Walter SST Core Cut Annular Cutter 1-1/16 Inch x 3 Inch Depth

Precision Fabrication with Walter 05A701 Core Cutters

For professional welders and fabricators, the quality of hole preparation can make or break a project. The Walter 05A701 SST Core Cut Annular Cutter is designed to deliver flawless holes in a single pass, making it an essential tool for structural steel erection, custom fabrication, and heavy manufacturing. With a 1-1/16 inch diameter and a deep 3-inch cutting capacity, this cutter allows you to penetrate thick sections of steel, stainless steel, and aluminum with unmatched speed and accuracy.

Traditional twist drills often require pre-drilling or step-drilling and can leave rough, burred edges that require time-consuming cleanup before welding or bolting. The Walter SST Core Cut eliminates these steps. Its advanced tooth geometry and SST (Special Surface Treatment) work together to slice through metal efficiently, leaving a smooth, burr-free finish that is ready for immediate assembly. The reduction in friction provided by the SST coating is particularly beneficial when working with work-hardening materials like stainless steel, preventing the bit from binding or overheating.

Versatility is key in a busy shop or on a job site. The 05A701 features a universal shank, making it compatible with the majority of magnetic drills on the market today. This means you can grab this cutter and get to work without worrying about shank compatibility issues. The cutter's robust design also includes extra-large flutes for superior chip clearance, ensuring that you can maintain optimal feed rates without bogging down the machine.

Whether you are fabricating beam connections, installing heavy machinery, or working on custom pipe supports, the Walter SST Core Cut offers the reliability and performance you need. It turns the arduous task of drilling large, deep holes into a quick, precise operation, allowing you to focus on what you do best: welding and fabricating high-quality metal structures.
