For professional welders and fabricators, time is money, and a broken drill bit is a frustration you can't afford. The Walter 01H130 15/32" SST Stub Drill is built to handle the abuse of daily metalworking. If you frequently drill out spot welds, install rivets, or run holes through stainless steel sheet metal, this is the bit you want in your arsenal. The first thing you'll notice is the hex shank. We've all been there—you're pushing hard into a piece of steel, and suddenly the drill chuck spins while the bit stays stationary. That doesn't happen with this bit. The hex shank locks in tight, letting you apply the pressure needed to cut through tough alloys without slipping.
The "stub" length is another game-changer for fabrication work. Because it is shorter than a standard drill bit, it is far more rigid. It doesn't bend or flex when you lean into it, which means it snaps far less often. This rigidity, combined with the self-centering 135° split point, gives you pinpoint accuracy. You can place the tip exactly where you want the hole, pull the trigger, and it bites instantly—no wandering, no skating across the surface, and no need to waste time grabbing a center punch and hammer. It is especially effective on curved surfaces like pipe or tubing where standard bits tend to slide off.
Walter has coated these bits with their special bronze SST treatment, which is designed to handle heat. Drilling stainless steel generates a lot of friction, which kills standard bits quickly. The SST coating helps shed that heat and keeps the cutting edge sharp, allowing you to drill more holes per bit. Whether you are working in a tight corner inside a chassis or drilling repetitive holes in sheet metal, the 01H130 delivers the reliability and speed professional welders demand. It cuts clean, leaves minimal burrs, and gets the job done so you can move on to the next weld.
