01K013 - Walter SST+ 13/64 Cobalt Double-Ended Stub Drill Bit

The Fabricator's Choice for Sheet Metal and Rivets

For welders and fabricators, drilling out spot welds or popping rivets is a daily task that demands a tough, reliable tool. The Walter 01K013 13/64" SST Double-End Stub Drill is built specifically for these rigorous applications. If you are tired of snapping long, flimsy drill bits when leaning into a piece of sheet metal, this stub bit is your solution. Its short, stout profile makes it incredibly rigid, allowing you to apply the necessary feed pressure without the bit bending or breaking. This stability is essential when working with hand drills in awkward positions or tight spaces often found in automotive repair and custom fabrication.

This isn't just a standard high-speed steel bit; it is crafted from a heavy-duty Cobalt blend that eats through metal. Whether you are drilling mild steel, aluminum, or hardened stainless steel panels, the cobalt content ensures the cutting edges stay sharp longer, resisting the heat that burns up lesser bits. The 13/64" size is a versatile standard for rivet holes and pilot drilling. Plus, the "SST" surface treatment acts as a built-in lubricant, helping the bit glide through metal and eject chips cleanly, so you spend less time clearing clogged flutes.

The smartest feature for the busy welder is the double-ended design. We all know the frustration of a bit dulling halfway through a job. With the Walter 01K013, you essentially have a backup bit right in your chuck—just flip it around and get back to drilling instantly. The 135-degree split point bites into the metal immediately on contact, so you won't scratch up your workpiece surface with a wandering bit. Upgrade your toolbox with a drill bit that works as hard as you do and delivers two times the life of standard options.
