01B554 - Walter SST+ Cobalt Jobber Drill Bit - Size #54

Precision Drilling with Walter SST+ Technology

The Walter #54 SST+ Jobber Drill Bit (SKU: 01B554) represents the pinnacle of drilling performance for industrial maintenance and fabrication. Engineered by Walter Surface Technologies, the SST+ series is specifically designed to overcome the common challenges associated with drilling hard ferrous and non-ferrous metals. At the core of this tool is a premium cobalt blend substrate. Unlike standard high-speed steel (HSS) bits that soften under high temperatures, the cobalt composition allows the SST+ to maintain its hardness and cutting edge even when subjected to the extreme heat generated by drilling stainless steel and other tough alloys.

Precision is paramount with the #54 wire gauge size (0.0550 inches). To ensure accuracy from the very first rotation, Walter has integrated their exclusive Speed Tip design. This self-centering geometry eliminates the phenomenon known as "walking," where the bit skids across the workpiece before penetrating. This feature allows operators to drill precise holes without the prerequisite step of using a center punch, significantly streamlining workflow in high-volume environments. Furthermore, the bit features a sophisticated High Flow flute design. This geometry is optimized to evacuate chips rapidly from the hole, preventing heat accumulation and reducing the risk of the bit binding or snapping inside the workpiece.

Durability is further enhanced by the unique bronze SST surface treatment. This specialized coating acts as a lubricant, reducing the coefficient of friction between the bit and the material. Combined with a back-tapered body that reduces contact along the margins, the Walter SST+ minimizes torque requirements and extends battery life on portable tools. Whether utilized in a stationary drill press or a hand-held drill, this bit delivers consistent, round, and burr-free holes in mild steel, stainless steel, and aluminum.
