01A009 - Walter 9/64 Inch SST Cobalt Drill Bit with Quick Shank

High-Performance Drilling with Walter SST Technology

The Walter 01A009 9/64" SST Jobber Drill Bit represents a significant advancement in drilling technology, specifically engineered for maintenance, repair, and operations (MRO) professionals who demand reliability and precision. At the core of this tool is a proprietary cobalt blend, which provides exceptional heat resistance and hardness. This material composition allows the bit to maintain its cutting edge significantly longer than standard high-speed steel (HSS) bits, even when subjected to the high temperatures generated during continuous drilling applications. The bronze SST surface treatment further enhances performance by reducing friction and facilitating smooth chip evacuation, preventing heat buildup that can lead to premature tool failure.

One of the standout features of this drill bit is the exclusive Quick Shank design. In high-torque applications, standard round shanks often slip within the chuck, damaging both the bit and the drill's jaws. The Quick Shank features longitudinal flats that lock securely into both keyed and keyless chucks, ensuring positive drive transmission. This design is particularly beneficial for users of cordless power tools, as the efficient transfer of torque translates to less energy waste and more holes drilled per battery charge. The shank design effectively bridges the gap between standard round shank bits and hex shank bits, offering the security of the latter with the precision of the former.

Precision is further guaranteed by the exclusive "Speed Tip" geometry. This self-centering point eliminates the need for pre-punching, allowing the operator to place the bit exactly where the hole is required without it "walking" across the workpiece. This is critical when working on curved surfaces or expensive materials where surface damage must be avoided. Additionally, the body of the bit is back-tapered, a subtle engineering detail that prevents the bit from binding in the hole, reducing the risk of breakage and ensuring a clean, burr-free exit. Whether for drilling mild steel, aluminum, or thin gauge sheet metal, the Walter 01A009 delivers consistent, professional results.
