Walter SST+ Heavy Duty Cobalt Drill Bit - Wire Gauge #47

Reliable Cobalt Drill Bit for Tough Metalworking

For welders and fabricators, a dull drill bit is more than just an annoyance—it's a bottleneck that slows down the entire project. The Walter 01B547 SST+ Jobber Drill Bit (#47) is built to solve this problem. Crafted with a heavy-duty cobalt blend, this bit is specifically designed to tackle the toughest metals found in the shop, including stainless steel, structural steel, and non-ferrous alloys. When you are prepping materials for welding or drilling out rivets, you need a tool that bites instantly and cuts cleanly. The SST+ delivers exactly that, ensuring you spend less time fighting your tools and more time fabricating.

The frustration of a drill bit skating across a piece of pipe or tubing is a thing of the past with Walter's Speed Tip design. This self-centering feature allows you to start drilling exactly where you intend, without the bit walking off the mark. This is particularly valuable for welders working with round stock or in awkward positions where applying heavy feed pressure is difficult. The aggressive cutting action requires less force from the operator, reducing fatigue during long shifts.

Durability is key in a welding environment, and the Walter 01B547 excels here. The bronze SST surface treatment acts as a lubricant and heat shield, preventing the bit from overheating and binding in deep holes. The back-tapered design further ensures that the bit clears the hole effortlessly, reducing the risk of snapping. Whether you are drilling pilot holes or final clearance holes, this #47 wire gauge bit offers the precision and toughness required for professional-grade work. Upgrade your toolbox with a drill bit that matches the quality of your welding.
