08L900 - Walter ALU 9-Inch Aluminum Grinding Wheel Type 27

High-Performance Aluminum Grinding with Walter ALU™

The Walter 08L900 ALU™ Grinding Wheel is a premier abrasive solution engineered specifically for the unique challenges of working with aluminum and other non-ferrous metals. In industrial environments, grinding soft metals often leads to wheel "loading" or clogging, where the metal adheres to the abrasive grain, rendering the wheel useless and generating excessive heat. Walter Surface Technologies has solved this problem with a proprietary formulation that resists clogging, ensuring consistent cut rates and extended wheel life even under heavy use.

Measuring 9 inches in diameter with a 1/4-inch thickness and 7/8-inch arbor, this Type 27 wheel is designed for heavy-duty stock removal on large surface areas. It is particularly valuable for fabrication shops handling aluminum structures, tanks, and trailers where efficiency is paramount. The wheel maintains its aggressive cutting action throughout its lifespan, reducing the frequency of wheel changes and keeping production lines moving.

Contamination-Free Surface Preparation

One of the critical features of the ALU™ line is its purity. Unlike many competitors that use waxes or lubricants to prevent clogging, the Walter 08L900 is manufactured without these additives. This is a significant advantage for welding operations. Waxes can contaminate the base metal, leading to porosity or weak welds if not meticulously cleaned with solvents like acetone. With the ALU™ wheel, the ground surface is clean and weld-ready immediately, eliminating an entire step in the surface preparation process and reducing chemical usage in the shop.

Cost-Effective Durability

While specialized for soft metals, this wheel does not compromise on durability. It offers an outstanding removal rate that rivals standard wheels used on steel, but with the specialized bond required for aluminum. By preventing the glazing effect, the wheel is utilized to its core, providing excellent value per cut and reducing overall abrasive costs for the facility.
