OVERVIEW

Grind Aluminum Without the Clog

Every welder knows the frustration of taking a standard grinding wheel to a piece of aluminum. Within seconds, the soft metal gums up the wheel, the cutting stops, and you are left just rubbing heat into the part. The Walter ALU™ Grinding Wheel changes the game. Designed specifically for the unique challenges of aluminum fabrication, this wheel refuses to clog. You get a fast, aggressive bite from the first spark to the nub, allowing you to rip through weld beads and bevel plates without constantly stopping to change wheels or dress the face.

Weld Immediately - No Acetone Needed
One of the biggest hassles in aluminum prep is the cleaning. Usually, you have to wipe everything down with acetone or other solvents to remove the waxes and lubricants that other grinding wheels leave behind. If you don't, you get porosity in your welds. The Walter ALU™ wheel is manufactured completely free of these contaminants. This means you can grind your joint and pick up your TIG torch or MIG gun immediately. There is no residue left on the metal that will mess up your arc or contaminate the puddle. It is a true "grind and weld" solution.

Built for the Shop
This 4-1/2 inch wheel fits your standard angle grinder with a 7/8" arbor. It is a Type 27 wheel, meaning it has a depressed center that lets you get in close and apply the pressure needed for heavy stock removal. Whether you are building boat hulls, truck boxes, or custom aluminum fixtures, the 08L450 gives you the performance you need to keep the job moving. It cuts cool, cuts fast, and lasts longer than the competition, saving you trips to the tool crib.

FAQ

No, the Walter ALU™ wheel is specifically formulated to resist loading and clogging, even on soft, gummy aluminum alloys.

No, the wheel is free of waxes and lubricants, so it leaves no residue that would require cleaning before welding.

This wheel features a standard 7/8" arbor, compatible with most 4-1/2" angle grinders.

While it physically can grind other metals, it is optimized for aluminum. Using it on harder metals like stainless steel may result in faster wear compared to wheels designed for stainless.

Always check the label on the wheel, but standard 4-1/2" grinding wheels are typically rated for approximately 13,300 RPM.

This is a Type 27 wheel, which has a depressed center, making it suitable for grinding at angles between 15 and 30 degrees.

It saves time in two ways: by maintaining a high removal rate without clogging (less downtime) and by eliminating the post-grind cleaning step.

Standard PPE for grinding is required, including a face shield, safety glasses, gloves, and hearing protection. Ensure the grinder guard is in place.
