Walter SST+ 7/16" Cobalt Drill Bit for Stainless Steel

Tough Bits for Tough Metals

As a welder, you know that drilling through stainless steel can be a nightmare with the wrong tools. Burnt tips, snapped bits, and wandering points can ruin your workflow. The Walter 7/16" SST+ Drill Bit is built to solve these problems. Infused with a powerful cobalt blend, this bit is designed to withstand the intense heat generated when drilling hard metals, ensuring it stays sharp longer than standard high-speed steel bits. It is the reliable partner you need when prepping materials for a weld or fabricating custom parts.

Speed and accuracy matter on the job site. The SST+ features a unique "High Flow" flute design that pulls chips out of the hole quickly, allowing you to drill faster without bogging down. The bronze SST surface treatment helps the bit glide through metal, reducing the friction that causes overheating. Whether you are using a stationary drill press in the shop or a portable hand drill in the field, this bit delivers consistent performance.

Stop struggling with walking bits. The Walter SST+ is designed to bite into the material immediately, even on round surfaces like pipe and tubing, making it perfect for fitting and fabrication work. Its heavy-duty fully ground body resists breakage, giving you the confidence to lean into the cut. From mild steel to aluminum and stubborn stainless, this 7/16" drill bit is an essential addition to any welder's toolbox.
