    We had a similar setup where I used to work but the drive and driven weren&#8 217;t so cone shaped. It worked great for tapping. It was pretty speedy and the parts were pretty easy to handle and because it was based on friction you could go fast or slow and I don&#8 217;t recall breaking many #6 , #8 or #10 taps when I used it. It&#8 217;s still there but so much stuff is cluttered around the area it&#8 217;s hard to access now. I don&#8 217;t recall the manufacturer off hand.
