01K015 - Walter 15/64" SST+ Cobalt Double-Ended Stub Drill Bit

The Fabricator's Choice for Sheet Metal

For welders and fabricators working with sheet metal, body panels, or thin-walled tubing, the Walter 15/64" SST Double-End Stub Drill is a game-changer. Standard drill bits often flex and walk when starting a hole on smooth metal surfaces, leading to scratched finishes and inaccurate holes. This Walter bit solves that problem with its stubby, rigid design and unique self-centering point. It grabs the metal instantly, allowing you to drill precise holes exactly where you need them without the hassle of using a center punch.

Durability is essential in a welding shop, and this bit delivers. Crafted from a special Cobalt HSS alloy, it is built to withstand the high heat generated when drilling through hardened steel, stainless steel, and aluminum. Unlike cheaper bits that dull after a few holes, the Walter SST maintains its cutting edge longer, ensuring you spend more time fabricating and less time swapping out dull tools. The double-ended design is particularly convenient; when one side finally wears down, simply flip the bit around in your chuck and keep working. It's like having a backup bit ready to go at all times.

Clean holes are critical for strong welds and proper rivet seating. The SST+ geometry and high-flow flutes of this bit are designed to eject chips quickly and cut cleanly, leaving minimal burrs on the exit side of the hole. This reduces the amount of post-drilling cleanup and deburring required, speeding up your overall production time. Whether you are drilling out spot welds, installing rivets, or prepping materials for assembly, this drill bit provides the control and longevity professional welders demand.

Perfect for Tight Spaces

The short "stub" length of this drill bit isn't just about strength; it's also about access. In automotive repair and complex fabrication assemblies, you often need to drill in confined spaces where a long bit just won't fit. The compact profile of the Walter 15/64" stub drill allows you to maneuver into tight corners with your hand drill, making it an indispensable addition to any welder's toolbox.
