OVERVIEW

Walter ALU: The Standard for Aluminum Grinding

Fabricators working with aluminum know the frustration of a glazed grinding wheel. The Walter ALU Grinding Wheel is the industry standard solution, designed to deliver high-performance grinding on aluminum alloys without the common issues of loading and clogging. The model 08L705 is a 7-inch diameter, 1/4-inch thick wheel that provides exceptional durability and speed for heavy material removal tasks.

Standard grinding wheels are typically designed for steel and are too hard for soft metals. When used on aluminum, the metal heats up and melts into the pores of the wheel, rendering it useless in minutes. The Walter ALU wheel utilizes a unique abrasive blend and bonding system that resists this loading effect. It cuts cool and fast, ensuring that the heat is transferred away from the workpiece. This is critical when working on heat-sensitive aluminum alloys, as excessive heat build-up can alter the metallurgical properties of the material or cause warping.

This wheel is particularly effective for preparing aluminum for welding, as it leaves a clean surface free of contaminants. Since it requires no wax or liquid lubricants to prevent clogging, there is no residue left behind that could cause porosity in subsequent welds. The integrated 5/8-11 threaded hub ensures a secure fit to your angle grinder and improves balance, reducing operator fatigue during extended use. Whether you are building aluminum boats, truck bodies, or architectural structures, the Walter ALU wheel is an essential consumable for your shop.

FAQ

Aluminum is a soft metal with a low melting point. Standard wheels designed for steel will cause the aluminum to melt and clog (load) the wheel face, stopping it from cutting. The Walter ALU wheel is formulated to prevent this loading.

No, the Walter ALU wheel is designed to cut freely without the need for beeswax or other lubricants, which keeps your workpiece cleaner.

This wheel features a built-in 5/8-11 threaded hub, which screws directly onto the spindle of most standard 7-inch angle grinders.

While it can physically grind steel, it is not recommended. The bond is too soft for steel, meaning the wheel will wear out very quickly compared to a wheel designed for ferrous metals.

The maximum safe operating speed for the 08L705 is 8,600 RPM. Always ensure your grinder does not exceed this speed.

Yes, this is a Type 27 depressed center grinding wheel, designed for grinding at a 15 to 30-degree angle.

Walter ALU wheels are contaminant-free, making them safe for use in nuclear or food-grade applications where cross-contamination is a concern.

The integrated hub allows for tool-free mounting (spin-on), reduces vibration due to better centering, and eliminates the need for a separate flange nut.
