Walter SST+ Cobalt Drill Bit #30 Wire Gauge

The Welder's Choice for Stainless Steel

Every welder knows the struggle of drilling through stainless steel with a cheap bit—it overheats, dulls instantly, and work hardens the material, making the job nearly impossible. The Walter 01B530 SST+ Jobber Drill Bit (#30) is the solution to these headaches. Built specifically for the demands of metal fabrication, this bit eats through stainless steel, mild steel, and aluminum with aggressive speed and reliability. If you are fabricating custom parts, installing fixtures, or performing repairs, this is the bit you want in your drill.

The secret lies in the cobalt blend construction. Unlike standard bits that soften when they get hot, the SST+ maintains its hardness at high temperatures, allowing you to drill hole after hole without losing your edge. The 135° self-centering Speed Tip is a game-changer for portable drilling applications. You can place the tip exactly where you need the hole, pull the trigger, and it penetrates immediately—no center punch required, and no skidding across your workpiece. This precision is vital when working on expensive finished surfaces where a slip could mean a costly scratch.

Walter has also designed this bit to handle the torque and stress of hand-held drilling. The heavy-duty web construction resists snapping, while the back-tapered body prevents the bit from getting stuck or binding in the hole. Whether you are drilling rivets, pilot holes, or clearance holes on curved surfaces like pipe and tubing, the SST+ delivers clean, round holes every time. Stop wasting money on bits that burn out after two holes; upgrade to the Walter SST+ and experience the difference professional-grade tooling makes.
