01B555 - Walter SST+ Cobalt Drill Bit #55 Wire Gauge Jobber Length

High-Performance Drilling for Industrial MRO

The Walter #55 SST+ Jobber Drill Bit (01B555) represents the pinnacle of drilling technology for maintenance, repair, and operations professionals. Engineered to tackle the toughest materials found in industrial environments, this drill bit features a proprietary cobalt blend that withstands high temperatures and stress better than standard high-speed steel. Whether you are drilling through mild steel, non-ferrous metals, or hardened stainless steel, the SST+ series delivers consistent, reliable performance that reduces downtime and tool changes.

Efficiency is at the core of the SST+ design. The bit utilizes a unique "High Flow" flute geometry which rapidly evacuates chips from the hole, preventing heat buildup and clogging. This is complemented by a back-tapered body design that reduces friction along the sidewalls, minimizing the risk of binding even in deep drilling applications. For MRO technicians, this means smoother operation and less strain on portable power tools. The exclusive bronze SST surface treatment further enhances lubricity, extending the life of the bit significantly under heavy workloads.

Precision is guaranteed with Walter's innovative self-centering "Speed Tip." This 135-degree split point geometry bites into the material immediately upon contact, eliminating the need for center punching or pilot holes. This feature is particularly valuable when working on curved surfaces or in awkward positions where tool walking can damage the workpiece. With the Walter 01B555, you get a #55 wire gauge bit that combines speed, accuracy, and longevity, making it an essential component of any professional tool crib.
