01A020A - Walter SST+ 5/16" Cobalt Jobber Drill Bit with Quick Shank

High-Performance Cobalt Drilling Solution

The Walter 01A020A 5/16" SST Jobber Drill Bit represents a pinnacle in drilling technology, specifically engineered for industrial maintenance and fabrication environments. Crafted from a high-grade cobalt blend, this drill bit is designed to withstand high temperatures and abrasive wear, making it a reliable choice for consistent performance in mild steel, aluminum, and non-ferrous metals. The tool features a heavy-duty fully ground body construction that ensures straight, accurate holes every time, reducing the likelihood of bit breakage under stress.

One of the standout features of this SST bit is the exclusive "Speed Tip." This self-centering point geometry allows the operator to start drilling immediately without the need for a center punch, preventing the bit from "walking" across the workpiece. This precision is critical when working on curved surfaces or thin gauge metals where accuracy is paramount. Furthermore, the bit is finished with a special bronze SST surface treatment, which significantly reduces friction during operation. This coating aids in heat dissipation and smooth chip flow, preventing material buildup on the flutes.

Designed with modern tooling in mind, the 01A020A incorporates Walter's innovative Quick Shank technology. This shank design guarantees a rapid and secure tightening mechanism within both keyed and keyless chucks, eliminating the common frustration of bit slippage during high-torque applications. This feature makes the SST drill bit particularly effective for use with cordless drills, as the efficient cutting action and reduced friction help maximize the number of holes that can be drilled per battery charge. Whether for general maintenance, assembly, or fabrication, this Walter drill bit delivers professional-grade results.
