Walter Coolcut XX 7-Inch 36 Grit Resin Fiber Disc

Aggressive Grinding That Keeps Its Cool

When you have a mountain of heavy welds to grind down, you need an abrasive that bites hard and doesn't quit. The Walter 15X703 Coolcut XX™ 7-inch disc is built for the welder who wants to get the job done fast and move on to the next fit-up. With a coarse 36 grit, this disc is a beast at hogging off material. Whether you are leveling a multi-pass weld on structural steel or beveling a thick plate for penetration, the Coolcut XX™ digs in and removes metal rapidly without requiring excessive pressure from the operator.

One of the biggest frustrations with aggressive grinding is heat buildup, especially on stainless steel where heat tint can ruin the finish, or on aluminum where the disc gums up and loads. Walter solved this with their Cyclone Technology™. The disc geometry actually creates airflow between the abrasive and the workpiece, keeping the contact point cooler. This means you can grind aluminum without the disc clogging up instantly, and you can work on stainless with less risk of blueing the metal. It’s a smoother, cooler run that lets you maintain control.

Durability is where this disc truly shines in the shop. We've all used cheap fiber discs that lose their grit after two minutes of grinding, forcing you to stop and swap them out constantly. The Coolcut XX™ is designed to last up to six times longer than those standard discs. That means you spend more time with sparks flying and less time fumbling with your backing pad nut. For fabricators looking for a reliable, heavy-duty 7-inch disc that handles everything from carbon to alloys, this is the tool to keep in your grinder box.
