Walter ZIP ALU 6-Inch Type 27 Aluminum Cutting Wheel (Pack of 5)

Stop Your Wheels from Gumming Up on Aluminum

Every welder knows the frustration of taking a standard cutoff wheel to a piece of aluminum. One minute you're cutting, and the next, the wheel is glazed over, smoking, and fighting you every inch of the way. That's called loading, and it kills your productivity. The Walter ZIP ALU™ 6-inch cutting wheel is the answer to that headache. It is built with a special recipe that prevents the soft aluminum from sticking to the wheel, so you get a fresh cut from the first spark to the nub.

This isn't just any slicer; it's a Type 27 wheel. That means it has a depressed center (a raised hub), which gives the wheel more backbone. If you've ever had a thin wheel wobble on you, you know why that stiffness matters. It helps you keep a straight line and allows you to get into tight spots or cut flush against a bracket without the mounting nut getting in the way. At 3/64" thick, it's thin enough to scream through material without bogging down your grinder, but tough enough to handle the job.

Whether you are building aluminum boat hulls, fixing a trailer, or fabricating custom tanks, the ZIP ALU™ saves you time. You won't have to stop to swap out a clogged wheel halfway through a cut, and you won't have to lean on the grinder to get it to bite. It cuts cool, which means less burr on the backside and less time with a file or deburring tool later. This 5-pack gives you enough ammo to tackle a serious project without running back to the supply store.

Why Choose ZIP ALU?

Standard wheels turn aluminum cutting into a wrestling match. The ZIP ALU™ turns it into a hot knife through butter. It’s designed to self-sharpen and shed the aluminum chips that normally ruin a wheel. If you work with aluminum, brass, or copper, keep a pack of these in your box—your grinder (and your patience) will thank you.
