Walter 20mm Carbide Tipped Annular Cutter 55mm Depth

Cut Through Stainless Like Butter

If you have ever burned through stack after stack of HSS bits trying to drill a clean hole in stainless steel or cast iron, the Walter 20mm x 55mm Carbide Core Cut Annular Cutter is the solution you have been waiting for. Designed for the professional welder and fabricator who demands reliability, this cutter is built to eat through the hardest metals in the shop. Forget about the chatter, the smoke, and the constant sharpening; this carbide-tipped beast stays sharp and cuts cool, even when you are pushing it to the limit on a heavy structural job.

The magic lies in the extra-hard carbide inserts. Unlike standard bits that grind away the material, these precision-ground tips slice through the periphery of the hole, removing less material and requiring significantly less horsepower and downward pressure. This means you can punch a 20mm hole through 55mm thick plate without fighting the drill. The specialized flute design ejects chips rapidly, preventing them from clogging the cut and overheating the bit—a common killer of tools when working with gummy materials like aluminum or work-hardening stainless steel.

This cutter isn't just for perfect, flat steel plates either. Its robust design makes it ideal for drilling into uneven surfaces, pipes, and curved materials where other bits might walk or break. Whether you are retrofitting structural beams on a job site or fabricating custom heavy machinery parts in the shop, the 05F220 gives you the confidence to tackle any material. It fits standard magnetic drills, making it a plug-and-play upgrade for your existing setup.

Stop wasting time and money on inferior cutters that can't handle the heat. Upgrade to the Walter Carbide Core Cut and experience the difference that professional-grade tooling makes. You will get cleaner holes, faster cycle times, and a tool that lasts longer, letting you focus on laying down perfect welds rather than fighting with your drill press. It is the ultimate accessory for any serious metalworker dealing with tough alloys.
