Festool has recently added a set of aggressive-cutting Forstner-style drill bits that have a new twist – a twist drill to be specific. Yes, these bits feature three interchangeable centers for various applications. You get the normal, shorter point, a longer point to assist in starting angled holes and a twist-drill bit center.
You’ll see in the video below how to use the twist drill to make perfectly aligned holes with guaranteed no tear-out on either side of the work. Each of the interchangeable centers has a tapered end that inserts into the matching tapered center hole in the ZOBO bit. Switching them out is a breeze. I found them to be aggressive cutting devils. Chucked into a drill press, the largest sized bit fed into softwood end grain as fast as I could feed it.
