Walter Quick-Step XX 6-Inch Sanding Disc 120 Grit

Cool Cutting and Long Life for Professional Welders

For welders and fabricators who need a reliable solution for blending and finishing, the Walter Quick-Step XX 6" Sanding Disc (15V612) is a workshop essential. This 120-grit abrasive disc is built to tackle the toughest finishing jobs on steel, stainless steel, and aluminum. The "XX" designation stands for extra life, and this disc delivers exactly that. Thanks to its self-sharpening grains, you get a disc that cuts faster and lasts longer than traditional sanding pads, helping you power through projects without constantly stopping to swap out worn abrasives.

Heat buildup is the enemy of a good finish, especially on stainless steel where blue discoloration can ruin the look of a weldment. Walter has solved this with a specialized cooling agent infused directly into the disc. This technology keeps the workpiece cool, preventing heat tint and reducing the need for post-weld pickling or extensive rework. It allows you to grind and blend aggressively while keeping the metal surface pristine. The hook-and-loop backing system makes attachment to your grinder's backing pad instant and secure, ensuring you spend more time working and less time setting up.

This disc excels in versatility. While it is rigid enough for flat surface finishing, using it with a cushioned interface pad transforms it into a flexible tool capable of hugging the curves of railings, pipes, and automotive parts. The 120-grit finish leaves a smooth, consistent surface that is often paint-ready or perfectly prepped for a mirror-polish step. Whether you are cleaning up TIG welds on aluminum or blending a corner on a stainless steel cabinet, the Walter Quick-Step XX gives you the control and durability professional welders demand.
