Walter SST+ 1/16-Inch Cobalt Drill Bit for Stainless Steel

The Welder's Choice for Stainless Steel Drilling

For welders and fabricators, drilling through stainless steel is often a necessary but frustrating task. Standard bits burn out, snap, or wander, wasting time and material. The Walter 01A504 1/16" SST+ Drill Bit is the solution designed to keep your fabrication projects moving smoothly. Infused with cobalt, this bit is formulated to tackle the work-hardening properties of stainless steel without losing its temper. It bites into the metal instantly and cuts cleanly, leaving you with precise holes for rivets, fasteners, or pilot holes for larger bores.

One of the standout features for metalworkers is the 135° split point. When you are in an awkward position under a chassis or working on a vertical pipe, you don't always have a free hand for a center punch. The SST+ bit centers itself immediately upon contact, giving you control and accuracy right from the start. This feature alone saves significant time and reduces the risk of marring the surface of expensive polished metals. The bit's robust core strength also resists breakage, a common issue with smaller diameter bits like the 1/16" size, ensuring you spend more time working and less time replacing broken tools.

Beyond stainless steel, this bit is a powerhouse on mild steel and non-ferrous metals like aluminum. The bronze SST surface treatment and high-flow flutes prevent the gummy buildup often associated with drilling aluminum, ensuring a clean hole every time. Whether you are drilling out spot welds, preparing surfaces for fittings, or fabricating custom brackets, the Walter SST+ drill bit offers the reliability and speed that professional welders demand. It is compatible with all standard portable drills and stationary machinery, making it a universal problem-solver for your shop.
