Walter 17/64" SST Cobalt Jobber Drill Bit with Quick Shank

Industrial Grade Precision for MRO and Fabrication

The Walter 01A017 17/64" SST Jobber Drill Bit sets a new standard for performance in industrial maintenance, repair, and operations (MRO). Designed specifically for the demands of professional fabrication, this bit combines advanced metallurgy with superior geometric engineering. At its core is a high-performance cobalt blend substrate, which maintains hardness at elevated temperatures, making it suitable for continuous drilling in mild steel, aluminum, and non-ferrous metals.

One of the critical features for professional welders and fabricators is the Quick Shank design. In high-torque applications, standard round shanks frequently slip within the chuck, leading to galled shanks and damaged jaws. The Quick Shank profile ensures a positive drive, preventing slippage entirely. This is particularly advantageous when using hand-held cordless drills in field applications where stability and torque transfer are paramount.

The geometry of the SST bit is optimized for thin gauge and sheet metal applications. The 135-degree split point, referred to as the "Speed Tip," allows for aggressive penetration with reduced feed pressure. This self-centering capability is essential when drilling on curved surfaces, such as piping or tubing, without the aid of a drill press. Additionally, the heavy-duty fully ground body features a back taper that prevents binding—a common issue when drilling through multiple stacked layers of metal.

Surface treated with a specialized bronze SST coating, the bit resists chip welding and promotes efficient chip flow. This reduces thermal buildup, protecting the temper of the bit and the integrity of the workpiece. For professionals seeking a reliable, long-lasting solution that enhances the efficiency of their cordless tooling inventory, the Walter SST Jobber Drill Bit is the superior choice.
