Walter SST 3/16-Inch Cobalt Jobber Drill Bit with Quick Shank

Stop Slipping and Start Drilling with Precision

Every welder knows the frustration of a drill bit spinning in the chuck just as you apply pressure to a tough piece of steel. The Walter 3/16" SST Jobber Drill Bit (01A012) solves this problem once and for all with its exclusive Quick Shank design. The shank features engineered flats that lock securely into your drill's jaws, ensuring 100% power transmission from your tool to the work surface. Whether you are using a heavy-duty corded drill or a portable cordless unit, this bit stays put, allowing you to power through mild steel, aluminum, and stainless steel with confidence.

Beyond the shank, the cutting performance of this bit is legendary in the trade. It is manufactured from a premium cobalt blend, which gives it the heat resistance needed to tackle hard metals without dulling prematurely. The "Speed Tip" is a game-changer for fabrication work; it is self-centering, meaning it won't "walk" or wander across the metal when you start drilling. This is incredibly useful when you are trying to drill into round stock, pipe, or tubing where standard bits often slide off the mark.

This bit is designed to make your life easier and your work faster. The back-tapered body design reduces drag, preventing the bit from binding in the hole, while the bronze surface treatment helps clear chips efficiently. It is particularly effective for drilling thin gauge sheet metal and multi-layer materials, producing clean, round holes with minimal burring. If you are looking for a drill bit that lasts longer, grips tighter, and drills faster, the Walter SST with Quick Shank is the upgrade your toolbox needs.
