Walter Enduro-Flex ALU 7-Inch Aluminum Grinding Flap Disc 40 Grit

Stop Clogging Your Wheels on Aluminum

Every welder knows the frustration of grinding aluminum: you start with a fresh wheel, and within seconds, it's gummed up with soft metal, turning your grinder into a glorified polisher that generates more heat than sparks. The Walter Enduro-Flex ALU 7" Flap Disc is built to solve exactly that problem. If you are fabricating aluminum tanks, trailers, or boat hulls, this is the wheel you need in your arsenal.

This 40-grit flap disc eats through aluminum without loading up. It uses a special coating that keeps the aluminum from sticking to the grains, meaning the disc keeps cutting aggressively from the first pass to the last. It’s sized at 7 inches with a standard 7/8" arbor, perfect for your heavy-duty angle grinders when you need to remove welds or bevel edges quickly. The finish is smooth and consistent, saving you time on cleanup.

One of the best features is the trimmable backing. Usually, when the edge of a flap disc wears down, you have to toss it, even if there's plenty of abrasive left in the center. With this Walter disc, you can safely trim the plastic backing away against a piece of scrap metal, exposing fresh flaps and getting way more life out of a single disc. It saves you money and keeps you grinding longer without stopping to swap wheels.
