Walter Coolcut Resin Fibre Sanding Disc, 4-1/2 in x 60 Grit, Steel Applications

Smooth Grinding and Blending for Welders

When you need to knock down a weld or clean up a steel surface without breaking the bank, the Walter Coolcut 4-1/2" 60 Grit Sanding Disc is your go-to abrasive. Designed with the practical welder in mind, this disc fits standard 4-1/2 inch angle grinders and provides the bite you need to get the job done quickly. The 15C456 is built to handle the daily grind of the fabrication shop, offering a reliable solution for everything from stripping mill scale to blending out bead profiles.

One of the biggest frustrations with cheaper sanding discs is how quickly they heat up and stop cutting. Walter has solved this with their Coolcut technology. These discs are designed to run cooler, which means they don't just burn the metal—they actually cut it. This is a huge advantage when you are working on visible parts where heat marks would ruin the look of the project. The 60 grit abrasive is perfect for that middle stage of finishing: it's not as aggressive as a 36 grit that leaves deep scratches, but it removes material much faster than a 120 grit finishing disc.

The secret to the Coolcut's longevity is the high-quality fibre backing. It holds the abrasive grains firmly in place, even under the pressure of heavy-handed grinding. This means you get more work out of every disc, saving you time on changeovers and money on consumables. Whether you are prepping a chassis for welding, cleaning up repairs, or smoothing out a gate, these discs provide a consistent, smooth finish on steel. Pair this with a proper backing pad, and you have a versatile tool that belongs in every welder's toolbox.
