Walter SST+ Cobalt Jobber Drill Bit - Wire Gauge #51

The Welder's Choice for Stainless Steel

Every welder knows the frustration of burning through cheap drill bits when working with stainless steel. The Walter SST+ Jobber Drill Bit #51 (SKU: 01B551) is built specifically to solve this problem. Designed with the fabrication shop in mind, this bit features a heavy-duty cobalt blend construction that resists the intense heat generated when drilling hard metals. Whether you are prepping pilot holes, drilling out rivets, or fabricating custom parts, the SST+ stands up to the punishment of daily shop use.

Accuracy is paramount in fabrication, and the SST+ ensures you hit your mark every time. The self-centering Speed Tip prevents the bit from "walking" across the workpiece, which is essential when you are drilling into polished stainless or pipe where a slip can ruin the finish. The 135-degree point bites instantly, reducing the feed pressure required and lowering operator fatigue during repetitive drilling tasks. This #51 wire gauge bit (0.0670") is perfect for precision applications where standard fractional sizes just won't fit the spec.

Beyond just hardness, the geometry of the SST+ bit is optimized for chip removal. The deep, high-flow flutes pull swarf away from the cutting edge quickly, preventing the work-hardening that often occurs with stainless steel. Combined with a friction-reducing bronze surface treatment, this bit cuts cooler and faster. Upgrade your drill index with Walter SST+ and experience the difference a professional-grade cobalt tool makes in your fabrication workflow.
