01B556 - Walter SST+ Cobalt Blend Jobber Drill Bit, Wire Gauge #56

Precision Engineering for Tough Materials

The Walter 01B556 SST+ Jobber Drill Bit represents the pinnacle of drilling technology for industrial applications. Designed to tackle the most demanding materials, this #56 wire gauge bit is crafted from a proprietary cobalt blend that provides exceptional red hardness. This material composition allows the bit to maintain its cutting edge even under the high temperatures generated when drilling through tough alloys like stainless steel. Unlike standard high-speed steel bits that dull quickly, the SST+ series is engineered to withstand thermal stress, ensuring a significantly longer service life and reduced downtime for tool changes.

At the core of the SST+ performance is the exclusive "Speed Tip" design. This self-centering geometry eliminates the common issue of bit wandering or "walking" upon initial contact with the workpiece. Operators can achieve precise hole placement without the need for pre-drilling or center punching, streamlining the fabrication process. The tip engages the material instantly, reducing the axial force required and minimizing operator fatigue during repetitive drilling tasks. This feature is particularly beneficial when working on curved surfaces or in awkward positions where stability is difficult to maintain.

Chip evacuation is critical for maintaining drilling efficiency, and the Walter 01B556 excels in this area with its unique "high flow" flute design. The geometry of the flutes is optimized to pull chips away from the cutting zone rapidly, preventing clogging and heat buildup. Coupled with the special bronze SST surface treatment, which acts as a lubricant to reduce friction, the bit cuts cooler and cleaner. Additionally, the back tapered body design provides extra clearance between the bit and the hole wall, virtually eliminating the risk of binding or seizing. Whether used in a portable hand drill or a stationary drill press, this bit delivers consistent, high-quality results across mild steel, non-ferrous metals, and stainless steel.
