Walter Enduro-Flex Stainless 7-Inch Flap Disc Grit 40 with Trimmable Backing

Smooth Finishes and Long Life for Professional Welders

Upgrade your grinding game with the Walter 15Q704 Enduro-Flex Stainless Flap Disc, a 7-inch powerhouse designed to make your work on stainless steel and aluminum faster, cleaner, and more comfortable. As a welder, you know that finishing stainless steel requires a delicate balance: you need aggressive material removal to level welds, but you also need to avoid overheating the metal which causes unsightly heat tint (blueing). This Grit 40 disc hits that sweet spot perfectly. It provides the bite needed for heavy stock removal while its advanced coating lubricates the cut, keeping the workpiece cool and reducing the need for extensive rework or polishing later.

One of the most frustrating aspects of grinding aluminum is "loading"—when the soft metal gums up the abrasive, rendering the disc useless long before the grit is actually worn out. The Enduro-Flex Stainless solves this with a non-loading formulation that keeps the grain open and cutting aggressively. But the real game-changer is the ECO-TRIM backing. Instead of throwing away a disc that still has plenty of good abrasive in the center, you can simply trim the backing against a piece of scrap metal to reveal fresh grit. This means you get up to three times the life out of a single disc, saving you money and trips to the tool crib.

Comfort is king during long shifts, and this disc delivers there too. The plant-fiber backing absorbs vibration much better than fiberglass or plastic, leading to a smoother feel and less fatigue in your hands and arms. It also runs quieter, contributing to a better shop environment. Whether you are blending TIG welds on a food-grade stainless tank or smoothing out aluminum frames, the Walter 15Q704 gives you a one-step solution for grinding and finishing, leaving a surface that is ready for final blending or painting. It fits any standard 7-inch grinder with a 7/8" arbor, so you can strap it on and get to work immediately.
