Merit Abrasives 69957399632 Quick-change Disc 120 Grit

Product Description

The MERIT ABRASIVES 69957399632 is a quick-change abrasive disc designed for use with Power-Lock Type 2 (TS/Type II) attachment systems on handheld disc sanders. At 1-1/2 inches in diameter, this coated aluminum oxide disc features a fine 120-grit surface on a rigid X-weight, Y-weight 2-ply cloth and polyester backing that extends service life and improves cut rate. The silver button attaching system locks quickly and releases cleanly. Rated to 30,000 RPM, it is well-suited for high-speed finishing passes in fabrication, maintenance, and surface prep work. Metalworking professionals and fabricators are the primary users of this disc type.

This disc is rated for use on 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. The 120-grit aluminum oxide abrasive targets deburring, cleaning, and detailing operations where a fine, controlled cut is needed. Its compact 1-1/2-inch diameter makes it effective in tight or contoured areas that larger discs cannot reach. Typical install scenarios include weld seam cleanup, edge deburring, and surface conditioning on fabricated metal components. The disc is intended for use with handheld disc sanders equipped with a TS (Type II) or Type S quick-change arbor.
