Walter SST Corecut 1-Inch Diameter x 1-Inch Depth Annular Cutter

Cut Cleaner, Faster Holes with Walter SST Corecut

For welders and fabricators, time is money, and hole preparation is often a bottleneck. The Walter 1" x 1" SST Corecut Annular Cutter (05A100) is built to speed up your workflow while delivering superior hole quality. Unlike traditional twist drills that require massive amounts of pressure and leave rough edges, this annular cutter removes material only at the periphery of the hole, ejecting a solid slug. This method requires less power and force, allowing you to drill large 1-inch diameter holes quickly and effortlessly using a magnetic drill.

What sets the Walter SST apart is its special bronze surface treatment. If you've ever struggled with bits overheating or getting stuck in stainless steel, this is the solution. The SST treatment acts as a lubricant barrier, drastically reducing heat buildup. This means the cutter stays sharper for longer, even in tough materials. The modern tooth design and cutter geometry are engineered to bite into the metal smoothly, reducing vibration and chatter. This stability not only protects your drill motor but also ensures that every hole is perfectly round and accurate.

This cutter is designed with the real-world needs of welders in mind. The universal shank fits most standard mag drills, so you can swap it into your existing setup with ease. The extra-large flutes clear chips out of the way fast, so you don't have to stop and clear the hole constantly. Whether you are drilling beam flanges for structural work or fabricating custom parts from aluminum plate, the Walter 05A100 gives you the reliability and speed you need to get the job done right the first time. Stop fighting with dull bits and upgrade to the efficiency of Walter Corecut technology.
