Walter SST Core Cut Annular Cutter - 9/16 in Diameter x 1 in Depth

Cut Cleaner, Drill Faster, Last Longer

Stop fighting with dull bits and overheated tools. The Walter 05A009 SST Core Cut Annular Cutter (9/16" x 1") is built for welders and fabricators who need to punch holes in steel and move on to the next job. If you are using a magnetic drill, you know that speed and chip clearing are everything. This cutter features Walter's special bronze SST (Super Speed Tip) coating, which acts like a shield against heat. Because it runs cooler, it stays sharper for longer, even when you are drilling through tough stainless steel or structural plate. No more burning up bits halfway through a project.

The geometry of this cutter is designed for the real world. It has extra-large, fully ground flutes that eject chips fast. This means you don't have to constantly back the bit out to clear debris, and you get a smooth, clean hole every single time. The finish on the cutter itself is polished to perfection, eliminating the rough spots where metal tends to stick and weld itself to the tool. The result is a hole so clean it often doesn't need deburring, saving you an extra step in your fabrication process.

Compatibility is never an issue with the Walter SST Core Cut. It comes with a universal shank that fits securely into almost any standard magnetic drill press or stationary machine. Whether you are framing up a building, repairing heavy equipment, or fabricating custom parts, this 9/16-inch cutter handles aluminum, steel, and stainless with ease. It’s a tough, reliable bit that works as hard as you do, ensuring that your holes are precise and your workflow stays uninterrupted.
