01A032 - Walter 1/2 Inch SST Cobalt Jobber Drill Bit with Quick Shank

High-Performance Drilling with Walter SST Technology

The Walter 01A032 1/2" SST Jobber Drill Bit represents the pinnacle of drilling efficiency for industrial maintenance and fabrication. Meticulously crafted from a high-grade cobalt blend, this bit is designed to withstand the high temperatures associated with drilling tough metals, ensuring a longer service life compared to standard high-speed steel bits. The core of its performance lies in the heavy-duty fully ground body construction, which provides the rigidity necessary for precise, round holes every time. The special bronze SST surface treatment not only adds a layer of protection but also significantly aids in chip evacuation, reducing friction and heat buildup that can dull cutting edges prematurely.

One of the standout features of this drill bit is the innovative Quick Shank. In high-torque applications, standard round shanks often slip inside the chuck, damaging both the bit and the tool. The Quick Shank design features three flat surfaces that lock securely into both keyed and keyless chucks, guaranteeing 100% power transmission. This secure fastening is crucial for safety and efficiency in professional environments. Furthermore, the bit features a back-tapered body, which minimizes contact with the sidewalls of the hole, further reducing friction and allowing for smoother drilling action, particularly in deep hole applications.

Designed with the modern technician in mind, the Walter SST bit is optimized for use with cordless power tools. Its aggressive yet efficient cutting geometry requires less axial force, which translates to less energy consumption. This means operators can drill significantly more holes on a single battery charge, boosting productivity on job sites where power sources are limited. Whether you are working with mild steel, aluminum, or non-ferrous metals, this bit delivers consistent, high-quality results.

Technical Specifications and Applications

The 01A032 is a jobber-length bit, making it the standard choice for a wide range of general-purpose drilling tasks. Its self-centering "Speed Tip" is a critical time-saver, allowing the operator to start drilling immediately without the need for a center punch, even on curved surfaces like pipes or tubing. This feature, combined with its ability to drill through multiple layers of thin-gauge metal without grabbing or distorting the material, makes it an indispensable tool for HVAC, automotive, and general fabrication sectors.
