It's called the WFT for world's fastest trimmer. I saw it in the latest issue of Handloader, called Little Crow to learn more about it and bought it. I've used it in both a hand-held drill and a lathe (my preferred power method.) It is fantastic, trimmed 500 .308 cases in less than two hours and that's with measuring every other case with my calipers, and running a Forster chamfer/deburring device on each case. BTW, it was unnecessary to debur or chamfer. The cuts were nice and clean, and case mouths were square. One thing to be careful of... you have to size the cases first (of course) and if you have any dents on the shoulder of the case, it will trim too long. Other than that, I'm sold on it.
