08L700 - Walter ALU Type 27 Aluminum Grinding Wheel 7-Inch

Optimized Abrasive Solution for Aluminum Fabrication

The Walter ALU™ Grinding Wheel (SKU: 08L700) is a specialized abrasive engineered specifically for the challenges of working with aluminum and other non-ferrous metals. In standard grinding operations, soft metals tend to clog or "load" the face of the wheel, causing friction, excessive heat buildup, and a rapid loss of cutting efficiency. The ALU™ line utilizes a proprietary abrasive formulation that resists this loading effect, ensuring a consistent, aggressive cut rate throughout the lifespan of the wheel.

A critical feature of the 08L700 is its purity. It is manufactured completely free of waxes and lubricants. In many industrial applications, standard aluminum-specific wheels rely on additives to prevent clogging, but these additives can leave a residue on the metal surface. If not removed with solvents or cleaners, this residue often leads to porosity and defects in subsequent welds. By eliminating these contaminants, the Walter ALU™ wheel allows operators to grind and immediately weld, significantly streamlining the fabrication workflow and reducing consumable costs associated with cleaning agents.

This 7-inch wheel features a 1/4-inch thickness and a standard 7/8-inch arbor, making it compatible with most heavy-duty angle grinders. The Type 27 depressed center profile is ideal for aggressive stock removal, weld leveling, and edge beveling. For industrial MRO and fabrication shops dealing with aluminum structures, tanks, or marine vessels, this wheel provides a high-performance solution that balances speed, safety, and weld quality.
