Walter SST+ Cobalt Jobber Drill Bit, Wire Gauge #25

The Welder's Choice for Stainless Steel

For professional welders and fabricators, drilling through stainless steel can often be a frustrating bottleneck in the fabrication process. The Walter 01B525 SST+ Jobber Drill Bit (#25) is the solution to burnt bits and work-hardened metal. Built with a robust cobalt blend, this bit is specifically tailored to cut through hard metals that typically destroy standard drill bits. When you are fabricating custom parts, frames, or piping systems, you need a tool that bites instantly and cuts cleanly, and that is exactly what the SST+ delivers.

The 135-degree self-centering split point is a game-changer for welders working on curved surfaces, such as pipes or tubing. Standard bits often "walk" across the surface, scratching the finish and ruining the precision of the hole location. The Walter SST+ bites immediately upon contact, ensuring your hole is exactly where you marked it. This feature is invaluable when working with hand drills in awkward positions where applying massive feed pressure is difficult. The bit does the work for you, cutting freely and aggressively.

Furthermore, the heavy-duty web construction of the 01B525 provides the structural integrity needed to resist snapping under the torque and stress of handheld drilling operations. The #25 size (0.1495") is frequently used for rivet holes or specific tap preparations, making it a staple in any fabricator's toolbox. The bronze surface treatment not only identifies the premium quality of the bit but also helps shed heat, keeping the cutting edge cooler for longer. When your project deadline is looming and you have dozens of holes to drill in 304 or 316 stainless, trust the Walter SST+ to get the job done without slowing you down.
