01A008 - Walter SST 1/8 Inch Cobalt Blend Jobber Drill Bit with Quick Shank

Precision Drilling with Walter SST Technology

The Walter 01A008 1/8" SST Jobber Drill Bit represents a significant leap forward in drilling efficiency and precision for industrial professionals. Designed by Walter Surface Technologies, this bit is engineered to address the common frustrations associated with drilling metal, particularly when using cordless power tools. At the heart of its performance is the exclusive Quick Shank design. Unlike traditional round shanks that can slip and spin within the chuck under high torque, the Quick Shank features a specialized geometry that locks securely into both keyed and keyless chucks. This ensures that every ounce of power from your drill is transferred directly to the cutting edge, preventing damage to the bit shank and the drill chuck alike.

Material composition is critical for any cutting tool, and the Walter SST series utilizes a premium cobalt blend. This high-performance material provides exceptional heat resistance and hardness, allowing the bit to maintain a sharp cutting edge even when drilling through tough mild steel and non-ferrous metals. The addition of a special bronze SST surface treatment further enhances performance by reducing friction and facilitating smooth chip evacuation. This combination of material and coating results in a drill bit that runs cooler and lasts significantly longer than standard high-speed steel bits, making it a cost-effective choice for high-volume fabrication environments.

Accuracy is paramount in professional applications, and the 01A008 delivers with its self-centering Speed Tip. This innovative tip geometry bites into the material immediately upon contact, eliminating the "walking" or wandering often experienced with standard bits. This feature removes the need for pre-punching, saving valuable time on the job site. Furthermore, the back tapered body design reduces surface contact between the bit and the hole walls, minimizing binding and heat buildup. Whether you are drilling through thin gauge sheet metal, aluminum, or round surfaces, the Walter SST Jobber Drill Bit provides the reliability and speed required for top-tier industrial maintenance and fabrication.
