Walter Enduro-Flex ALU 7-Inch Flap Disc 60 Grit

Stop Clogging Your Discs on Aluminum

Every welder knows the frustration of grinding aluminum: you start with a fresh disc, and within minutes, it's gummed up, glazed over, and useless. The Walter Enduro-Flex ALU™ (15U706) is designed to solve exactly that problem. This 7-inch, 60-grit flap disc features a special lubricant coating that actively repels soft metals, preventing the "loading" effect that kills standard discs. This means you can keep grinding longer with a consistent bite, saving you from constantly swapping out consumables.

Get 3x More Life Out of Every Disc

Why throw away a disc when there is still good abrasive left near the center? Walter's patented Eco-Trim™ backing is a game-changer for shop efficiency. As the outer edge of the flaps wears down, you can simply trim the plastic backing against a piece of scrap metal to expose fresh abrasive material underneath. This feature allows you to use the disc almost down to the hub, giving you up to three times the lifespan of a standard fiberglass-backed disc. It’s a simple feature that puts money back in your pocket.

Smooth, Contaminant-Free Finishing

When working with aluminum, cross-contamination is a major concern. The Enduro-Flex ALU™ is guaranteed free of iron, sulfur, and chlorine, ensuring you won't introduce rust-causing contaminants into your base metal. The 60-grit zirconia alumina grain provides a perfect balance between aggressive stock removal and a smooth, blendable finish. It runs quiet and vibration-free, reducing operator fatigue during long grinding sessions. If you fabricate aluminum trailers, boats, or tanks, this is the disc you need in your arsenal.
