Walter SST Core Cut Annular Cutter 5/8" x 2" Universal Shank

Fast, Clean Holes for Fabrication

For welders and fabricators, time spent prepping holes is time lost on the arc. The Walter 05E310 5/8" SST Core Cutter is built to speed up your workflow when working with structural steel or heavy plate. Unlike traditional twist drills that require pre-drilling and stepping up sizes, this annular cutter removes only the periphery of the hole, ejecting a solid slug. This method requires significantly less energy and allows you to drill large, clean holes in a single pass. The 2-inch depth capacity is perfect for drilling through thick I-beams, tubing, and plate stacks found in heavy construction and fabrication shops.

What sets this cutter apart is the "SST" bronze coating. If you've ever burned up a bit pushing through stainless steel, you know that heat is the enemy. The SST coating acts like a permanent lubricant, keeping the bit cooler and allowing it to slide through the metal with less drag. This means you can push harder and drill faster without destroying the cutting edge. The result is a smooth, accurate hole that is ready for bolting or welding immediately, with no jagged edges to grind down.

Designed with a universal shank, this cutter snaps easily into your existing magnetic drill or drill press setup. It is tough enough to handle the vibration and stress of on-site work while precise enough for shop fabrication. Whether you are framing a building, repairing heavy equipment, or fabricating custom mounts, the Walter SST Core Cutter ensures your holes are straight, true, and finished in record time.
