Merit Abrasives 69957399644 Quick-change Disc 120 Grit 2in

Product Description

The MERIT ABRASIVES 69957399644 is a 2-inch coated quick-change abrasive disc designed for use with Power-Lock Type 2 (TS / Type II) attachment systems on handheld disc sanders. Built around aluminum oxide grain on a rigid X-weight, 2-ply cloth and polyester backing, this disc runs at up to 30,000 RPM and delivers a consistent cut at 120 grit. The brown coated surface resists loading, and the Y-weight polyester backing adds durability for extended service life in high-cycle finishing work. Licensed tradespeople and fabrication professionals working in metal finishing, deburring, and surface prep reach for this disc when cycle time and disc life both matter.

This disc is suited to deburring, cleaning, and detail finishing on 300 Series stainless steel, brass, bronze, hard and soft carbon steels, and titanium. The rigid backing makes it effective on flat and near-flat surfaces where consistent stock removal is needed. It mounts to any handheld disc sander that accepts a TS (Type II) or Type S quick-change attaching system, making tool changes fast without extra hardware. Typical applications include weld cleanup, burr removal after drilling or plasma cutting, and light surface conditioning before inspection or coating.

Installation Notes

Mounting and disc changes on quick-change systems are performed by metal fabricators, maintenance technicians, and production grinders. Before mounting or removing the disc, power down the tool and confirm the spindle has come to a complete stop. Do not exceed the 30,000 RPM maximum speed rating marked on the disc. Inspect the disc for cracks, tears, or damage before each use and discard any disc that shows signs of deterioration.
