Walter SST+ #18 Cobalt Jobber Drill Bit for Stainless Steel

Reliable Cobalt Drill Bits for Welding Fabrication

For welders and fabricators, preparing metal for joining is just as important as the weld itself. The Walter #18 SST+ Jobber Drill Bit is built to withstand the rigorous demands of the welding shop, offering unmatched durability when working with hard alloys. If you frequently work with stainless steel, you know that standard drill bits can dull almost instantly. The SST+ is crafted with a heavy-duty cobalt blend that resists the high temperatures generated when drilling hard metals, ensuring the cutting edge remains sharp hole after hole.

Precision is key in fabrication, and the Walter SST+ delivers with its innovative Speed Tip design. This self-centering feature prevents the bit from "walking" across the metal surface, allowing you to place holes exactly where they are needed without the extra step of using a center punch. This is a massive time-saver for on-site repairs or when working with portable drills in tight spaces. The #18 size (0.1695 inches) is a standard wire gauge size often used for tapping or specific rivet applications, making this a staple in any fabricator's toolbox.

Durability is further enhanced by the bronze SST surface treatment. This unique finish reduces friction, allowing the bit to cut more freely and with less heat generation. Combined with the High Flow flute geometry, which ejects metal chips efficiently, this bit prevents the work-hardening of stainless steel—a common headache for welders. The back-tapered body design is another subtle but critical feature, preventing the bit from getting stuck or binding when drilling through thick plates.

Stop wasting money on cheap bits that burn out halfway through the job. Upgrade to the Walter 01B518 SST+ Jobber Drill and experience the difference that professional-grade tooling makes in your fabrication workflow. From mild steel brackets to complex stainless assemblies, this drill bit provides the bite and longevity you need to keep your projects moving forward.
