08L500 - Walter ALU 5-Inch Aluminum Grinding Wheel Type 27

Professional Grade Aluminum Grinding Solution

The Walter ALU Grinding Wheel (08L500) is a high-performance abrasive specifically engineered for 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 (loads) the abrasive grain, rendering the wheel useless and creating excessive heat. The Walter ALU series utilizes a specialized bond and grain structure that resists loading, ensuring a continuous, aggressive cut throughout the life of the wheel.

One of the critical technical advantages of this product is its purity. It is manufactured free of waxes and lubricants. In many aluminum grinding applications, users apply wax to standard wheels to prevent clogging, which subsequently contaminates the base metal. This contamination must be chemically cleaned before welding to prevent porosity and weld defects. The Walter ALU wheel eliminates this step entirely. By grinding without additives, it leaves a clean, bare metal surface that is ready for immediate welding, significantly streamlining fabrication workflows.

Designed as a Type 27 depressed center wheel, it is optimized for grinding at angles between 15 and 30 degrees, making it ideal for weld removal, beveling, and heavy stock removal on flat or curved surfaces. With dimensions of 5" x 1/4" x 7/8", it fits standard 5-inch angle grinders. Industrial MRO professionals rely on the Walter ALU line for its ability to maintain high removal rates without the downtime associated with wheel changes due to glazing or loading.
