Walter Coolcut XX 5-Inch 60 Grit Resin Fiber Sanding Discs (Pack of 50)

Rip Through Welds Faster

When you have a stack of metal to finish and a deadline to meet, you need an abrasive that doesn't quit. The Walter Coolcut XX 5-inch sanding disc (15X506B) is built for welders who need aggressive bite and long life. This isn't your average sandpaper; it's a high-performance tool equipped with Walter's Cyclone Technology. The unique spiral design isn't just for looks—it aggressively clears swarf and keeps the disc cutting freely, so you don't have to push as hard to get the metal moving. With a 60-grit rating, it is perfect for knocking down weld beads and blending surfaces without gouging the base metal too deeply.

One of the biggest frustrations in grinding stainless steel or aluminum is heat buildup. If the metal gets too hot, you risk bluing the steel or clogging the disc with soft aluminum. The Coolcut XX is designed to breathe. Its cooling channels dissipate heat rapidly, allowing you to grind longer without burning the workpiece. This means less rework and a cleaner finish right off the grinder. Walter claims these discs cut twice as fast as regular fiber discs, and in the hands of a skilled welder, that speed difference is noticeable immediately.

This pack contains 50 discs, ensuring you aren't running back to the supply crib in the middle of a job. They mount easily to your 5-inch grinder with a standard backing pad and nut. Whether you are fabricating structural steel, polishing up an aluminum tank, or blending sanitary stainless welds, the Coolcut XX gives you the control and power you need. Stop wasting time with discs that glaze over after two minutes—switch to Walter and feel the difference in every pass.

Built for the Grind

Durability is key in a fabrication shop. These discs are manufactured to hold their shape and grain retention even under heavy pressure. The 60-grit abrasive is tough enough for carbon steel but refined enough for preparing surfaces for finer finishing steps. Upgrade your grinding game with a disc that works as hard as you do.
