01A024A - Walter 3/8-Inch SST Cobalt Drill Bit with Quick Shank

Premium Performance for Industrial Drilling

The Walter 01A024A 3/8" SST Jobber Drill Bit represents the pinnacle of drilling technology for maintenance, repair, and fabrication professionals. Built on the legacy of the proven original SST design, this bit is crafted from a specialized cobalt blend that provides exceptional hardness and heat resistance. This material composition allows the bit to maintain its cutting edge even under the high thermal loads generated when drilling through tough metals, significantly extending the service life of the tool compared to standard high-speed steel bits.

One of the standout features of this drill bit is the exclusive Quick Shank technology. In high-torque applications, standard round shanks often spin within the chuck, damaging both the bit and the drill. The Quick Shank design features engineered flats that lock securely into both keyed and keyless chucks, ensuring positive drive transmission and preventing slippage entirely. This secure connection translates to more efficient energy transfer, which is particularly beneficial when using cordless power tools, as it maximizes the number of holes drilled per battery charge.

Precision is at the core of the SST design. The bit features a self-centering "Speed Tip" that bites into the material immediately upon contact, eliminating the need for pre-punching or pilot holes. This feature prevents the bit from "walking" across the workpiece, ensuring accurate hole placement every time. The heavy-duty fully ground body and back tapered geometry reduce friction along the flutes, allowing for smoother drilling and cleaner hole exits. Whether you are working with mild steel, aluminum, or thin gauge sheet metal, the Walter SST drill bit delivers reliable, high-speed performance that industrial environments demand.
