Merit Abrasives 69957399714 Quick-change Disc 180 Grit 2in

Product Description

The MERIT ABRASIVES 69957399714 is a coated quick-change abrasive disc designed for use with Power-Lock Type 3 (TR/Type III) and Type R attaching systems on handheld disc sanders. The disc measures 2 inches in diameter and cuts at 180 grit, placing it in the very fine grade range. It uses aluminum oxide abrasive bonded to a rigid, X-weight 2-ply polyester backing for extended service life and a faster cut rate compared to lighter backing constructions. The disc is rated to a maximum of 30,000 RPM. Licensed HVAC techs, fabricators, and metal finishing trades install this disc for precision surface work where material removal must be controlled and consistent.

This disc is suited for deburring, cleaning, and detailing operations on 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It is intended for use with handheld disc sanders equipped with a TR (Type III) or Type R quick-change interface. The brown coloring indicates the aluminum oxide abrasive compound, and the rigid polyester backing makes it appropriate for flat or near-flat surface finishing rather than contoured work.

Installation Notes

Installation should be performed by a qualified technician familiar with angle grinder and disc sander safety practices. Verify that the tool spindle speed does not exceed the 30,000 RPM disc rating before mounting. Inspect the disc for damage before each use and replace immediately if cracking, tearing, or delamination is observed. Always wear appropriate eye and face protection when operating abrasive discs at speed.
