01A015A - Walter 15/64-Inch SST Cobalt Drill Bit with Quick Shank

Premium Performance with Walter SST Drill Bits

The Walter 15/64" SST Jobber Drill Bit (SKU: 01A015A) represents the pinnacle of drilling technology for maintenance, repair, and fabrication professionals. Engineered from a proprietary premium cobalt blend, this bit is designed to withstand the high temperatures generated during aggressive drilling applications, ensuring a longer service life compared to standard high-speed steel bits. The core of its performance lies in its heavy-duty, fully ground body construction, which provides exceptional structural integrity and precision.

One of the standout features of this drill bit is the exclusive Quick Shank. Traditional round shanks often suffer from slippage within the chuck, especially under heavy loads or when biting into tough materials. The Quick Shank design incorporates specific flats that lock securely into both keyed and keyless chucks, transmitting maximum torque without slipping. This feature is particularly beneficial for users of cordless power tools, as it ensures that every rotation of the motor is effectively transferred to the cutting edge, thereby maximizing battery efficiency and allowing for more holes to be drilled on a single charge.

Precision is paramount in metalworking, and the Walter SST bit addresses this with its self-centering "Speed Tip." This innovative point geometry prevents the bit from "walking" or wandering across the workpiece surface when starting a hole, eliminating the need for a center punch in many scenarios. Furthermore, the bit features a back-tapered body which reduces friction along the flutes, allowing for smoother drilling and easier withdrawal from deep holes. Finished with a special bronze SST surface treatment, this tool is not just a drill bit; it is a productivity enhancer for working with mild steel, aluminum, and thin gauge metals.
