15A478 - Walter XTRACUT 4.5-Inch Medium Grit QC Sanding Disc

Quick-Change Convenience for Professional Welders

Stop wasting time fumbling with flange nuts and pin wrenches. The Walter 15A478 XTRACUT™ Quick-Change Sanding Disc is designed to make your grinding and blending tasks faster and easier. Featuring a convenient spin-on/spin-off mounting system, this 4-1/2 inch disc lets you change abrasives in a snap, so you can get back to welding and finishing. Whether you are working in a custom fab shop or on a job site, the convenience of the QC system means less frustration and more arc time.

Don't let the convenience fool you; this is a serious industrial abrasive. The XTRACUT™ utilizes premium ceramic grain technology that cuts faster and lasts longer than traditional sanding discs. It is specifically formulated for use on steel and stainless steel, biting into the metal to remove stock quickly while leaving a consistent finish. The "Medium" grit rating makes it a versatile tool in your arsenal—aggressive enough to take down a weld bead but refined enough to blend surfaces smooth without leaving deep gouges that are hard to remove later.

One of the biggest challenges in grinding is heat buildup, which can ruin a perfect weld or discolor stainless steel. Walter has solved this with built-in cooling agents that lubricate the cut, keeping the workpiece cooler. This means you can grind longer without worrying about burning the metal. To get the best performance, ensure you pair this disc with the correct Walter Quick-Change rubber backing pad, which provides the necessary support and flexibility for contouring and flat grinding alike.
