Merit Abrasives 69957399659 Quick-change Disc 240 Grit 3 in

Product Description

The MERIT ABRASIVES 69957399659 is a Power-Lock Type 2 quick-change abrasive disc designed for use with handheld disc sanders in metalworking applications. It measures 3 inches in diameter and carries a 240 grit rating, placing it in the very fine grade category. The abrasive material is aluminum oxide bonded to a rigid, X-weight 2-ply polyester backing that resists tearing and extends service life under sustained stock removal. The coated construction delivers a faster cut rate than standard single-layer discs. Rated to 20,000 RPM, this disc is suited for deburring, cleaning, and surface detailing work on metal substrates. Installation and disc changes are handled by licensed tradespeople and skilled metalworkers in fabrication and maintenance settings.

This disc is intended for use on 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It fits handheld disc sanders equipped with a Type S power-lock attaching system, making it a common choice in metal fabrication shops, MRO environments, and field service situations where fast disc changes and consistent finish quality are required. The 240 grit level is appropriate for final deburring passes, light surface conditioning, and detailing work where a finer finish is needed after coarser stock removal steps.

Installation Notes

Disc changes should be performed with the sander powered off and disconnected from its power source. Verify the spindle speed of the host tool does not exceed the 20,000 RPM disc rating before use. Inspect the disc for damage or delamination prior to each use and discard any disc showing tears, cracks, or separation of the backing layer. Wear appropriate PPE including eye protection and gloves when operating abrasive tools.
