Walter SST+ #24 Cobalt Jobber Drill Bit for Stainless Steel

Heavy-Duty Drilling for Fabrication and Welding

For professional welders and fabricators, a drill bit is more than just an accessory—it is a critical tool for preparation and assembly. The Walter #24 SST+ Jobber Drill Bit (01B524) is built to withstand the harsh environment of the welding shop, where cutting through hardened steel and stainless plate is a daily requirement. Standard drill bits often burn out or dull instantly when facing the work-hardening properties of stainless steel, but the SST+ series is formulated with a robust cobalt blend that resists heat and maintains a sharp cutting edge far longer than conventional bits.

Time is money in fabrication, and the Walter SST+ is designed for speed. The aggressive 135° self-centering split point bites into the metal immediately upon contact. This feature is particularly beneficial when working with handheld drills in awkward positions, as it prevents the bit from skating across the workpiece and damaging the finish. You can drill spot welds, rivet holes, or pilot holes with confidence and precision, without needing to reach for a center punch and hammer every time.

The structural integrity of the bit is supported by a heavy-duty web and a special bronze surface treatment that reduces friction. This allows for higher feed rates and faster penetration with less operator fatigue. The #24 size (0.1520 inches) is a specific wire gauge size often used for precision clearance holes or tapping preparation in specialized applications. Whether you are drilling out broken bolts, preparing a chassis for mounting, or fabricating custom brackets, the Walter 01B524 delivers the reliability you need to keep your project moving forward. Stop wasting money on cheap bits that snap and burn; upgrade to the industrial standard of Walter SST+.

Key Benefits for Fabricators

• Bites Instantly: No walking or skating on smooth metal surfaces.
• Drills Stainless: Specifically designed to cut tough alloys without work hardening.
• Resists Breakage: Back-tapered body prevents binding in the hole.
• Longer Life: Cobalt blend handles high heat from aggressive drilling.
