15C512 - Walter COOLCUT 5-Inch 120 Grit Aluminum Oxide Fibre Disc

Smooth Finishes with Cool Cutting Action

As a welder or fabricator, you know that the finishing step is just as critical as the weld itself. The Walter COOLCUT™ 5-inch sanding disc (SKU: 15C512) is built to help you achieve that perfect, paint-ready finish without fighting your equipment. With a fine 120 grit abrasive, this disc is your go-to tool for the final stages of surface preparation. Whether you are cleaning up light spatter, removing rust, or blending out scratch marks from coarser abrasives, this disc gives you the control you need to leave a smooth, professional surface.

One of the biggest frustrations in metal finishing is heat buildup. Overheating your workpiece can cause discoloration, warping, and can even alter the properties of the metal. Walter has solved this with their COOLCUT technology. These discs are infused with special cooling agents that actively reduce friction and heat generation during use. This means you can work longer and apply the necessary pressure without worrying about burning the steel. The result is a cleaner finish and a cooler workpiece that is ready for the next stage of fabrication immediately.

The 15C512 features premium aluminum oxide grains that stay sharp. Unlike cheaper discs that glaze over and stop cutting after a few minutes, the electrostatic grain application on these discs ensures that fresh cutting edges are always in contact with the metal. The heavy-duty fibre backing holds up to aggressive use, resisting tearing even when you are working on edges or uneven surfaces. When paired with a proper turbo or standard backing pad, this disc transforms your 5-inch grinder into a precision finishing tool.

Stop wasting time with discs that wear out too fast or damage your work with excessive heat. Upgrade to the Walter COOLCUT 120 grit disc for a smoother, cooler, and more consistent sanding experience. It’s the reliable choice for general-purpose steel fabrication, maintenance repairs, and automotive bodywork.
