    I've got some pup templates and the corners are 1/4" radius.
    I can't find any top-bearing bits that small. Do you just use a straight bit and ride the shank against the template? Seems that would destroy the template in short order.

    I typically drill the corner with a 1/4 forstner bit and then ride the template with a 3/8 bearing bit...

    3/16 pattern bits from Amana Tool. Part #47775. These are absolutely priceless bits, I use them with a small trim router, only after the rest of the rout is cut away. You have to be pretty careful not to cook that small bearing.

    Excellent! Thank you.

    THe corners of MM and J pup templates are what I'm dealing with.

    It has always been the "P" templates that were trouble for me
