01A021 - Walter 21/64 Inch SST Cobalt Jobber Drill Bit with Quick Shank

High-Performance Drilling with Walter SST Technology

The Walter 01A021 21/64" SST Jobber Drill Bit is engineered to redefine your drilling experience, particularly when working with mild steel, aluminum, and thin gauge metals. At the heart of this tool is a robust cobalt blend construction, which provides exceptional resistance to heat and wear. This makes it a reliable choice for maintenance, repair, and operations (MRO) professionals who demand longevity from their consumables. Unlike standard high-speed steel bits that may dull quickly under thermal stress, the SST series maintains its cutting edge longer, ensuring you get the most out of every bit.

One of the standout features of this drill bit is the exclusive Quick Shank design. Slippage in the chuck is a common frustration that not only wastes time but can also damage the bit shank and the drill chuck itself. Walter’s Quick Shank solves this by incorporating specific flats that allow for a secure, positive lock in both keyed and keyless chucks. This ensures maximum torque transmission from your power tool to the workpiece, making your drilling operations smoother and more efficient. Whether you are using a stationary drill press or a portable hand drill, the stability provided by this shank design is immediately noticeable.

Efficiency is further enhanced by the self-centering "Speed Tip." This advanced point geometry allows the bit to bite into the material immediately upon contact, eliminating the need for pre-drilling or center punching. This is particularly advantageous when drilling on round surfaces like pipes or tubing, where standard bits often "walk" off the mark. Additionally, the back-tapered body design reduces friction along the sides of the hole, preventing binding and heat buildup. For professionals using cordless tools, this friction reduction translates directly to extended battery life, allowing you to drill more holes per charge. The Walter 01A021 is a versatile, high-quality solution for precise and rapid hole creation.
