Walter ZIP ALU 4.5 Inch Aluminum Cutting Disc 5-Pack

The Welder's Choice for Clean Aluminum Cuts

Every welder knows the frustration of prepping aluminum. You grab a standard cutting wheel, and within seconds, it's gummed up with soft metal, vibrating dangerously and refusing to cut. Enter the Walter ZIP ALU™ 4-1/2" Cutting Wheel, your new best friend for aluminum fabrication. This 5-pack (11U042V) is designed to keep you cutting smoothly so you can get to welding faster. Whether you are building custom boat hulls, repairing aluminum trailers, or fabricating fuel tanks, these wheels deliver the clean, cool cuts that high-quality aluminum welding demands.

The magic lies in the non-clogging technology. Aluminum is sticky and heat-sensitive, but the ZIP ALU™ wheel is formulated to resist loading. This means you get a straight, fast cut every time without having to stop and swap out a glazed wheel. The 3/64-inch thickness is the sweet spot for angle grinders—thin enough to slice through plate and tubing like butter, but tough enough to handle the rigors of the shop. Because it cuts so freely, it puts less strain on your grinder's motor and, more importantly, less strain on your arms and wrists.

Cleaner Cuts, Better Welds
Contamination is the enemy of a good TIG or MIG weld. Using the wrong abrasive can embed impurities into the base metal, leading to porosity and failed inspections. Walter's ZIP ALU™ is manufactured to cut cleanly without transferring contaminants that ruin your weld puddle. The result is a bright, burr-free edge that often requires little to no secondary filing or grinding before you strike an arc.

This convenient 5-pack ensures you have plenty of stock for the job at hand. Compatible with any standard 4-1/2" angle grinder with a 7/8" arbor, these wheels are a must-have upgrade for any shop working with non-ferrous metals. Stop fighting your tools and start cutting with the precision of Walter Surface Technologies.
