Walter SST+ Cobalt Jobber Drill Bit #45 (0.0820")

Heavy-Duty Cobalt Drill Bit for Stainless and Steel

For welders and fabricators, a dull drill bit isn't just an annoyance—it's a stoppage in production. The Walter 01B545 SST+ Jobber Drill Bit (#45) is built to keep your shop moving. Known as one of the toughest bits on the market, the SST+ series is specifically formulated with a cobalt blend to tackle the hardest materials you face daily, including stainless steel and heavy structural steel. Unlike standard bits that burn out quickly when heat builds up, this cobalt-infused tool maintains its hardness at high temperatures, giving you more holes per bit and less downtime spent at the sharpener or tool crib.

One of the standout features for anyone using a hand drill is the self-centering Speed Tip. We've all experienced the frustration of a drill bit skating across a smooth metal surface, scratching the finish and missing the mark. The SST+ bites into the metal immediately upon contact, eliminating the need for a center punch and ensuring your hole is exactly where you need it. This aggressive starting capability is matched by a "High flow" flute design that pulls chips out of the hole quickly. Efficient chip removal is essential for keeping the bit cool and preventing it from jamming, especially when drilling through thick plate or tubing.

The Walter #45 SST+ also features a bronze surface treatment that you can see right out of the package. This isn't just for looks; it helps the bit glide through metal with less resistance, reducing the physical force you need to apply. Combined with a back-tapered body that prevents the bit from getting stuck, this tool makes drilling less fatiguing and more efficient. Whether you are drilling out broken bolts, fabricating custom brackets, or working on stainless steel piping, the Walter 01B545 delivers the professional-grade performance welders demand.
