Merit Abrasives 69957399660 Quick-change Disc 320 Grit 3in

Product Description

The MERIT ABRASIVES 69957399660 is a coated quick-change abrasive disc designed for use with handheld disc sanders equipped with a Power-Lock Type S attaching system. Built on a rigid Y-weight 2-ply polyester backing, this 3-inch disc runs at up to 20,000 RPM and carries a 320-grit aluminum oxide abrasive surface. The extra-fine grit and durable coated construction make it well suited for precision deburring, surface cleaning, and detail finishing work on ferrous and non-ferrous metals. Fabricators, maintenance techs, and metal finishing professionals are the primary installers of this type of disc in production and service environments.

This disc is rated for use on 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It fits standard handheld disc sanders that accept the Type S quick-change mounting system. The brown disc color and silver button are characteristic of the Merit R766 series. Minimum order quantity is 50 units, with individual package quantity of 1, making it a standard replenishment item for shops that cycle through abrasives at volume.
