OVERVIEW

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™ 5" Flap Disc is designed to solve exactly that problem. With a coarse 40 grit rating, this disc is built for heavy stock removal and blending, featuring a special coating that keeps the disc cool and prevents the aluminum from sticking to the abrasive grains.

Get More Value from Every Disc

Why throw away a flap disc when there's still good abrasive left in the center? Walter's innovative Eco-Trim™ backing lets you trim away the plastic edge as the flaps wear down. This simple feature allows you to use the inner portion of the flaps that would normally go to waste, giving you up to 3x the life of a standard fiberglass disc. It’s a smart design that puts money back in your pocket by reducing how often you need to restock.

Fast Changes, Smooth Grinding

Time is money in the shop. The Spin-On system means you can spin this disc right onto your 5-inch grinder without fumbling for a flange nut or a wrench. It centers itself perfectly every time, reducing vibration and operator fatigue. Whether you are building aluminum trailers, repairing boat hulls, or fabricating custom tanks, the Enduro-Flex ALU™ delivers a smooth, consistent finish without the headache of constant disc changes due to loading.

FAQ

Aluminum is a soft metal with a low melting point, which causes it to melt and clog (load) standard abrasives. The Enduro-Flex ALU has a special coating and grain structure designed to prevent this loading.

Eco-Trim is a trimmable plastic backing. As the abrasive flaps wear down to the edge of the backing, you can trim the plastic away to expose fresh abrasive, extending the life of the disc.

No, this is a Spin-On disc with an integrated hub. It threads directly onto the 5/8"-11 spindle of your angle grinder.

While it physically can grind steel, it is formulated for soft metals. Using it on hard steel may result in faster wear compared to the standard Enduro-Flex Stainless series.

Yes, the Enduro-Flex ALU is free of iron, sulfur, and chlorine, making it safe for use on aluminum where cross-contamination must be avoided.

Always check the label on the specific disc, but generally, 5-inch flap discs are rated for approximately 12,200 RPM.

You can trim the backing by running the edge of the backing against a piece of scrap metal or using a trimming tool while the grinder is running, carefully following safety protocols.
