Walter 7-Inch Quick-Step Blendex Disc Coarse Grade

Achieve Flawless Finishes on Stainless and Aluminum

As a welder, you know that the job isn't done until the finish looks right. The Walter 7" Quick-Step Blendex Disc (Coarse) is your go-to tool for turning a rough, welded assembly into a professional-grade product. This disc is specifically designed to tackle the challenges of metal finishing where a grinding wheel is too aggressive, but a standard sanding disc clogs too fast. It is the perfect solution for cleaning up heat-affected zones (HAZ) on stainless steel, removing surface rust, or stripping paint before laying down a bead.

The "Coarse" grit rating on this Blendex disc gives you enough bite to remove light weld spatter and blend out minor imperfections, yet it leaves a smooth, scratch-consistent surface that is often ready for painting or coating immediately. If you work with aluminum, you will appreciate the open-web design that resists loading. Aluminum dust passes through the fibers rather than packing in, meaning you get more life out of every disc and spend less time swapping out clogged abrasives. The 7-inch size covers large surface areas quickly, making it ideal for tank fabrication, architectural metalwork, and trailer repair.

Time is money in the shop, and the Quick-Step mounting system saves you plenty of it. No more fumbling with center nuts or wrenches; simply peel off the old disc and slap on the new one. The hook-and-loop backing holds tight even at speed but releases easily when you need it to. This system allows you to progress through different grits in seconds, taking a workpiece from a rough weld to a mirror-ready prep in record time.

Whether you are blending a corner weld, cleaning up a repair patch, or putting a decorative brushed finish on a stainless countertop, the Walter 07R702 gives you the control and consistency you need. It conforms to the metal, preventing gouging and undercutting, so you preserve the integrity of your weld while making it look its best.
