01A005 - Walter SST 5/64 Inch Cobalt Drill Bit with Quick Shank

High-Performance Drilling with Walter SST Technology

The Walter 01A005 5/64" SST Jobber Drill Bit represents a significant leap forward in drilling technology for industrial maintenance and fabrication. Engineered by Walter Surface Technologies, this bit is designed to address the common frustrations associated with standard high-speed steel bits. At its core, the SST drill bit utilizes a premium cobalt blend material. This composition significantly enhances the bit's heat resistance and hardness, allowing it to maintain a sharp cutting edge even when subjected to the high temperatures generated during continuous drilling in mild steel and non-ferrous metals.

One of the standout features of this tool is the exclusive Quick Shank. In professional environments, bit slippage within the chuck is a frequent productivity killer that can also damage the tool holder. The Quick Shank is precision-engineered to lock securely into both keyed and keyless chucks, ensuring zero slippage and maximum power transmission from the drill motor to the workpiece. This feature alone makes it an indispensable asset for MRO professionals who require reliability and speed.

Precision is paramount when working with expensive materials or critical components. The Walter SST bit features a self-centering "Speed Tip" that bites into the material immediately upon contact. This eliminates the phenomenon known as "walking," where the bit skitters across the surface before penetrating, often necessitating a center punch. With the Speed Tip, operators can drill accurate holes on flat or even round surfaces, such as pipes and tubing, with ease. Furthermore, the back-tapered body design reduces surface contact between the bit and the hole wall, minimizing friction and heat buildup, which further extends the life of the tool.

Designed with a heavy-duty, fully ground body, this drill bit is robust enough to handle rigorous daily use. The special bronze SST surface treatment acts as an additional shield against wear and corrosion. Whether you are drilling through multiple layers of thin gauge metal or performing general fabrication tasks, the Walter 01A005 delivers consistent, high-quality results that professionals trust.
