11U152 - Walter ZIP ALU 5-Inch Type 27 Aluminum Cutting Wheel

High-Performance Cutting for Non-Ferrous Metals

The Walter 11U152 ZIP ALU™ is a specialized abrasive cutting wheel engineered to address the unique challenges of working with aluminum and other non-ferrous metals. Standard abrasive wheels often fail when applied to soft, ductile metals because the material melts and adheres to the abrasive grains—a process known as "loading" or "clogging." Once a wheel loads, friction increases drastically, cutting stops, and the risk of wheel breakage rises. The ZIP ALU™ formulation utilizes a unique abrasive blend that resists this adhesion, ensuring the wheel remains free-cutting throughout its lifespan.

Type 27 Depressed Center Design

This specific model features a Type 27 depressed center configuration. Unlike flat Type 1 wheels, the Type 27 shape features a raised hub area. This design offers two distinct advantages: it allows the locking nut to be recessed, enabling flush cutting against surfaces without interference, and it provides increased rigidity to the wheel center. This added stiffness is particularly beneficial when precise control is required during the cut. With a 5-inch diameter and a standard 7/8-inch arbor, it is compatible with most industrial angle grinders.

Efficiency and Durability

Measuring just 3/64 inches in thickness, the 11U152 removes minimal material, which translates to less heat generation and faster cutting speeds. Heat management is critical when working with aluminum to prevent the material from softening and deforming. The cool-cutting action of the ZIP ALU™ preserves the integrity of the workpiece while extending the life of the wheel itself. Although specifically optimized for aluminum, this versatile tool is also capable of cutting ferrous metals effectively, making it a flexible addition to any fabricator's toolkit. It represents a premium solution for MRO professionals seeking to maximize productivity and safety in metal cutting operations.
