Walter SST+ #9 Cobalt Jobber Drill Bit for Stainless Steel

Drill Stainless Steel Faster with Walter SST+

Every welder knows the frustration of grabbing a drill bit to make a hole in a stainless steel bracket, only to have the bit smoke, squeal, and burn out before it even breaks the surface. The Walter SST+ #9 Jobber Drill Bit (01B509) is the solution to that headache. Built for the fabrication shop and the job site, this bit eats through stainless steel, mild steel, and aluminum without work-hardening the material. If you are fabricating custom parts, installing fixtures, or prepping for a tap, this is the reliable bit you need in your index.

The secret lies in the heavy-duty cobalt blend. Stainless steel gets incredibly hot when you drill it, and that heat kills standard black oxide bits instantly. The SST+ cobalt formula loves the heat, staying sharp long after other bits have failed. This means you spend less time swapping out dull bits and more time getting work done. Plus, the unique bronze coating helps the bit slide through the metal, reducing the force you need to apply.

One of the best features for welders is the self-centering "Speed Tip." When you are working on a piece of round tubing or trying to drill a hole in an awkward position, you don't always have a free hand to use a center punch. This bit bites instantly—no walking, no skating across the surface. It digs in exactly where you put it. The aggressive flute design pulls chips out fast, keeping the hole clean and the bit cool. Whether you are using a hand drill or a drill press, the Walter SST+ #9 gives you the performance you need to tackle tough jobs with confidence.
