Walter SST Core Cut Annular Cutter 1-15/16 Inch x 1 Inch Depth

Heavy-Duty Hole Cutting for Fabricators

When you are out in the field or in the shop fabricating structural steel, you need a mag drill bit that cuts fast and doesn't quit halfway through a beam. The Walter 05A115 SST Core Cut Annular Cutter (1-15/16" x 1") is built for exactly that kind of reliability. If you have ever struggled with bits that overheat, bind up, or dull instantly when hitting a hard spot, you will appreciate the difference the SST technology makes. "SST" stands for Super Speed Tip, which basically means this cutter has a slick, specially treated surface that sheds chips and resists heat better than standard bits. This allows you to push through steel, stainless, and aluminum faster while keeping the bit cool.

One of the biggest frustrations for welders is dealing with the mess left behind by inferior drill bits. The Walter SST Core Cut is designed with a unique tooth geometry that slices through metal rather than tearing it, leaving you with a clean, burr-free hole that is ready for bolting or welding immediately. No more wasting time with a grinder or file to clean up rough edges. The 1-inch depth of cut is perfect for standard plate and structural tubing, covering the majority of fabrication needs.

Compatibility is also key when you are sharing tools or moving between machines. This cutter features a universal shank, meaning it will fit securely into almost any magnetic drill press you have on the truck, whether it uses a Weldon shank system or a quick-connect style. The extra-large flutes help clear out those long, stringy chips that tend to jam up other cutters, especially when drilling aluminum. Whether you are erecting steel frameworks, repairing heavy equipment, or doing custom fabrication, the Walter 05A115 gives you the performance you need to get the holes drilled and the job done right.
