Walter SST+ 29/64 Inch Cobalt Drill Bit for Stainless Steel

Stop Burning Bits on Stainless Steel

Every welder knows the frustration of grabbing a drill bit for a quick hole in stainless steel, only to have it smoke, squeal, and dull instantly. The Walter SST+ 29/64" Drill Bit (01A529) is built to solve exactly that problem. Designed with a heavy-duty cobalt blend, this bit eats through stainless steel, mild steel, and aluminum without losing its edge. It is the go-to choice for fabricators who need reliable performance in the shop or out in the field.

One of the biggest advantages for fitters and welders is the self-centering 135° split point. When you are drilling into a pipe or a piece of structural tubing, you don't want the bit skating across the surface and ruining the finish. The SST+ bites instantly, allowing you to drill accurate holes exactly where you marked them, often without needing a center punch. This saves you time and frustration, especially when working in awkward positions or on ladders.

The "High Flow" flute design is another standout feature. It pulls chips out of the hole quickly, which keeps the bit cooler. Heat is the enemy of any cutting tool, and by keeping the temperature down, Walter ensures this bit lasts longer than standard black oxide bits. The bronze coating further helps by lubricating the cut, meaning you don't have to push as hard to get the job done. Whether you are drilling out broken bolts, prepping for a tap, or making clearance holes, the Walter SST+ is the reliable workhorse you need in your toolbox.
