01A511 - Walter 01A511 11/64-Inch SST+ Cobalt Drill Bit for Stainless Steel

The Welder's Choice for Tough Metals

Every fabricator knows the frustration of a drill bit that burns out halfway through a project, especially when working with stainless steel. The Walter 11/64" SST+ Drill Bit is designed to end that frustration. Built for the welder who demands reliability, this bit eats through mild steel, aluminum, and stubborn stainless steel without losing its edge. When you are on a deadline and need to drill out rivets or prep a frame for mounting hardware, you need a tool that works as hard as you do.

The secret to the SST+ performance lies in its cobalt blend construction. Standard bits overheat and lose their temper when drilling hard metals, but the Walter SST+ thrives in the heat. It maintains its cutting edge longer, meaning fewer trips to the tool crib and less money wasted on replacements. The 135-degree split point is a game-changer for freehand drilling. It grabs the metal instantly, so you don't have to worry about the bit wandering and scratching up a polished surface or misaligning a critical hole.

Speed and efficiency are what keep a shop profitable. The specialized flute design on this bit pulls debris out of the hole fast, keeping the cutting tip cool and clear. The bronze surface treatment isn't just for looks; it helps the bit slide through the metal with less resistance, allowing you to drill with less pressure and fatigue. This is particularly beneficial when you are in an awkward position under a chassis or reaching over a welding table.

From custom fabrication to heavy equipment repair, the Walter 01A511 is an essential addition to any welder's arsenal. It turns the chore of drilling hard metals into a quick, clean operation. Stop fighting with dull, inferior bits and upgrade to the industrial standard that professionals trust. With the SST+, you get clean holes, fast results, and a bit that lasts.
