Superior Abrasives A014839 Quick-change Disc 2in 240 Grit

Product Description

The SUPERIOR ABRASIVES A014839 is a Type R quick-change abrasive disc designed for fast material removal and surface finishing on metal and similar substrates. It measures 2 inches in diameter and cuts with 240-grit aluminum oxide abrasive, placing it in the very fine grade range. The cloth backing with an X-weight designation provides flexibility and durability under aggressive grinding or blending passes. A black button and maroon disc color make orientation and disc identification straightforward at the bench. This disc mounts via the Type R quick-change attaching system, allowing rapid swaps without additional tools. Fabricators, welders, and metalworkers install these in production and repair environments where consistent fine finishing is required.

This disc is suited for light deburring, surface blending, and finish work on ferrous and non-ferrous metals. The 240-grit rating makes it appropriate as a final or near-final pass in a progression sequence, smoothing scratch patterns left by coarser grits. At a maximum rated speed of 30,000 RPM, it is compatible with the compact die grinders and right-angle tools commonly used in fabrication shops, maintenance facilities, and on-site metalwork. It ships individually but is ordered in multiples of 100, making it a standard stocking item for shops with consistent throughput.

Installation Notes

A licensed or trained metalworker or fabricator should verify that the tool spindle speed does not exceed the 30,000 RPM maximum rating before mounting the disc. Inspect the disc for damage before each use and confirm the Type R button is fully seated on the mandrel. Always wear appropriate eye and face protection when operating abrasive discs. Follow ANSI B7.1 safety standards for the use, care, and protection of abrasive products.
