Walter SST+ #39 Wire Gauge Drill Bit, Cobalt Blend, 135° Split Point

The Heavy-Duty Solution for Stainless Steel Drilling

Welders and metalworkers know that drilling stainless steel is one of the toughest challenges in the shop. Standard bits burn up, snap, or work-harden the material, leading to frustration and wasted time. The Walter 01B539 SST+ Jobber Drill Bit (#39) is built specifically to solve these problems. This isn't just another drill bit; it is a high-performance cutting tool designed to withstand the rigors of the welding environment. With a diameter of 0.0995 inches (#39 Wire Gauge), it is perfectly sized for precision pilot holes, tapping preparation, or rivet installations in heavy-gauge metal.

The secret to the SST+ bit's durability lies in its cobalt-infused high-speed steel body. This material blend allows the bit to resist the intense heat generated when drilling hard metals. For a welder, this means you can drill through stainless steel flanges, brackets, and sheets without the tip melting or dulling prematurely. The 135-degree split point is another critical feature for fabrication work. It bites into the metal instantly upon contact. If you are working on a vertical surface or trying to drill into a curved pipe, this bit stays exactly where you put it, ensuring your holes are precise and your alignment is perfect every time.

Efficiency is key in MRO and fabrication. The Walter SST+ features a unique Bronze SST surface finish that helps shed heat and reduce friction. This allows for faster drilling speeds and cleaner holes with fewer burrs to grind off later. The heavy-duty web construction adds rigidity to the bit, preventing the snapping that often occurs with smaller wire-gauge bits under torque. This structural integrity makes it suitable for use with powerful hand drills often found on job sites.

Stop wasting money on cheap bits that fail after three holes. Upgrade to the Walter SST+ series for your toolbox. Whether you are drilling out broken bolts, prepping for fasteners, or fabricating custom parts, the 01B539 delivers professional performance. It works exceptionally well on mild steel, aluminum, and stainless, making it a versatile "go-to" bit for any metalworking project. Experience the difference that a premium, purpose-built cutting tool makes in your daily workflow.
