Walter SST Core Cut Annular Cutter 1-3/8 Inch x 2 Inch Universal Shank

Reliable Mag Drill Bits for Professional Fabricators

For welders and fabricators, time is money, and a dull or broken drill bit can bring a project to a grinding halt. The Walter 05E406 1-3/8" x 2" SST Core Cut Annular Cutter is built to keep you working efficiently. This cutter is designed to fit the most common magnetic drills used in the field thanks to its universal shank design. Whether you are drilling holes for beam connections, pipe flanges, or custom fabrication parts, this cutter delivers clean, precise holes without the struggle associated with traditional twist drills. The 2-inch depth of cut allows you to penetrate thick plate and structural members in a single pass.

What sets this cutter apart is the special Bronze SST surface treatment. If you have ever struggled with bits overheating and burning out when drilling stainless steel or thick aluminum, this is the solution. The SST coating acts as a lubricant and heat shield, drastically reducing friction as the cutter rotates. This means the bit stays cooler, the cutting edges stay sharper, and you can drill faster with less feed pressure. The result is a smooth hole with minimal burr, often saving you the step of having to deburr or ream the hole before inserting a bolt.

The 05E406 also features deep, ground flutes that eject metal chips quickly. Efficient chip removal is vital for preventing the cutter from binding or jamming deep in the hole. With the Walter SST Core Cut, chips flow out easily, allowing the cutter to do its job without interruption. From structural steel erection to shop fabrication, this tool is tough enough to handle daily abuse while delivering the precision required for high-quality welding and assembly work. Upgrade your mag drill kit with a cutter that lasts longer and cuts faster.
