Walter SST Corecut 15/16-Inch x 3-Inch Annular Cutter

Drill Faster, Last Longer, Finish Cleaner

When you are out in the field or working on a heavy fabrication project, you need a mag drill bit that doesn't quit halfway through a thick plate. The Walter 15/16" x 3" SST Corecut Annular Cutter is built for welders and fabricators who demand speed and reliability. If you've ever struggled with bits burning up on stainless steel or getting stuck deep in a hole, this is the upgrade you need. The secret is in the bronze "SST" coating. It acts like a permanent lubricant shield, letting the cutter glide through metal with way less resistance. This means you don't have to lean on the drill as hard, and the bit stays cooler, keeping its edge sharp for hole after hole.

This specific cutter is designed for deep reach, handling materials up to 3 inches thick. It's perfect for drilling through stacked plates, heavy I-beams, or thick pipe walls. The flutes on the side are ground extra wide to throw chips out of the hole fast, so you don't have to stop and clear the bit constantly. Plus, the cut is so clean that you usually won't even need to grab a file or grinder to deburr the edges—just drill it and weld it.

Compatibility is never an issue with the Walter SST Corecut. It features a universal shank that snaps right into almost any magnetic drill press on the market. Whether you are drilling mild steel, aluminum, or tough stainless, this 15/16" cutter gives you the bite you need to get the job done efficiently. Stop wasting time changing dull bits and start cutting with the performance of Walter.
