06U456 - Walter Enduro-Flex ALU 4.5 Inch Grit 60 Spin-On Flap Disc

Master Aluminum Finishing with Enduro-Flex ALU™

Welders know that aluminum is a different beast compared to steel. It's soft, it heats up quickly, and it loves to gum up your grinding wheels. The Walter Enduro-Flex ALU™ 4-1/2" Flap Disc (06U456) is the answer to these frustrations. Specifically formulated for aluminum and other heat-sensitive metals, this disc allows you to blend welds and finish surfaces without the constant interruption of a clogged wheel. The secret lies in the advanced coating that resists glazing and loading, keeping the zirconia alumina grains sharp and cutting freely from the first pass to the last.

Get more mileage out of every disc with the innovative Eco-Trim™ backing. We've all thrown away flap discs that still had plenty of abrasive left in the center just because the edge was worn out. With Eco-Trim™, you can safely trim back the plastic support to reveal fresh, unused abrasive material. This simple feature can triple the life of your disc, saving you money and trips to the supply cabinet. The Grit 60 composition offers a perfect balance between aggressive material removal and a smooth finish, making it a versatile choice for most aluminum fabrication tasks.

Convenience is key in a busy shop, and the Spin-On mounting system delivers just that. Forget hunting for a pin wrench; simply spin the disc onto your 4-1/2" or 6" grinder and you're ready to work. The vibration-free performance reduces operator fatigue, while the cool-cutting action protects your workpiece from heat discoloration. If you fabricate aluminum trailers, boats, or architectural features, the Walter Enduro-Flex ALU™ is the reliable, high-performance tool you need to achieve a professional finish every time.
