OVERVIEW

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.

FAQ

A #51 wire gauge drill bit has a diameter of 0.0670 inches (approximately 1.70 mm).

Yes, the cobalt blend material is specifically designed to drill through hard materials like stainless steel and other tough alloys that would damage standard HSS bits.

No, the Walter SST+ features a self-centering Speed Tip that prevents walking, allowing you to start drilling directly on the mark without center punching.

The bronze SST treatment reduces friction between the bit and the material, allowing for cooler drilling temperatures and extended tool life.

Yes, the SST+ works excellently on non-ferrous metals like aluminum, thanks to its high-flow flute design that clears chips effectively.

This drill bit features a 135-degree split point, which is ideal for drilling into harder materials and provides better centering than standard 118-degree points.

The back tapered body reduces the contact area between the bit and the hole walls, minimizing friction and allowing for faster drilling with less power.

Absolutely. The self-centering tip makes it ideal for portable hand drill applications where stability can be an issue.
