Walter SST+ Heavy Duty Cobalt Drill Bit, #5 Wire Gauge

Stop Walking and Start Drilling with SST+

As a welder or fabricator, you know the frustration of a drill bit that wanders across the metal before it bites. The Walter 01B505 #5 SST+ Jobber Drill Bit solves this problem with its exclusive self-centering "Speed Tip." This advanced point geometry allows you to drill spot-on without the need for a center punch, even on round surfaces or curved pipes. Whether you are drilling out broken bolts, prepping for rivets, or creating clearance holes in heavy plate, this bit bites instantly and cuts aggressively.

Stainless steel is notorious for work-hardening and burning up standard bits, but the SST+ is built to handle the heat. Made with a robust cobalt blend, this bit thrives in high-temperature drilling applications. It cuts through stainless steel, mild steel, and aluminum with less pressure required from the operator, reducing fatigue during long shifts. The bronze surface finish acts as a lubricant, helping the bit glide through the metal while the high-flow flutes eject chips quickly to keep the cutting zone cool.

The #5 size is a specific wire gauge diameter often used for precision fit-ups or specific tapping requirements. With the Walter SST+, you get a tool that is tough enough for the job site and precise enough for the machine shop. The Quick Shank design (on applicable sizes) ensures a solid grip in your drill chuck, preventing the bit from spinning under load. Upgrade your drilling arsenal with a bit that works as hard as you do and stop wasting time with dull, burnt-out tools.
