01A019 - Walter SST+ 19/64" Cobalt Jobber Drill Bit with Quick Shank

High-Performance Walter SST Drill Bit for Precision Metalworking

The Walter 01A019 19/64" SST Jobber Drill Bit represents the pinnacle of drilling technology for industrial maintenance and fabrication. Designed with the professional user in mind, this tool addresses the common frustrations associated with standard drill bits, particularly when used with cordless power tools. At the core of its performance is the exclusive Quick Shank technology. This innovative shank design features longitudinal flats that allow the chuck jaws to grip the bit securely, completely eliminating the risk of the bit spinning inside the chuck during high-torque applications. This ensures that every ounce of power from your drill is transferred directly to the cutting edge, maximizing efficiency and protecting your equipment.

Material composition is critical in industrial drilling, and the Walter SST series excels with a proprietary cobalt blend. This high-grade material provides exceptional heat resistance, allowing the bit to maintain its hardness even when drilling through tough mild steel and non-ferrous metals at high speeds. The addition of a bronze SST surface treatment further enhances performance by reducing friction and facilitating smooth chip evacuation. This results in a cooler drilling process and significantly extends the lifespan of the tool, making it a cost-effective choice for high-volume operations.

Precision is guaranteed thanks to the heavy-duty, fully ground body construction. Unlike roll-forged bits, the Walter SST is ground to exact tolerances, ensuring that the hole you drill is the exact size you intended. The geometry of the bit includes a back-tapered body, which slightly reduces the diameter behind the cutting tip. This clever engineering reduces surface contact with the sidewalls of the hole, preventing binding and overheating, especially in deeper drilling tasks. Whether you are working with aluminum, mild steel, or thin gauge sheet metal, the Walter 01A019 delivers consistent, reliable results that meet the rigorous standards of the MRO industry.

Furthermore, the self-centering "Speed Tip" geometry allows for immediate engagement with the workpiece. This feature is particularly beneficial when drilling on curved surfaces or pipes, as it prevents the bit from "walking" or skating across the material. This eliminates the need for pre-punching, saving valuable time and effort on the job site. For professionals seeking a robust, efficient, and precise drilling solution, the Walter SST Jobber Drill Bit is the superior choice.
