Walter SST+ Cobalt Jobber Drill Bit - Wire Gauge #57

Heavy-Duty Cobalt Drill Bit for Welders

When you are in the middle of a fabrication project, the last thing you need is a drill bit that snaps or dulls halfway through a piece of stainless steel. The Walter #57 SST+ Jobber Drill Bit is built specifically for the demands of professional welding and metalworking shops. Engineered with a heavy-duty cobalt blend, this bit is designed to cut through mild steel, stainless steel, and non-ferrous metals with aggressive speed and unmatched durability. It is the go-to choice for welders who need reliable tools that perform under pressure.

One of the standout features for fabrication work is the self-centering Speed Tip. In welding applications, you are often drilling in awkward positions or on rounded surfaces like pipes and tubing. Standard bits tend to wander, scratching the material and ruining the finish. The Walter SST+ bites immediately upon contact, allowing for precise drilling without the hassle of using a center punch. This saves you time on every hole and ensures your fit-up is accurate.

Durability is key in MRO and production environments. The bronze SST surface treatment and back-tapered body work together to reduce friction, which is the enemy of drill bit life. By keeping the bit cooler and preventing binding, Walter ensures that the 01B557 lasts significantly longer than generic bits, giving you more holes per dollar. Whether you are drilling out rivets, preparing pilot holes, or fabricating brackets, this drill bit delivers the torque-handling capability and cutting power necessary for professional results.

Why Welders Choose Walter SST+
