Self-Advancing Step-Tap Drill Bit drilling 1" hole in reinforced carbon-carbon composite material

NASA's Johnson Space Center developed this self-advancing, step-tap drill bit. (http://www.fuentek.com/technologies/StepTapDrill.php) Originally developed for Space Shuttle repair (it now flies on every Shuttle mission), this novel, stepped drill bit features a cutting edge that concurrently enlarges a hole as it cuts threads—a feature not available in other stepped drill bits. The drill bit advances itself into the work material similar to a screw, eliminating the need to apply external axial force. This unique technology greatly improves the safety and efficiency of handheld drilling while reducing operator fatigue, making it ideal for high-volume and heavy-duty construction applications and home shop use.

@theflyinwop When the bit is commercialized it won’t be as expensive as you think. The benefits of technology transfer are the dissemination of innovation and reduced costs through the economies of scale you get when you’re manufacturing something in bulk. You can read more about the technology on our Web site. Since it seems I can't include a URL, search for "Fuentek" and "step tap drill" and you'll find it.

That means that the bit cost about 10 grand right? You know dude,if you put a litlle cutting oil on that,it may last more than a few times before you ruin it.
