Walter SST+ 7/32 Inch Cobalt Drill Bit for Stainless Steel

Stop Burning Bits on Stainless Steel

Every welder knows the frustration of drilling through stainless steel only to have the bit dull, smoke, or snap halfway through the job. The Walter 7/32" SST+ Drill Bit (01A514) is the solution for fabricators who demand reliability and speed. Built specifically to tackle tough metals, this bit uses a special cobalt blend that withstands the high temperatures generated when drilling hard alloys. This means you spend less time changing out burnt bits and more time fabricating.

The SST+ isn't just tough; it's smart. The 135-degree split point tip is a game-changer for anyone working with hand drills. It centers itself the moment it touches the metal, so you don't need to waste time grabbing a hammer and center punch. This is especially useful when you are in an awkward position or drilling into a round tube where standard bits tend to wander. The bit cuts freely and aggressively, requiring less feed pressure from the operator, which reduces fatigue during long shifts.

Built for the Fabrication Shop

Walter has designed these bits with a "High Flow" flute shape that pulls chips out of the hole rapidly. In welding and fabrication, keeping the heat down is critical to preventing work-hardening in stainless steel. By ejecting hot chips quickly and utilizing a bronze surface treatment to reduce friction, the SST+ keeps cutting where other bits fail. Whether you are drilling rivet holes, pilot holes for tapping, or general clearance holes, this 7/32" bit provides the durability and precision professional welders expect from the Walter brand.
