Walter 44mm Carbide Tipped Annular Cutter 30mm Depth

Cut Clean Holes Fast in Stainless and Cast Iron

When you are out on a job site or in the fab shop, time is money, and a dull drill bit is a welder's worst nightmare. The Walter 44mm x 30mm Carbide Core Cut Annular Cutter is built to chew through the stuff that eats regular bits for breakfast. If you are working with stainless steel, cast iron, or hard alloys, this is the tool you want in your magnetic drill. Designed with extra-hard carbide inserts, it stays sharp longer and cuts faster, letting you punch through thick plate and pipe without slowing down.

Why choose carbide over standard HSS? It comes down to heat and hardness. Stainless steel work hardens quickly, which can destroy a standard bit in seconds. The Walter Carbide Core Cut handles that heat and keeps cutting. Its aggressive flute design clears chips out of the hole instantly, keeping the cutter cool and preventing binding. This means you can push your mag drill harder and get the job done quicker. Plus, because it's an annular cutter, you are removing less metal—just the ring around the edge—so you get a cleaner hole with less effort and less wear on your rig.

This cutter isn't just for flat plate, either. Its rugged construction makes it perfect for drilling into curved surfaces like large diameter pipe or uneven castings. You get a precise, round hole every time, with a finish so smooth you can often skip the grinder. Whether you are retrofitting structural steel or fabricating heavy-duty equipment, the Walter 05F144 gives you the reliability you need to keep the sparks flying and the project moving. Upgrade your drilling game with Walter's proven durability.
