OVERVIEW

Crush Heavy Grinding Jobs with Walter HP XX Type 28

When you have serious metal to move, you need a wheel that fights back. The Walter HP XX™ Type 28 Grinding Wheel (08K701) is built for welders who demand aggressive performance and refuse to waste time changing out worn discs constantly. This 7-inch wheel is a beast on steel, designed to rip through heavy welds, bevel thick plates, and smooth out rough surfaces with ease. If you are tired of wheels that glaze over or disintegrate under pressure, the HP XX™ is the upgrade your grinder deserves.

What sets this wheel apart is its Type 28 "saucer" shape. While most guys are used to the standard Type 27, the Type 28 offers a slightly different profile that can be a game-changer for comfort and access. It allows you to grind at shallower angles, making it easier to blend surfaces without digging in. It’s perfect for those long grinding sessions where maintaining a consistent, flat surface is key. Combined with Walter’s premium grain technology, this shape gives you control and power in one package.

Walter Surface Technologies has packed the HP XX™ with their most advanced bonding matrix. This means the grains stay sharp longer and the wheel holds its shape better, even under the heat and stress of heavy fabrication. You get a smoother feel, less vibration, and a lot more sparks flying where they should be. Whether you are in the field or in the shop, trusting your abrasives is half the battle. With the 08K701, you can lean into the work and let the wheel do the heavy lifting.

FAQ

A Type 27 wheel has a depressed center and a flat profile, typically used at a 15-30 degree angle. A Type 28 wheel has a 'saucer' shape, which is concave. This allows for grinding at shallower angles (often 0-15 degrees) and provides better access and surface contact for specific blending applications.

The HP XX™ line is primarily optimized for steel to ensure the most cost-effective removal rates. While it can physically grind other metals, Walter offers specific product lines (like HP Stainless) that are formulated to prevent contamination and heat buildup on stainless steel.

This wheel has a diameter of 7 inches and a thickness of 1/4 inch, making it a standard size for heavy-duty angle grinders.

No, this is a bonded abrasive grinding wheel (Type 28). It mounts directly to the grinder using the appropriate flange or arbor nut. Backing pads are typically used for resin fiber discs or flap discs.

Always wear a face shield over safety glasses, hearing protection, heavy-duty gloves, and flame-resistant clothing. Ensure the grinder's guard is properly adjusted and never exceed the maximum RPM rating of the wheel.

In industrial grinding, the cost of the wheel is often minor compared to the cost of labor. The HP XX removes material faster (reducing labor time) and lasts longer (reducing downtime for wheel changes), resulting in a lower total cost per finished part.

No. Type 28 wheels are 1/4-inch thick and designed for grinding (stock removal). They should never be used for cutting (cutoff) applications, as the side load forces during cutting are different from grinding and can cause dangerous wheel failure.

While not explicitly detailed in the short description, standard 7-inch grinding wheels typically feature a 7/8" arbor hole. Always verify your grinder's spindle size before purchasing.
