01D615 - Walter 11.50Mm Sst Drill Bit

The Ultimate Drill Bit for Tough Metal

For welders and fabricators, time is money, and a dull drill bit is a major bottleneck. The Walter SST+ 11.50mm Drill Bit is built to solve the frustration of drilling through hard metals. If you work with stainless steel, you know how easily it can work-harden if your bit slips or rubs instead of cuts. The SST+ is designed with a heavy-duty cobalt blend that bites instantly and keeps cutting, ensuring you get through the material before it hardens up. This means fewer burned-out bits and less downtime swapping tools in the middle of a job.

One of the standout features for daily shop use is the self-centering 135° split point. When you are working on a curved surface, like a pipe or a round tube, standard bits tend to "walk" across the metal, scratching the finish and ruining your alignment. The Walter SST+ grabs the metal immediately, allowing you to drill exactly where you need to without a pilot hole or a center punch. This precision is crucial when preparing materials for fit-up or installing hardware on finished assemblies.

Durability is at the core of this bit's design. The bronze SST coating isn't just for looks; it acts as a heat shield and lubricant, helping the bit run cooler and smoother. The unique flute design pulls chips out of the hole fast, which keeps the heat down and prevents binding. Whether you are drilling out broken bolts, prepping holes for tapping, or fabricating heavy structural brackets, the Walter 01D615 11.50mm bit gives you the aggressive performance you need to get the job done right the first time. It is a rugged, reliable tool that belongs in every welder's toolbox.
