Walter SST+ 1/32 Inch Cobalt Drill Bit for Stainless Steel

Stop Burning Through Bits on Stainless

Every welder knows the frustration of grabbing a small drill bit for a pilot hole or precision task, only to have it snap or burn up the moment it touches stainless steel. The Walter SST+ 1/32" Drill Bit (01A502) is the solution to that headache. Built for the professional who demands reliability, this isn't your average hardware store drill bit. It is a high-performance tool designed to eat through the toughest metals in your shop without complaining.

The secret lies in the cobalt blend. Standard bits soften when they get hot, losing their edge instantly. The Walter SST+ thrives in the heat, maintaining a sharp cutting edge even when you are drilling through hardened steel or stainless plate. The 1/32-inch size is incredibly precise, making it perfect for delicate work, rivet removal, or creating pilot holes for larger fasteners. With its 135° split point, this bit bites into the metal immediately—no wandering, no skating, and no need to waste time with a center punch.

Walter has also equipped these bits with a unique Bronze SST surface treatment and a "high flow" flute design. This combination acts like a built-in lubricant system, slicking the way for the bit to slide through metal while ejecting chips faster than standard designs. This means less pressure is required from you, and there is less risk of the bit binding and snapping inside your workpiece. Whether you are working on a drill press or using a hand drill in a tight corner, the Walter SST+ gives you the confidence that your bit will finish the job.
