Walter SST+ #48 Cobalt Jobber Drill Bit for Stainless Steel

Stop Burning Through Bits on Stainless Steel

Every welder knows the frustration of trying to drill through stainless steel with an inferior bit. It spins, it heats up, and eventually, it snaps or dulls before the job is done. The Walter #48 SST+ Jobber Drill (01B548) is the solution to those headaches. Built with a heavy-duty cobalt blend, this bit is specifically designed to eat through hard metals that destroy standard hardware store bits. Whether you are fabricating a custom stainless exhaust, mounting brackets on heavy machinery, or drilling out broken bolts, the SST+ delivers the bite and durability you need to keep your project moving.

The secret to the SST+ performance lies in its geometry. The Speed Tip is a game-changer for handheld drilling. It centers itself immediately upon contact, meaning you don't have to waste time grabbing a center punch or worrying about the bit skating across your polished metal finish. This is especially useful when drilling into round stock or pipe, where maintaining alignment is notoriously difficult. Once the drilling starts, the aggressive cutting action requires less feed pressure, reducing operator fatigue during long days in the shop.

Durability is further enhanced by the Bronze SST surface treatment and the intelligent body design. The bit features a "High Flow" flute shape that pulls chips out of the hole quickly and efficiently. This is crucial because re-cutting chips is a primary cause of heat buildup and tool failure. By keeping the cutting zone cooler and cleaner, the Walter SST+ stays sharp longer, giving you more holes per bit. Rated for mild steel, aluminum, and stainless steel, this #48 (0.0760") drill bit is a versatile, high-performance addition to any welder's toolbox.
