Walter SST+ Cobalt Drill Bit #55 Wire Gauge Jobber Length

Heavy-Duty Cobalt Drill Bit for Fabricators

Fabricators and welders know that drilling through stainless steel and hard alloys can destroy inferior bits in seconds. The Walter #55 SST+ Jobber Drill Bit is built specifically to solve this problem. With a heavy-duty cobalt blend construction, this bit is designed to cut through the hardest metals used in modern welding and fabrication shops without dulling prematurely. The 01B555 provides a precise #55 wire gauge hole (0.0520 inches), making it ideal for precision fit-ups, rivet holes, and tapping preparation.

One of the biggest frustrations in metal fabrication is "bit walking," where the drill skids across the surface before digging in. Walter has eliminated this with their self-centering Speed Tip. This advanced point geometry allows you to start drilling exactly where you need to, even on round stock or polished stainless surfaces, without needing a center punch. This saves time on every hole and ensures your fabrication tolerances are met. The bit also features a robust web construction that resists snapping under the high torque often required when drilling through thick plate or structural steel.

The SST+ isn't just about toughness; it's about speed. The specialized flute design ejects metal chips efficiently, keeping the cutting edge cool and sharp. This allows you to drill more holes in less time, increasing overall shop productivity. The back-tapered body prevents the bit from seizing in the hole, a common issue when drilling deep into thick materials. Whether you are using a hand drill on a job site or a drill press in the shop, the Walter SST+ #55 bit delivers the professional results serious welders demand.
