01A011 - Walter 11/64" SST+ Jobber Drill Bit with Quick Shank

Precision Engineering for Industrial Drilling

The Walter 01A011 11/64" SST Jobber Drill Bit represents a significant advancement in drilling technology, specifically engineered to address the common challenges faced by industrial professionals. At the core of this tool is Walter's proprietary cobalt blend construction. Unlike standard high-speed steel bits, this cobalt-infused material offers superior heat resistance, allowing the bit to maintain its cutting edge even under the thermal stress of continuous drilling. This makes it an exceptional choice for maintenance, repair, and operations (MRO) environments where tool longevity and reliability are paramount.

One of the standout features of the SST series is the exclusive Quick Shank design. In high-torque applications, standard round shanks often slip within the chuck, damaging both the bit and the drill jaws. The Quick Shank features engineered flats that lock securely into both keyed and keyless chucks, ensuring positive torque transmission. This design is particularly beneficial for users of cordless power tools, as it ensures that every ounce of motor power is transferred directly to the cutting edge, maximizing efficiency.

Precision is further enhanced by the self-centering "Speed Tip." This advanced point geometry eliminates the phenomenon of "walking"—where the bit skitters across the workpiece before penetrating. This allows for precise hole placement without the prerequisite of center punching, saving valuable time during assembly and fabrication tasks. Additionally, the bit features a back-tapered body which slightly reduces the diameter behind the cutting flutes. This subtle engineering choice significantly reduces friction against the sidewalls of the hole, preventing binding and breakage when drilling through deep or multi-layered materials. Finished with a special bronze SST surface treatment, this bit clears chips effectively and runs cooler, delivering a superior drilling experience in aluminum, mild steel, and thin gauge metals.
