01B543 - Walter SST+ Cobalt Jobber Drill Bit #43 Wire Gauge

High-Performance Industrial Drilling Solution

The Walter 01B543 SST+ Jobber Drill Bit (Size #43) represents the pinnacle of drilling technology for industrial maintenance, repair, and operations (MRO). Engineered by Walter Surface Technologies, this bit is designed to tackle the most demanding materials found in modern manufacturing and fabrication environments. At the core of its performance is a proprietary high-grade cobalt blend. Unlike standard High-Speed Steel (HSS) bits, the cobalt matrix provides exceptional red hardness, allowing the bit to maintain its cutting edge even under the extreme temperatures generated when drilling tough alloys like stainless steel.

Efficiency in production environments is driven by cycle time and tool longevity. The SST+ series addresses both with its innovative "High Flow" flute design. This geometry is meticulously engineered to evacuate chips rapidly from the hole. Efficient chip removal is critical when drilling work-hardening materials; if chips are not cleared immediately, they can cause heat buildup that hardens the material and dulls the tool. The Walter 01B543 mitigates this risk, ensuring consistent, clean holes and significantly extending the lifespan of the drill bit.

Precision is paramount in machine shops and assembly lines. This drill bit features Walter's exclusive "Speed Tip," a self-centering point geometry that bites into the material immediately upon contact. This eliminates the phenomenon known as "walking," where a bit skids across the surface before penetrating. For operators, this means there is often no need to pre-punch the material, saving a valuable step in the fabrication process. Furthermore, the back-tapered body design reduces friction along the sides of the bit, minimizing drag and allowing for higher feed rates without compromising the integrity of the tool or the workpiece.

The 01B543 is finished with a specialized bronze SST surface treatment. This coating not only identifies the premium nature of the tool but also acts as a lubricant layer that further reduces heat generation. Whether utilized in stationary drill presses or portable hand drills, the Walter SST+ #43 drill bit delivers reliable, heavy-duty performance across mild steel, non-ferrous metals, and particularly stainless steel applications.
