Walter Coolcut XX 4.5-Inch 50 Grit High-Performance Sanding Disc

Grind Faster, Run Cooler, Last Longer

As a welder, you know that time spent changing out worn-out sanding discs is time you aren't welding or finishing. The Walter Coolcut XX™ 4-1/2" Sanding Disc (Grit 50) is built to keep you working. With Walter's exclusive Cyclone Technology™, this disc is a beast when it comes to hogging off material. Whether you are leveling a heavy weld seam, blending a corner, or prepping a surface for paint, the 15X455 bites hard and cuts fast—up to twice as fast as the standard discs you might be used to.

One of the biggest frustrations in metal finishing is a disc that loads up or glazes over after just a few minutes of work. The Coolcut XX™ is designed to resist loading, even on softer metals like aluminum. It runs significantly cooler than standard fiber discs, which means you don't have to worry as much about scorching your stainless steel or warping thin sheet metal. The 50 grit abrasive is aggressive enough to take down high spots quickly but controlled enough to leave a consistent scratch pattern that is easy to blend out if needed.

Durability is where this disc truly shines. It is rated to last up to six times longer than ordinary sanding discs. That means fewer trips to the tool crib and less time fumbling with the backing pad nut. You can grind longer with a single disc, maintaining your rhythm and focus on the fabrication at hand. It works seamlessly on carbon steel, stainless, and alloys, making it the only disc you need to grab for most of your grinding and blending jobs.

To get the most out of the Walter 15X455, pair it with a high-quality turbo or standard backing pad on your 4-1/2" angle grinder. The disc is designed to handle the high RPMs of modern grinders (up to 13,300 RPM) without shedding grain prematurely. If you are tired of burning through cheap discs that stop cutting halfway through the job, upgrade to the Coolcut XX™ and experience the difference that premium abrasive technology makes in your daily grind.
