05A104 - SST Core Cut Annular Cutter, 1-1/4 in. x 1 in. Universal Shank

Drill Cleaner, Faster Holes on the Job Site

For professional welders and ironworkers, time spent fighting with a dull or binding drill bit is time lost. The Walter SST Core Cut Annular Cutter (1-1/4" x 1") is built to keep your fabrication projects moving smoothly. If you are tired of burning through bits when drilling into stainless steel or thick structural beams, this cutter is the solution. It features a unique bronze SST coating that acts as a high-performance lubricant, letting the cutter glide through metal rather than grinding against it. This means you can drill faster with less pressure, saving wear and tear on both your magnetic drill and your arms.

The 1-1/4 inch diameter is a common size for heavy-duty bolting applications, and the 1-inch depth of cut is perfect for standard plate and beam flanges. One of the biggest frustrations in the field is dealing with rough, jagged holes that need to be filed down before a bolt will fit. The Walter SST Core Cut is designed with a special tooth geometry that leaves a flawlessly smooth finish right out of the gate. You get a clean, round hole every time, eliminating the need for secondary grinding or reaming. This efficiency translates directly to higher productivity on the shop floor or at the installation site.

Versatility is essential when you are out in the field. This cutter comes with a universal shank, meaning it will snap right into almost any standard magnetic drill you have in your truck, including major brands like Hougen, Nitto, and others. Whether you are fabricating aluminum frames, erecting steel structures, or repairing heavy machinery, the Walter 05A104 gives you the reliability you need. The extra-large flutes clear chips out of the hole instantly, preventing the bit from jamming and overheating. Upgrade your drilling setup with a tool that works as hard as you do.
