01E121 - Walter SST+ Quick Shank Drill Bit Set 1/16-3/8 Inch

Stop Bits from Slipping and Start Drilling Faster

For professional welders and metalworkers, few things are more frustrating than a drill bit that spins in the chuck right when you are trying to push through a piece of heavy plate. The Walter 01E121 SST+ Drill Bit Kit solves this problem once and for all with its innovative Quick Shank technology. The bits in this set feature three flat sides on the shank, ensuring your drill chuck grabs hold tight and never lets go. Whether you are drilling out broken bolts, prepping holes for fasteners, or fabricating custom brackets, these bits deliver the torque you need without the hassle of constant re-tightening.

This kit covers the essential size range from 1/16" to 3/8", making it the perfect "go-to" set for your welding cart or field box. The bits are made from a special cobalt-infused High Speed Steel that is specifically designed to handle the heat generated when drilling stainless steel and hard alloys. This means you get more holes per bit and spend less time running to the tool crib for replacements. The 135-degree split point tip bites into the metal instantly—no walking, no skating, and no need to waste time with a center punch on every single hole.

Durability is key in a welding environment, and Walter delivers. The robust web design of these bits resists snapping, even when you are applying heavy feed pressure or working in awkward positions where the drill might not be perfectly perpendicular. The included storage case is built tough to survive drops and banging around in a truck bed, keeping your bits sorted and ready for action. Invest in the Walter 01E121 kit and experience the difference that professional-grade cutting tools make in your daily fabrication workflow.
