Walter ZIP ALU 7-Inch Type 27 Cutting Wheel for Aluminum

Cut Aluminum Like Butter Without the Clog

Every welder knows the headache of cutting aluminum with a standard wheel. It cuts fine for a few seconds, then the metal heats up, gums up the grit, and suddenly you're just rubbing a smooth rock against your workpiece. The Walter ZIP ALU™ 7" cutting wheel changes the game. It is specifically built to resist clogging, keeping the abrasive grains exposed and sharp so you can slice through aluminum, brass, and copper without stopping to change wheels or force the cut.

Designed for the Real World

This isn't just a standard wheel with a different label. The 11U172 features a Type 27 depressed center, which is a favorite among pipe welders and fabricators. The raised hub pushes the locking nut back, letting you get the wheel flat against a surface for flush cuts or into tight corners without the grinder hardware getting in the way. The 1/16" thickness is the sweet spot—thin enough for a lightning-fast cut that doesn't heat up the metal, but thick enough to handle the torque of a 7-inch grinder.

Cleaner Cuts, Less Prep

Because the ZIP ALU™ cuts cool and free, it leaves a cleaner edge with less burr compared to wheels that drag and melt their way through the metal. This means less time spent deburring and prepping your joint for welding. Whether you are building aluminum boat hulls, truck boxes, or custom architectural pieces, this wheel keeps your production moving. It even handles steel if you need it to, making it one of the most versatile wheels to keep in your job box.
