Walter SST+ 1/2-Inch Cobalt Blend Drill Bit for Stainless Steel

Stop Burning Bits on Stainless Steel

Every welder knows the frustration of grabbing a drill bit to pop a hole in a stainless steel bracket, only to have the bit scream, smoke, and dull before it even breaks the surface. The Walter 1/2" SST+ Drill Bit is the solution to that headache. Built specifically for the guys who need to get through tough materials without the hassle, this bit uses a premium cobalt blend that eats through stainless steel, mild steel, and aluminum like butter. It’s designed to bite hard and cut fast, so you spend less time leaning on your drill and more time fabricating.

The secret is in the design and the coating. Walter uses a special Bronze SST surface treatment that acts like a shield for the bit, reducing friction and heat—the two biggest enemies of sharp edges. This means you can drill more holes per bit, saving you trips to the tool crib and money on replacements. The "High Flow" flute design is another game-changer; it pulls chips out of the hole quickly, preventing them from clogging up and overheating the work. This is especially important when you're drilling thicker stock or working in awkward positions where you can't easily clear the hole.

Whether you are drilling out a broken bolt, prepping a flange, or making clearance holes for 1/2-inch hardware, this bit is a workhorse. It’s tough enough to handle the wobble of a hand drill on a job site but precise enough for your shop's drill press. Don't let cheap bits slow down your production or ruin your workpiece. Upgrade to the Walter SST+ and experience the difference that professional-grade tooling makes. It’s the reliable partner you need in your tool bucket for every heavy-duty drilling task.
