Walter SST+ Cobalt Stub Drill Bit #38 Wire Gauge

The Welder's Choice for Tough Sheet Metal Work

When you are prepping a chassis, drilling out rivets, or fabricating custom sheet metal parts, you need a drill bit that won't snap under pressure. The Walter 01J038 #38 SST Stub Drill is built for the harsh reality of the welding shop. Unlike standard length bits that can flex and break when you lean into them, this stub bit features a short, robust profile that transfers force directly to the cutting edge. This makes it incredibly resistant to breakage, saving you money and frustration on the job.

Drilling stainless steel is notorious for burning up standard bits, but the Walter SST+ series is up to the task. Infused with cobalt, these bits resist the intense heat generated by work-hardening metals. The #38 wire gauge size (0.1015") is precise, and the bronze surface treatment helps shed chips quickly to keep the bit cool. For welders working on automotive repairs or structural fabrication, this means you can drill more holes in less time without constantly stopping to sharpen or replace your tooling.

Accuracy is critical when you only have one shot at a hole. The self-centering split point on this bit grabs the metal instantly. You won't have to worry about the bit skating across your workpiece and scratching the finish. It bites in hard and cuts fast. From mild steel to non-ferrous metals and stainless, the Walter 01J038 is a versatile workhorse that belongs in every welder's toolbox.

Why Welders Prefer SST Stub Drills

• No Walking: The split point tip centers itself, perfect for drilling out spot welds or starting holes on curved pipe.
• Breakage Resistant: The compact length handles the side-load and pressure of hand drilling better than jobber bits.
• Versatile Performance: Cuts through stainless, aluminum, and mild steel with equal ease.
