Walter ALU 7-Inch Aluminum Grinding and Cutting Wheel Type 27

Stop Clogging and Start Welding

Every welder knows the frustration of grinding aluminum. You start a cut, and within seconds, your wheel is gummed up with silver paste. You end up pushing harder, generating more heat, and getting nowhere. The Walter ALU 7-inch Grinding Wheel (08L702) is the solution to that headache. Built specifically for soft metals, this wheel refuses to clog. It keeps cutting freely from the first spark to the nub, saving you money on wasted wheels and saving your sanity on the job site.

No Contamination, No Porosity
One of the biggest risks in aluminum welding is contamination. If you use a grinding wheel that relies on waxes or lubricants to stop clogging, you are smearing those contaminants right into the pores of the metal. When you hit that with a TIG torch or a MIG gun, you get porosity and failed X-rays. The Walter ALU wheel is engineered without any waxes or lubricants. It leaves a clean, bare metal surface that is ready to weld immediately. You can skip the acetone wipe-down in many cases and trust that your prep work won't ruin your weld.

Cut and Grind with One Wheel
Time is money, and swapping wheels takes time. At 1/8-inch thick, this wheel is the perfect hybrid. It is thin enough to slice through aluminum plate or pipe quickly, but it has the reinforced strength to handle side-loading for light grinding, deburring, and beveling. It is the ideal tool for notching pipe or prepping a joint. Instead of carrying a stack of cutting discs and a stack of grinding rocks, you can handle most of your prep work with this single, versatile wheel.

Built for the Grind
Walter is known for durability, and the ALU line is no exception. Even though it is designed for soft metals, the bond is tough enough to last through heavy use. Whether you are building boat hulls, repairing trailers, or fabricating custom aluminum tanks, the 08L702 gives you the bite you need without the loading you hate.
