01K016 - Walter 1/4 Inch SST+ Double-Ended Cobalt Stub Drill Bit

The Tough Little Bit That Does the Work of Two

If you are tired of snapping long drill bits when working on sheet metal or drilling out spot welds, the Walter 01K016 1/4" SST Double-End Stub Drill is the solution your toolbox needs. This isn't your average hardware store drill bit; it is built for the shop floor where tools take a beating. The first thing you'll notice is the "stub" design. Because it's shorter than a standard bit, it is incredibly rigid. You can lean into it with a hand drill without worrying about it flexing and snapping off in the hole. It gives you the control you need for tight spaces and tough materials.

The real money-saver here is the double-ended design. When one side finally gets dull after drilling hundreds of holes, you don't throw it away—you just flip it around and keep working. It's literally two bits in one. The metal itself is a special Cobalt blend that holds an edge way longer than standard black oxide bits, especially when you are drilling into stainless steel or hard alloys. It handles the heat better, meaning you spend less time sharpening or replacing bits and more time fabricating.

Walter also added their SST surface treatment, which helps the bit slide through metal with less friction. Combined with the 135-degree split point, this bit bites into the metal immediately. You don't need to waste time with a center punch; just line it up and pull the trigger. The bit stays where you put it. Whether you are drilling rivets, installing panels, or just need a reliable 1/4-inch hole in a hurry, this double-ended stub drill is designed to keep up with the pace of a busy welding shop.
