Merit Abrasives 69957399649 Quick-change Disc 24 Grit

Product Description

The MERIT ABRASIVES 69957399649 is a Power-Lock Type 2 quick-change abrasive disc designed for aggressive material removal on metal surfaces. Measuring 3 inches in diameter, this disc uses aluminum oxide abrasive at 24 grit, which puts it in the extra-coarse range for rapid stock removal, deburring, and surface preparation. The disc is cloth and polyester backed with a Y-weight, 2-ply construction, making it rigid enough for consistent contact on flat and contoured work surfaces. It is rated to a maximum of 20,000 RPM and mounts via a Type S attaching system compatible with TS (Type II) quick-change holders. Fabricators, maintenance technicians, and metalworkers install this disc for production-level grinding and finishing tasks.

This disc is suited for handheld disc sander applications across a wide range of metals, including 300 and 400 series stainless steel, aluminum, brass, bronze, hard carbon steels, soft carbon steels, and titanium. The extra-coarse 24-grit aluminum oxide grain cuts aggressively on tough alloys and is well matched to deburring, cleaning, and detailing tasks on stainless and soft metals. The brown cloth backing holds up under the friction and heat generated during heavy grinding passes, making this a practical choice for both production shop environments and field service work.

Installation Notes

Mounting and disc changes should be performed by qualified metalworking or maintenance personnel with the tool unplugged or pneumatic supply disconnected. Verify that the spindle speed of the host tool does not exceed the 20,000 RPM disc rating before operation. Inspect the disc for tears, delamination, or damage before each use and discard any disc that shows signs of wear beyond its abrasive surface. Follow applicable ANSI and OSHA abrasive product safety standards, including use of appropriate eye and face protection during grinding operations.
