01B508 - Walter SST+ Cobalt Drill Bit #8 Wire Gauge

Premium Cobalt Drilling Performance

The Walter 01B508 SST+ Jobber Drill Bit (#8) represents the pinnacle of drilling technology for industrial applications. Engineered from a premium cobalt blend, this tool is specifically designed to tackle the toughest materials found in MRO and fabrication environments, including stainless steel, mild steel, and non-ferrous metals. The inclusion of cobalt in the high-speed steel matrix significantly increases the bit's hot hardness, allowing it to maintain a sharp cutting edge even under the high thermal loads generated when drilling hard alloys.

What sets the SST+ series apart is its unique geometry. The exclusive "Speed Tip" is self-centering, which effectively prevents the bit from "walking" or wandering across the workpiece surface upon initial contact. This feature eliminates the prerequisite of center punching, streamlining the workflow and increasing precision. Furthermore, the drill bit features a "High Flow" flute design and a back-tapered body. These structural elements work in tandem to evacuate chips rapidly and reduce friction along the margins, preventing binding and ensuring a cleaner, more accurate hole.

Durability is further enhanced by Walter's proprietary bronze SST surface treatment. This coating acts as a lubricant, reducing the coefficient of friction between the tool and the workpiece, which in turn lowers heat generation—the primary cause of drill bit failure. Whether utilized in a stationary drill press or a portable hand drill, the Walter 01B508 delivers consistent, high-performance results, making it an essential component of any professional tooling inventory.
