Walter 45mm TCT Annular Cutter 55mm Depth

Cut Through Stainless Like Butter

If you have ever burned through three HSS bits trying to drill a single hole in a thick stainless steel plate, you know the frustration. The Walter 05F245 Carbide Core Cut is the solution you have been looking for. This 45mm (approx. 1-3/4 inch) annular cutter is built with ultra-tough carbide teeth that eat through hard metals without complaining. It is designed for the welder who needs to get the hole drilled right the first time, so you can move on to fitting and welding without downtime.

This cutter features a 55mm depth of cut, giving you plenty of reach for thick structural beams, heavy plating, or stacked materials. Unlike standard twist drills that require huge amounts of pressure and leave a mess, this annular cutter removes only the outer ring of metal, ejecting a solid slug when you are done. This means less wear and tear on your mag drill and much faster drilling times. The geometry of the cutter is specifically tuned to clear chips fast, which keeps the bit cool—a critical factor when you are working with stainless steel or cast iron to prevent work-hardening.

The Walter 05F245 is also forgiving on the job site. Its design helps it start clean, even on curved surfaces or weathered steel, reducing the chance of the bit walking or chattering. Whether you are retrofitting structural steel, repairing heavy machinery, or fabricating custom parts, this tool gives you the confidence to tackle large-diameter holes. It fits standard magnetic drill arbors, making it a plug-and-play upgrade for your existing setup. Stop fighting your drill press and let the carbide do the work.

Built for the Grind

We know that tools on a welding rig take a beating. The Walter Carbide Core Cut is constructed to withstand the rigors of daily use. It stays sharp longer than the competition, meaning fewer tool changes and more holes per dollar. When you have a deadline to meet and heavy metal to drill, trust Walter to get you through the thickest plate.
