Walter Carbide Core Cut Annular Cutter, 9/16-Inch x 2-Inch Depth, Universal Shank

Cut Faster and Last Longer on Tough Jobs

For professional welders and fabricators, time spent fighting with dull drill bits is time wasted. The Walter 05H309 9/16-inch Carbide Core Cut annular cutter is built to handle the heavy-duty reality of the job site. If you frequently work with stainless steel, you know how quickly it can destroy a standard HSS bit. This cutter is the solution. Equipped with extra-hard carbide tips, it slices through stainless, cast iron, and hard alloys without overheating or dulling prematurely. This means you can drill more holes per bit, saving you money on consumables and keeping your project moving forward without constant tool changes.

The 2-inch depth of cut is a game-changer for structural work. Whether you are piercing thick I-beams, drilling into heavy machinery frames, or fabricating pressure vessels, this cutter has the reach to get through in a single pass. The annular cutting action removes material only at the periphery of the hole, ejecting a solid slug. This requires significantly less horsepower and physical force than a traditional twist drill, reducing operator fatigue and wear on your magnetic drill motor. You get a clean, precise, burr-free hole every time, ready for bolting or welding immediately.

Compatibility is never an issue with the Walter 05H309. It features a universal shank that snaps securely into almost any magnetic drill, including popular brands with quick-connect or standard set-screw arbors. This "grab-and-go" versatility makes it an essential addition to any welder's toolbox. Whether you are working in the shop or out in the field on a remote install, you can rely on this cutter to perform. It is even designed to handle the shock of drilling into uneven or curved surfaces, giving you the confidence to tackle any fabrication challenge that comes your way.
