Walter XTRACUT 4.5 Inch Ceramic Sanding Disc Medium Grit

Aggressive Cutting Power That Won't Burn Your Steel

As a welder, you know that time is money, and changing out glazed-over sanding discs is a waste of both. The Walter XTRACUT™ 4-1/2" Medium Sanding Disc (15A458) is built to keep you grinding longer and faster. This isn't your average sanding disc; it is packed with premium self-sharpening ceramic grains that fracture as you work, constantly exposing fresh, sharp cutting edges. This means the disc doesn't just rub against the metal—it bites in and hogs off material, even on tough steel surfaces.

One of the biggest headaches in grinding steel is heat buildup, which can warp your piece or cause discoloration that takes extra time to fix. Walter has solved this with integrated cooling agents right in the disc's bonding matrix. These agents lubricate the cut, keeping the workpiece significantly cooler than standard abrasives. You get a smooth, aggressive grind without the scorching. The "Medium" grit offers a perfect sweet spot, allowing you to strip down welds or mill scale quickly while leaving a manageable finish that is easy to blend out.

Whether you are prepping a joint, removing heavy spatter, or blending a weld seam, the XTRACUT™ disc gives you the control and longevity you need to finish the job without constant interruptions. Pair this 15A458 disc with your favorite 4-1/2" grinder and a turbo backing pad to experience a noticeable difference in how the abrasive handles heavy pressure. Stop fighting your tools and start cutting with the efficiency of Walter ceramic technology.
