08L502 - Walter ALU Aluminum Grinding Wheel 5-Inch x 1/8-Inch Type 27

Walter ALU™ Grinding Wheel: The Solution for Soft Metals

The Walter ALU™ Grinding Wheel (08L502) is a specialized abrasive tool engineered to tackle the unique challenges of working with aluminum and other non-ferrous metals. Standard grinding wheels often fail when applied to soft metals because the material melts and clogs the abrasive grain—a process known as "loading." Once a wheel is loaded, it stops cutting and begins to generate excessive heat, which can damage the workpiece and frustrate the operator. The Walter ALU™ line solves this problem with a proprietary formulation that resists clogging, ensuring consistent, aggressive cutting action throughout the life of the wheel.

Measuring 5 inches in diameter with a 1/8-inch thickness, this wheel strikes a balance between durability and precision. The 1/8-inch profile allows it to be used for intermittent light grinding and notching, making it a versatile addition to any fabricator's toolkit. It is constructed with a Type 27 depressed center, providing rigidity and safety for angle grinder applications.

Wax-Free for Immediate Welding

One of the most significant benefits of the Walter ALU™ wheel is its purity. Unlike many other aluminum-specific abrasives that rely on waxes or lubricants to prevent loading, the ALU™ wheel is manufactured without these additives. In a professional fabrication environment, this is a game-changer. Waxes can contaminate the metal surface, leading to porosity or weak welds if not thoroughly cleaned off with solvents. With the Walter ALU™, you can grind your joint and weld immediately, eliminating an entire step in the surface preparation process and increasing overall productivity.

Performance and Safety

This wheel is designed for fast, free cutting with minimal pressure, reducing operator fatigue during extended use. It is rated for a maximum speed of 12,200 RPM, ensuring compatibility with standard 5-inch angle grinders. Whether you are building aluminum trailers, repairing boat hulls, or fabricating custom architectural components, the Walter 08L502 delivers the reliability and finish quality required for professional results.
