01A024 - Walter SST+ 3/8-Inch Jobber Drill Bit with Quick Shank Technology

High-Performance Drilling with Walter SST Technology

The Walter 01A024 3/8" SST Jobber Drill Bit represents a significant leap forward in drilling technology, specifically engineered to address the common frustrations faced by maintenance and fabrication professionals. At the heart of this tool is Walter's exclusive Quick Shank design. Unlike traditional round shanks that often slip inside the chuck under high torque—damaging both the bit and the tool—the Quick Shank features longitudinal flats that ensure a positive, slip-free drive. This secure connection allows for maximum power transmission, making it an indispensable asset for heavy-duty applications where reliability is paramount.

Constructed from a premium cobalt blend, this drill bit is designed to withstand the high temperatures generated when drilling through tough materials like mild steel and non-ferrous metals. The addition of cobalt significantly enhances the bit's red hardness, allowing it to maintain a sharp cutting edge longer than standard high-speed steel bits. This durability is further complemented by a special bronze SST surface treatment, which reduces friction and facilitates smooth chip evacuation, preventing heat buildup that can lead to premature failure.

Efficiency is a key focus of the Walter SST line. The bit features a self-centering "Speed Tip" that bites into the material immediately upon contact, eliminating the need for pre-punching or pilot holes. This geometry not only speeds up the drilling process but also prevents the bit from wandering, ensuring precise hole placement even on curved surfaces like pipes or tubing. Furthermore, the body of the bit is back-tapered, a design choice that reduces contact with the sidewalls of the hole, thereby minimizing friction and binding. For professionals using cordless power tools, these friction-reducing features translate directly to extended battery life, allowing for more holes drilled per charge.

Whether you are working with thin gauge sheet metal, aluminum, or general structural steel, the Walter 01A024 delivers consistent, high-quality results. Its robust construction and intelligent design features make it a top-tier choice for industrial environments where speed, accuracy, and tool longevity are critical.
