OVERVIEW

The Wheel That Eats Steel for Breakfast

If you are tired of grinding wheels that turn into dust halfway through a job or glaze over the second you lean into them, it’s time to switch to the Walter HP XX. This 7-inch beast is built for one thing: removing metal fast. Whether you are grinding down a heavy multipass weld on a structural beam or cleaning up a messy torch cut, the HP XX digs in and stays aggressive right down to the nub. It doesn’t just rub the metal; it removes it, saving you time and saving your arms from fighting the grinder all day.

Let’s talk about the hub. This wheel comes with a 5/8-11 threaded Spin-On hub built right in. That means no more hunting for that locking nut you dropped in the dirt, and no more fumbling with a pin wrench while your foreman is watching the clock. You just spin the old wheel off, spin this one on, and you are back to making sparks in seconds. The hub also keeps the wheel perfectly centered, so you don't get that annoying wobble that rattles your teeth and numbs your hands. It runs smooth, true, and fast.

The "XX" in the name stands for Xtra Life and Xtra Grinding. Walter designed this specifically for steel, so it’s tough enough to handle the heat and pressure of heavy fabrication without falling apart. It’s a Type 27 wheel, so it’s got that depressed center shape you need to get in close and grind at a comfortable angle. When you have a deadline to meet and a mountain of steel to grind, don't waste your time with cheap box-store wheels. Grab a Walter HP XX 08H705 and get the job done right the first time.

FAQ

This wheel features a 5/8-11 threaded Spin-On hub, designed to screw directly onto standard 7-inch angle grinder spindles.

While it can physically grind aluminum, it is not recommended. The HP XX is formulated for steel; using it on aluminum will likely cause the wheel to load up (clog) quickly. We recommend using a wheel specifically designed for non-ferrous metals.

No, the integrated hub eliminates the need for a separate flange nut or pin wrench for mounting.

The maximum safe operating speed is 8,600 RPM. Always ensure your grinder's no-load speed does not exceed this rating.

This is a Type 27 (depressed center) grinding wheel, suitable for grinding at angles between 15 and 30 degrees.

The HP XX is the premium version, offering a harder bond and higher quality grain for extended life and more aggressive removal rates in heavy-duty applications.
