Walter SST+ 27/64" Cobalt Drill Bit for Stainless Steel

The Drill Bit That Won't Quit on Stainless

Every welder knows the frustration of a drill bit that dulls the second it touches stainless steel. The Walter 01A527 SST+ 27/64" Drill Bit is built to solve exactly that problem. If you are fabricating custom parts, repairing heavy equipment, or working on a pipeline, this is the bit you reach for when you need a hole drilled right the first time. It uses a special cobalt blend that handles the heat of drilling hard metals without losing its temper, meaning you spend less time sharpening or swapping bits and more time welding.

One of the standout features for fabricators is the bit's ability to bite into the metal instantly. Thanks to its self-centering design, you can drill directly into round stock, pipes, or curved surfaces without the bit "walking" or skating across the metal. This saves you the hassle of center punching every single hole. The "high flow" flute design is another game-changer; it pulls chips out of the hole fast, keeping the bit cooler and preventing that dreaded squeal of a burning tip.

Whether you are running a hand drill on a job site or using a drill press in the shop, the Walter SST+ gives you the heavy-duty performance required for professional fabrication. It cuts clean, stays sharp, and powers through mild steel, aluminum, and stainless alike. Don't let a cheap bit slow down your production—upgrade to the SST+ and feel the difference in every cut.
