Merit Abrasives 69957399702 Quick-change Disc 180 Grit

Product Description

The MERIT ABRASIVES 69957399702 is a quick-change abrasive disc designed for handheld disc sanders in metalworking and fabrication applications. Built on a rigid Y-weight 2-ply polyester backing with an aluminum oxide abrasive coating, this disc delivers a faster cut rate and extended service life compared to lighter-backed alternatives. It attaches via a Power-Lock Type R system for secure, tool-free disc changes. Rated at 30,000 RPM maximum, the disc operates safely at high speeds. At 180 grit, it falls in the very fine grade range, making it well-suited for deburring, surface cleaning, and detailing work on metal components.

This disc is intended for use in metal fabrication, maintenance, and finishing environments where controlled material removal on hard and soft metals is required. Compatible material applications include 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It is designed for use with handheld disc sanders equipped with a Type R quick-change attachment system. The disc is sold individually with a minimum order quantity of 100 units, making it appropriate for shop stocking or production-line supply.
