Walter SST+ 25/64-Inch Cobalt Drill Bit for Stainless Steel

The Welder’s Choice for Drilling Stainless Steel

Every welder knows the frustration of burning through drill bits when working with stainless steel. The work hardens, the bit smokes, and you end up with a dull tool and a half-finished hole. The Walter 01A525 SST+ 25/64" Drill Bit is the solution to that headache. Built with a heavy-duty cobalt blend, this bit is designed to eat through the toughest metals you encounter in the shop, including stainless steel, mild steel, and non-ferrous alloys. The cobalt content gives the bit the heat resistance it needs to stay sharp longer, meaning fewer trips to the grinder and more time fabricating.

Speed and control are critical when you are fitting up a job. This bit features a self-centering 135° split point that bites into the metal the instant you pull the trigger. You don't need to waste time with a center punch; just line it up and drill. The split point design also reduces the amount of pressure you need to apply, which is a huge advantage when you are drilling out of position or on a ladder. Once you are in the cut, Walter's exclusive "High Flow" flute design takes over. It pulls chips out of the hole rapidly, preventing them from packing up and overheating the bit. This keeps the cutting edge cool and prevents the work-hardening effect that often ruins stainless steel projects.

Durability is key in a welding environment. The SST+ isn't just a standard rolled bit; it has a fully ground body that offers superior strength and precision. The Bronze SST surface treatment adds an extra layer of protection, helping the bit glide through the metal with less friction. Whether you are drilling holes for mounting brackets, tapping prep, or general fabrication, the Walter 01A525 gives you the performance you need to get the job done right the first time. Stop fighting your tools and start drilling with the confidence that only a premium cobalt bit can provide.
