Walter SST+ Cobalt Jobber Drill Bit #43 Wire Gauge

The Ultimate Drill Bit for Stainless Steel Fabrication

For professional welders and fabricators, drilling through stainless steel can often be a frustrating, tool-destroying task. The Walter 01B543 SST+ Jobber Drill Bit (#43) is the solution you have been looking for. Designed specifically to overcome the challenges of hard metals, this drill bit is a must-have for any serious metalworker's toolbox. When you are working on a critical project, you cannot afford to waste time with bits that burn out, snap, or wander. The Walter SST+ is built with a heavy-duty cobalt blend that resists the intense heat generated during drilling, ensuring that the cutting edges stay sharp hole after hole.

One of the standout features for welders is the "Speed Tip" design. In fabrication, you are often drilling on materials that aren't perfectly flat—like pipes, tubes, or curved structural members. Standard bits tend to wander or "walk" off the mark, scratching the finish and ruining precision. The Walter 01B543 features a self-centering tip that grabs the metal instantly, allowing you to drill accurate holes on round surfaces without needing a center punch. This feature alone saves significant time during fit-up and assembly.

The geometry of the bit is optimized for speed and ease of use. The "High Flow" flutes are designed to pull chips out of the hole quickly and efficiently. This is crucial when working with stainless steel, as trapped chips cause heat buildup that can work-harden the metal, making it nearly impossible to drill further. With the SST+, chips flow out smoothly, keeping the cutting action cool and aggressive. The bronze SST surface treatment adds an extra layer of lubricity, helping the bit glide through the metal with less force required from the operator.

Whether you are drilling rivet holes, pilot holes, or clearance holes in mild steel, aluminum, or heavy-gauge stainless, the Walter 01B543 delivers professional results. It is compatible with all portable drilling applications, making it perfect for on-site repairs and installation work. Stop struggling with inferior bits that dull after a few uses. Upgrade to the Walter SST+ and experience the difference that premium cobalt tooling makes in your daily fabrication work.
