01A017A - Walter 17/64 Inch SST Cobalt Jobber Drill Bit with Quick Shank

High-Performance Industrial Drilling Precision

The Walter 01A017A 17/64" SST Jobber Drill Bit represents the pinnacle of drilling technology for industrial maintenance and fabrication. Engineered with a proprietary cobalt blend, this tool is designed to withstand the high temperatures generated during continuous drilling operations, significantly extending the life of the bit compared to standard high-speed steel alternatives. The heavy-duty, fully ground body construction ensures structural integrity, making it a reliable choice for demanding environments where precision and durability are non-negotiable.

One of the standout features of the SST series is the exclusive "Speed Tip." This self-centering point geometry eliminates the need for pre-punching, allowing operators to start holes precisely where intended, even on curved or round surfaces. This feature not only saves time but also reduces the likelihood of workpiece damage caused by bit walking. Furthermore, the back-tapered body design minimizes friction between the bit and the hole wall, preventing binding and ensuring smooth chip evacuation. This is particularly beneficial when drilling through multiple layers of metal or working with thin gauge sheet metal.

Efficiency is further enhanced by the innovative Quick Shank design. This shank geometry guarantees a positive drive in both keyed and keyless chucks, eliminating the frustration of bit slippage under high torque. For professionals utilizing cordless power tools, the Walter SST bit is optimized to reduce energy consumption, allowing for more holes drilled per battery charge. The special bronze SST surface treatment adds a final layer of protection, reducing wear and facilitating smoother cutting action across a variety of materials including mild steel and aluminum.
