I have a bunch of mortises to cut for non rectangular hinges. (think Butler Tray style)
Made myself a perfect template out of 1/2" MDF and then realized I needed a very short bearing guided bit to route the shallow mortises.
Picked up this guy at the local Woodcraft:

Came home and fired it up on a piece of scrap and to my surprise, the bearing is NOT inline with the cutter! The mortise it routed was at least 1/16" smaller than my pattern.
I must be ignorant of something.. Why on earth would a bearing guided bit like this not have the bearing exactly inline with the cutter? My template which fits the hinges perfectly is useless with this bit.
Ended up using my template and a larger bearing guided pattern bit to make a much thicker template so that I could use my much longer bit to cut the shallow mortises and that all worked fine, but what a PITA.
I feel like this new bit is useless as a pattern cutting bit. Very curious to know what I'm missing here, why it's offset. There must be a reason?
