01A022 - Walter SST+ 11/32-Inch Cobalt Drill Bit with Quick Shank

High-Performance Drilling with Walter SST Technology

The Walter 01A022 11/32" SST Jobber Drill Bit represents the pinnacle of drilling efficiency for industrial applications. Engineered by Walter Surface Technologies, this bit is designed to solve the common frustrations associated with drilling into metal, particularly when using cordless power tools. At the core of its performance is the premium cobalt blend construction. Unlike standard high-speed steel bits, the cobalt infusion provides superior heat resistance, allowing the bit to maintain its cutting edge hardness even at high temperatures. This makes it an exceptional choice for repetitive drilling tasks where thermal buildup typically degrades lesser tools.

One of the standout features of this model is the exclusive Quick Shank. In high-torque applications, round shanks often slip inside the chuck, damaging both the bit and the drill jaws while halting progress. The Quick Shank design features longitudinal flats that lock securely into both keyed and keyless chucks, ensuring 100% power transmission from the motor to the workpiece. This secure grip is particularly beneficial for maintenance and repair operations where reliability is paramount.

Precision is guaranteed through the exclusive self-centering "Speed Tip." This advanced point geometry eliminates the need for center punching, as the bit bites into the material immediately upon contact without "walking" across the surface. This is critical when drilling into round surfaces like pipes or tubing. Furthermore, the back-tapered body and heavy-duty fully ground construction reduce friction along the flutes, preventing binding and ensuring smooth chip evacuation. Finished with a special bronze SST surface treatment, this drill bit glides through mild steel, aluminum, and thin gauge metals with ease, making it a staple for any professional tool crib.
