-ferrous metals.

This disc is intended for trade and industrial use where consistent abrasive performance is needed on stainless steel, aluminum, brass, bronze, titanium, and both hard and soft carbon steels. The coated aluminum oxide construction performs well in grinding and finishing passes on tight or contoured surfaces where a larger disc cannot reach. It is sized for compact handheld disc sanders commonly used in fabrication shops, maintenance environments, and field service work on metal assemblies.
