Walter SST+ 13/64 Inch Cobalt Extension Drill Bit 6 Inch Length

Reach Further and Drill Harder

Every welder knows the frustration of trying to drill a hole in a tight spot only to find their standard bit is just an inch too short. The Walter 13/64" SST+ 6" Extension Drill Bit (SKU: 01F513) is your solution for those hard-to-reach places. Designed with a 6-inch overall length, this bit gives you the extra extension you need to drill through thick plates, navigate around obstructions, or create deep pilot holes without compromising on strength or cutting speed. It is the perfect addition to any fabricator's toolbox, ensuring you are never stuck unable to complete a job because of limited access.

But reach isn't the only thing this bit offers; it is built to cut through the toughest metals you encounter in the shop. If you work with stainless steel, you know how quickly it can chew up cheap drill bits. The Walter SST+ series is crafted with a special cobalt blend that resists the intense heat generated when drilling hard alloys. This means the cutting edge stays sharp longer, allowing you to drill more holes per bit and spend less time swapping out dull tools. The 135-degree split point is a game-changer for pipe welders and fitters—it centers itself instantly, so you don't have to waste time with a center punch or worry about the bit skittering across a round pipe.

Durability is key in a welding environment, and the 01F513 delivers. The heavy-duty fully ground body resists snapping, even under the stress of deep drilling. The unique Bronze SST surface treatment helps the bit slide through metal with less friction, keeping temperatures down and preventing the bit from binding up in deep holes. Whether you are drilling out broken bolts, prepping materials for assembly, or fabricating custom brackets, this Walter extension bit provides the reliability and performance professional welders trust. Stop struggling with short, dull bits and upgrade to the heavy-duty performance of Walter SST+.
