Walter SST+ #40 Cobalt Jobber Drill Bit

Drill More Holes in Less Time

Fabricators and welders know that drilling through stainless steel can be a frustrating, tool-destroying process if you don't have the right equipment. The Walter SST+ #40 Jobber Drill Bit is built specifically to solve this problem. Whether you are prepping a chassis, installing hardware, or fabricating custom metalwork, this bit delivers the bite and stamina you need. Made with a heavy-duty cobalt blend, it resists the intense heat that burns up standard high-speed steel bits, giving you a tool that stays sharp longer and drills more holes per dollar.

The frustration of a drill bit wandering across your workpiece is a thing of the past with the SST+. Its self-centering Speed Tip allows you to start drilling instantly with pinpoint accuracy, even on round tubing or polished surfaces. You can leave your center punch in the toolbox and trust the bit to do the work. This feature is a massive time-saver for welders who need to drill multiple rivet or bolt holes in rapid succession. The 135-degree point angle is aggressive enough to cut quickly but robust enough to handle the shock of breaking through the backside of the material without chipping.

Walter has also designed this bit to run cooler and smoother. The special bronze SST coating acts as a lubricant and shield, preventing metal chips from welding to the bit—a common issue when drilling aluminum or gummy stainless grades. The high-flow flutes eject debris fast, so you aren't re-cutting chips, which keeps the cutting edge fresh. The body of the bit is slightly tapered from tip to shank, eliminating the friction that causes binding and snapping deep in a hole. When your project demands clean, accurate holes in tough materials, trust the Walter SST+ to get the job done right the first time.
