01H132 - Walter 1/2 Hex Sst Stub Drill

The Welder's Choice for Tough, Tight Drilling

For professional welders and fabricators, a drill bit isn't just a tool—it's a problem solver. The Walter 01H132 1/2" Hex SST Stub Drill is built to handle the realities of metal fabrication, where space is often limited and materials are unforgiving. Known as a "stub" drill, its shorter length is its greatest strength. Because it is shorter than a standard drill bit, it is far more rigid and resistant to snapping when you lean into a cut. This makes it the perfect choice for drilling out spot welds or making holes in chassis frames where a long bit would flex and break. It also allows you to fit your drill into tight corners and cramped spaces inside weldments that standard bits simply can't reach.

One of the biggest annoyances when drilling sheet metal or stainless steel is the bit "walking" across the surface before it starts to cut, ruining the finish. The Walter SST Stub Drill solves this with a precision 135° split point. This aggressive tip geometry centers itself the moment it touches the metal, allowing you to drill exactly where you need to without wasting time with a center punch. It cuts fast and clean, leaving minimal burrs, which means less time spent deburring and grinding after the hole is drilled. The bronze SST surface treatment helps the bit run cooler, preventing it from burning up when you are drilling through hard stainless steel or aluminum.

The 1/2" hex shank is another feature designed for the real world. We've all had a round shank bit spin in the chuck just when the going gets tough. The hex shank on this Walter bit locks positively into your drill chuck or impact driver, ensuring 100% of the torque goes into the cut. Whether you are installing rivets, prepping for bolts, or running wiring through a bulkhead, this bit delivers the performance you need. It is tough enough to handle daily abuse in the shop or on the truck, making it a reliable partner for mild steel, thin gauge sheet metal, and non-ferrous applications.
