01B558 - Walter SST+ Cobalt Jobber Drill Bit, Wire Gauge #58

Drill Stainless Steel Without the Headache

Every welder knows the frustration of drilling stainless steel: the bit skates, the metal heats up, work-hardens, and suddenly you've burned through three bits for a single hole. The Walter SST+ Jobber Drill #58 is built to stop that cycle. Designed specifically for the toughest metalworking environments, this bit bites instantly and keeps cutting long after standard bits have failed. If you are fabricating custom stainless parts, repairing heavy equipment, or working with aluminum, this is the reliable drill bit you need in your index.

The secret is in the cobalt blend. Unlike standard black oxide bits that soften under heat, the SST+ maintains its hardness when things get hot. This means you can drill with confidence, knowing the cutting edge will stay sharp. The 135-degree "Speed Tip" is a game-changer for handheld drilling. You can place the tip exactly where you want the hole, pull the trigger, and it penetrates immediately without wandering across the surface. This saves you time on prep work—no more hunting for a center punch for every single rivet hole.

Chip removal is just as important as cutting power. The SST+ features a special flute design that pulls chips out of the hole quickly. This keeps the tip cool and prevents the dreaded squeal of a bound-up bit. Whether you are drilling out broken bolts, prepping surfaces for tapping, or fabricating structural frames, the Walter SST+ delivers clean, round holes with minimal burrs. It is the professional's choice for a reason: it simply works harder and lasts longer, saving you money on replacements and downtime.
