Walter SST Corecut 9/16-Inch x 1-Inch Universal Shank Annular Cutter

Get Clean Holes Fast with Walter Annular Cutters

When you are out in the field or working on a tight deadline in the shop, you need a cutter that bites hard and lasts long. The Walter 9/16" SST Corecut Annular Cutter (SKU: 05E009) is built for welders and fabricators who demand performance. Whether you are drilling holes for framing, mounting machinery, or fabricating custom parts, this cutter is designed to fit your magnetic drill and power through metal without slowing down. The 1-inch depth of cut is perfect for standard plate and tubing applications found in most welding projects.

The secret to the SST Corecut's performance is in the metal itself. Walter uses a special Super Speed Technology heat treatment that makes these cutters tougher than standard high-speed steel bits. This means you can drill through stainless steel without burning up the bit halfway through the job. If you have ever struggled with bits dulling instantly on hard metals, the SST Corecut is the upgrade you need. Plus, the Universal Shank means you don't have to worry about compatibility; it snaps right into your mag drill, whether you are running a Hougen, a Unitec, or another common brand.

Using an annular cutter like the 05E009 is also about working smarter, not harder. Because it cuts a ring and ejects a slug, you aren't wasting power turning the whole hole into chips. This results in a much faster cut with less pressure required on the drill handle. The holes come out clean, round, and virtually burr-free, so you can drop your bolts in immediately without wasting time grabbing a grinder or a file. Upgrade your drilling game with Walter's trusted quality and keep your fabrication line moving smoothly.

Why Welders Choose Walter SST:

• Universal Fit: Works with the magnetic drill you already own, no adapters needed for most models.
• Stainless Ready: Tough enough for stainless steel, which means it cuts mild steel like butter.
• Time Saver: No pilot holes needed—just center the pin and drill. No deburring needed after the cut.
