Value Collection C121355 Quick-change Disc 4 in Medium

Product Description

The VALUE COLLECTION C121355 is a non-woven quick-change abrasive disc designed for surface conditioning, blending, and finishing tasks in metalworking and fabrication environments. Built with aluminum oxide abrasive material and rated at a medium grade, this disc delivers consistent cut and surface texture across a range of metals. It measures 4 inches in diameter and is rated for a maximum of 15,000 RPM, making it suitable for use with standard angle grinders and inline tools equipped with a Speed-Lok TR (Type III) attachment system. Installation requires no tools beyond the compatible mandrel. This disc is sold in a package quantity of 10.

This disc is intended for use in light industrial and shop environments where surface prep, rust removal, weld blending, or finishing passes are required. The non-woven construction resists loading and conforms to irregular surfaces better than bonded abrasive alternatives. It is appropriate for use by fabricators, pipefitters, maintenance mechanics, and metalworking tradespeople working on ferrous and non-ferrous substrates. The maroon color indicates a medium-grade conditioning material consistent with standard industry color coding for this abrasive type.

Installation Notes

Installation is performed by pressing the disc onto a compatible Speed-Lok TR mandrel until the button locks into place — no tools required. Always verify the tool spindle speed does not exceed the 15,000 RPM disc rating before use. Inspect the disc for damage or delamination before each use and discard any disc that shows signs of wear beyond the abrasive surface. Follow applicable OSHA abrasive wheel safety standards and wear appropriate PPE including eye and face protection during operation.
