01A018A - Walter SST+ 9/32 Inch Cobalt Jobber Drill Bit with Quick Shank

High-Performance Drilling with Walter SST Technology

The Walter 01A018A 9/32" SST Jobber Drill Bit represents the pinnacle of drilling efficiency for industrial maintenance and fabrication. Engineered by Walter Surface Technologies, this bit is crafted from a specialized cobalt blend that provides exceptional heat resistance and structural integrity, allowing it to maintain a sharp cutting edge even under rigorous use. The defining feature of this tool is its exclusive Quick Shank technology. Unlike traditional round shanks that can spin inside the chuck under high torque, the Quick Shank features longitudinal flats that lock securely into both keyed and keyless chucks. This positive drive mechanism ensures maximum power transmission from the tool to the workpiece, eliminating frustration and damage to the bit shank.

Precision is paramount in MRO environments, and the SST bit delivers with its advanced geometry. The bit features a self-centering "Speed Tip" that bites into the material immediately upon contact. This eliminates the common issue of "walking" or wandering across the surface, removing the need for pre-punching center holes and saving valuable time during assembly or repair tasks. The body of the bit is back-tapered, a design choice that significantly reduces friction along the flutes. By minimizing surface contact between the bit and the hole walls, heat generation is kept to a minimum, which preserves the temper of the bit and prevents work-hardening of the metal.

Designed for versatility, the Walter SST Jobber bit excels in drilling a wide range of materials, including mild steel, aluminum, and non-ferrous metals. Its bronze SST surface treatment further aids in chip evacuation and lubricity, ensuring smooth operation. Whether used in a stationary drill press or a portable hand drill, this bit offers consistent, reliable performance. It is particularly effective for drilling round surfaces, such as pipes or tubing, where the self-centering tip proves indispensable for accurate hole placement.
