I've been building electric guitars for a few years now and gradually improving my workshop. One of the big challenges is to accurately shape the guitar body using templates. At 45 mm thick this has been a problem for my router set up but not any more. With this bit I can cut the full depth in one pass, and, by alternating the bearing used I can always cut with the grain and eliminate tear out on those sharp corners.
OK, so it cost more than my first router but well worth it, truly for me a game changer.
Did I mention it's razor sharp?
