01A031 - Walter SST+ 31/64" Cobalt Jobber Drill Bit with Quick Shank

High-Performance Cobalt Drilling Solution

The Walter 01A031 31/64" SST Jobber Drill Bit represents a significant advancement in drilling technology for industrial maintenance and fabrication. Engineered with a premium cobalt blend, this bit is designed to withstand high temperatures and abrasive materials, ensuring a longer service life compared to standard high-speed steel bits. The core of its performance lies in the robust fully-ground construction which guarantees concentricity and precision in every hole drilled.

One of the standout features of this model is the exclusive Quick Shank technology. Slippage within the drill chuck is a common issue that damages both the bit shank and the chuck jaws, leading to downtime and frustration. The Quick Shank design features flats that lock securely into both keyed and keyless chucks, transmitting torque more effectively and preventing the bit from spinning under load. This is particularly advantageous when working with tough materials where higher torque is required.

Efficiency is further enhanced by the self-centering Speed Tip. This specialized point geometry allows the bit to bite into the material immediately upon contact, eliminating the phenomenon of "walking" across the surface. This feature removes the necessity for pre-punching center marks, streamlining the workflow. Additionally, the bit features a bronze SST surface treatment which acts as a lubricant to reduce friction and heat buildup, and a back-tapered body to prevent binding. Optimized for cordless tools, it allows users to drill more holes per battery charge, making it an essential tool for mobile maintenance crews.
