06U604 - Enduro-Flex Alu 6-Inch Grit 40 Spin-On Flap Disc

Stop Clogging and Start Grinding

If you work with aluminum, you know the frustration of putting on a fresh flap disc only to have it gum up and stop cutting after just a few passes. The Walter Enduro-Flex Alu™ 6" Blending Disc (06U604) is the solution you have been waiting for. Specifically formulated for aluminum and other soft metals, this disc refuses to clog. Its special coating keeps the abrasive grains clean and sharp, allowing you to grind faster and longer without constantly stopping to change discs.

Get More Value from Every Disc
Standard flap discs often get thrown away while there is still plenty of good abrasive left near the center. Walter's innovative Eco-Trim™ backing changes the game. When the outer edge wears down, you can simply trim the backing material to reveal fresh, unused abrasive underneath. This unique feature allows you to get up to three times more life out of a single disc compared to competitors, putting money back in your pocket.

Fast Changes, Smooth Finishes
Time is money in any shop. The Spin-On mounting system lets you spin this disc onto your grinder in seconds—no keys or flange nuts required. The 6-inch diameter provides excellent coverage for larger jobs, while the 40 grit offers aggressive removal rates for taking down welds and smoothing surfaces quickly. Whether you are building aluminum trailers, repairing boat hulls, or fabricating custom parts, the Enduro-Flex Alu™ delivers the high-performance consistency professional welders demand.
