Walter Allsteel 7-Inch Flap Disc Grit 40 with Trimmable Backing

Aggressive Grinding Power for Tough Steel Jobs

When you are staring down a long bead of heavy weld on structural steel, you need an abrasive that bites hard and doesn't quit. The Walter Allsteel™ 7-inch Flap Disc (Grit 40) is built for exactly that kind of work. This isn't your average hardware store grinding wheel; it is a professional-grade tool designed to chew through steel with speed and precision. The secret lies in the special zirconia alumina grain blend. As you grind, the grains fracture to reveal sharp new cutting edges, meaning the disc stays aggressive from the first spark to the last.

We know that operator fatigue is a real issue when you are grinding all day. One of the best things about this Walter disc is that it does the work for you. You don't need to lean your entire body weight into the grinder to get it to cut. The high-performance grain slices through scale and weld metal with moderate pressure, saving your arms and back. It is perfect for those tough jobs like blending fillet welds, taking down sharp corners, or heavy deburring on plate steel. The 40 grit finish rips off material quickly, helping you get the part prepped and out the door faster.

Stop throwing away money on discs that still have life left in them. The Allsteel™ 15W704 features a trimmable backing pad. When the flaps wear down to the edge of the plastic backing, you don't have to toss the disc. You can simply trim the backing away to expose fresh abrasive material that was hiding underneath. This feature alone can drastically increase the life of your disc, giving you more grind time for your dollar. It is a smart design for welders who want to get every ounce of value out of their consumables.

This disc fits standard 7-inch angle grinders with a 7/8-inch arbor. Whether you are in a fab shop, a shipyard, or working on heavy equipment repair, the Walter Allsteel™ is the reliable workhorse you need in your tool crib. It delivers a consistent finish, runs smooth, and lasts long enough to finish the job. Upgrade your grinding game with a flap disc that is as tough as the steel you are working on.
