01A029A - Walter SST+ 29/64" Cobalt Drill Bit with Quick Shank

Reliable Metal Fabrication with Walter Cobalt Drill Bits

For professional welders and fabricators, the quality of a hole often dictates the quality of the fit-up. The Walter 01A029A 29/64" SST+ Drill Bit is built to meet the rigorous demands of the welding shop and the job site. Constructed from a premium cobalt blend, this heavy-duty tool is engineered to penetrate hard metals that would dull lesser bits instantly. When prepping materials for welding or bolting, the ability to drill clean, precise holes in stainless steel and heavy-gauge aluminum without overheating the workpiece is a critical advantage.

The reality of modern fabrication involves a heavy reliance on cordless tools. Walter has optimized the SST+ series specifically for this purpose. The innovative Quick Shank feature prevents the bit from spinning inside the chuck, a common frustration that damages both the bit shank and the drill chuck jaws. By ensuring a positive drive, the Quick Shank allows the high-torque motors of modern cordless drills to operate at peak efficiency. This efficiency, combined with the aggressive cutting action of the bit, significantly extends battery life, allowing you to complete more work on a single charge.

Drilling on round stock, such as handrails, piping, or tubing, presents unique challenges. Standard bits tend to wander, scarring the material and creating inaccurate holes. The Walter SST+ features a self-centering Speed Tip that penetrates round surfaces effortlessly without the need for a center punch. This feature alone saves valuable time during layout and assembly. Furthermore, the drill's body is fully ground and back-tapered, a design choice that prevents the bit from binding in deep holes or when drilling through multiple layers of stacked sheet metal.

Durability is further enhanced by the bronze SST surface treatment, which helps shed heat and chips rapidly. This thermal management is crucial when drilling work-hardening materials like stainless steel. With the Walter 01A029A, welders get a tool that stays sharp longer, cuts faster, and provides the safety and control needed for precision fabrication. Whether you are installing brackets, creating pilot holes, or fabricating custom parts, this drill bit delivers the industrial-grade performance required to get the job done right the first time.
