08L705 - Walter ALU 7-Inch Aluminum Grinding Wheel with Threaded Hub

Professional Grade Aluminum Grinding Solution

The Walter ALU Grinding Wheel (08L705) is a specialized abrasive tool engineered specifically for the unique challenges of working with aluminum and other soft, non-ferrous metals. In industrial fabrication, grinding aluminum is notoriously difficult because the material has a low melting point and tends to "load" or clog the surface of standard grinding wheels. Once a wheel is clogged, it stops cutting, generates excessive heat, and becomes dangerous to use. Walter Surface Technologies has solved this problem with their proprietary ALU formulation.

This 7-inch wheel features a coarse A24 grit and a soft bond that allows the abrasive grains to break away at the optimal rate, exposing fresh, sharp grain constantly. This self-sharpening action prevents the aluminum from adhering to the wheel face. As a result, operators experience a continuous, aggressive removal rate without having to stop and dress the wheel or apply friction-reducing lubricants like wax or paraffin. This not only saves time but also keeps the workpiece cleaner, reducing the need for post-process cleaning before welding or finishing.

The 08L705 comes equipped with a 5/8-11 threaded arbor, allowing for quick "spin-on" mounting to standard 7-inch angle grinders. This hub design increases safety and reduces vibration compared to standard non-threaded wheels. With a maximum rating of 8,600 RPM, this Type 27 depressed center wheel is ideal for heavy-duty stock removal, weld blending, and edge chamfering on aluminum structures, trailers, and marine components.

Key Benefits for Fabricators

• Non-Loading Technology: Grind aluminum continuously without the wheel glazing over.
• Lubricant Free: Eliminates the need for messy waxes that can contaminate welds.
• High Productivity: Fast removal rates reduce labor time on large projects.
• Quick Change: Integrated hub reduces downtime during wheel changes.
