Walter SST Corecut 7/16-Inch x 2-Inch HSS Annular Cutter with Universal Shank

Fast, Clean Holes for Professional Fabrication

When you are out on a job site or working in the fab shop, time is money, and the quality of your prep work determines the quality of your weld. The Walter 7/16" x 2" SST Corecut Annular Cutter is built to help you blast through heavy steel and stainless without slowing down. If you are tired of fighting with large twist drills that bind up, overheat, or require a massive amount of pressure to feed, this annular cutter is the upgrade you need. It cuts a clean, precise 7/16-inch hole by removing only the outer ring of metal, leaving a solid slug. This means you can drill faster with less physical effort and less wear on your mag drill motor.

This specific cutter features a 2-inch depth of cut, giving you the reach to handle thick I-beams, tubing, and plate stacks in a single pass. The universal shank is a huge time-saver; whether your mag drill takes a standard Weldon flat shank or a Nitto style connection, this bit slides right in and locks tight. It is designed to handle the heat generated by drilling stainless steel, staying sharp longer so you aren't constantly swapping out bits in the middle of a project. The result is a hole that is virtually burr-free, often eliminating the need for secondary reaming or deburring before you drop in a bolt or start welding.

Walter Surface Technologies is known for making tools that withstand the abuse of real-world welding environments. The SST Corecut is no exception. It tracks straight, starts easily without walking, and ejects chips efficiently to keep the cut cool. Whether you are erecting structural steel, modifying truck frames, or building custom machinery, having a reliable cutter like the 05E307 in your kit ensures you can make the holes you need, exactly where you need them, every single time.
