01A519 - Walter SST+ 19/64" Cobalt Blend Drill Bit

Reliable Drilling for Tough Metals

For welders and fabricators, there is nothing more frustrating than a drill bit that dulls halfway through a job, especially when working with hardened materials like stainless steel. The Walter 19/64" SST+ Drill Bit (SKU: 01A519) is the solution to this common shop problem. Built with a powerful cobalt blend, this bit is specifically engineered to bite into hard metals and keep cutting long after standard bits have failed. The cobalt content provides the necessary heat resistance to withstand the high temperatures generated when drilling stainless, ensuring the cutting edge stays sharp and effective.

This drill bit isn't just about hardness; it's about smart design. The "High flow" flutes are shaped to pull chips out of the hole quickly and efficiently. This prevents the packing and binding that often leads to snapped bits and ruined workpieces. When you are leaning into a drill on a vertical surface or working in a tight corner, you need a bit that clears its own path so you can focus on the fabrication work, not on fighting your tools. The heavy-duty fully ground body adds to this reliability, offering the stiffness needed to drill straight, true holes every time.

Versatility is key in any welding shop, and the Walter SST+ delivers. It performs exceptionally well on mild steel, aluminum, and other non-ferrous metals, making it a go-to tool for your entire drill index. The bronze SST surface treatment helps the bit glide through material with less friction, which means less heat and less wear on your drill motor. Whether you are drilling out broken bolts, prepping holes for tapping, or fabricating custom brackets, the Walter 01A519 19/64" bit provides the professional-grade performance you need to get the job done right.
