OVERVIEW

Grind Aluminum Without the Clog – Walter ALU™ Series

Every welder knows the frustration of grinding aluminum. You start with a fresh wheel, and within seconds, the soft metal gums up the face of the disc. You stop cutting, you start generating excess heat, and you end up throwing away a wheel that should have lasted hours. The Walter ALU™ Grinding Wheel (08L455) is the solution to this headache. Designed specifically for soft metals, this wheel refuses to clog. It keeps cutting aggressively from the first spark to the last, saving you money on consumables and saving you time on the job.

Built for Speed and Convenience
This 4-1/2 inch wheel comes ready to work with a built-in 5/8"-11 threaded hub. No more fumbling with flange nuts or looking for a pin wrench—just spin it onto your grinder and get to work. The 1/4 inch thickness gives you the durability needed for heavy grinding, beveling, and taking down heavy welds. Whether you are building aluminum boat hulls, repairing truck trailers, or fabricating custom architectural pieces, this wheel delivers the fast removal rate you need to stay profitable.

Superior Performance on Non-Ferrous Metals
While it can handle steel, the Walter ALU™ shines when the material gets soft. Its unique composition lubricates the cut without leaving messy residues like wax or grease sticks, which is critical if you plan to weld over the ground area immediately. A clean grind means a cleaner weld and fewer porosity issues down the line. The A24 grit bites hard into the material, removing stock effortlessly so you don't have to lean on the grinder. Less pressure means less heat buildup and less fatigue at the end of the shift.

Upgrade your abrasive game with Walter Surface Technologies. Known for their premium quality and consistency, Walter wheels are balanced perfectly to run smooth and true. Don't let clogged wheels slow down your production—switch to the 08L455 ALU™ wheel and experience the difference of an abrasive actually designed for the metal you are working on.

FAQ

It is primarily designed for grinding aluminum and other non-ferrous metals without clogging, though it can also be used on steel and stainless steel.

No, this wheel features a 5/8"-11 threaded hub (spin-on), so it mounts directly to the grinder spindle without a separate flange nut.

This wheel has an A24 grit rating, which is a coarse grit designed for fast material removal.

No, the Walter ALU wheel is formulated to cut freely without the use of waxes or lubricants that typically cause contamination and porosity in subsequent welds.

The wheel measures 4-1/2 inches in diameter and is 1/4 inch thick.

Standard discs 'load up' or clog with soft aluminum, stopping the cutting action. The ALU wheel is impregnated with a formulation that prevents the metal from sticking to the abrasive.

While the specific max RPM should always be checked on the wheel label itself, standard 4-1/2" Type 27 reinforced wheels are typically rated for approximately 13,300 RPM.

The manufacturer standard package quantity is 10 wheels, though they may be sold individually depending on the retailer.
