    What do you folks recommend for drilling tiny little position marker holes?

    I'm having a problem of tear-out when I drill holes for position markers in the upper fret positions of a slotted fretboard. I do okay repairing the damage but I'd like to avoid the problem.

    Elevate makes two tools that would be handy, I haven't used them and NFI.
    You could make a version of the hole drilling jig, and then use a solid carbide downcut endmill in the jig for perfectly clean cuts.

    Endmills and similar centerless bits will walk unless you are set up in a rigid machine, like a small mill, but will make a clean hole. Plain twist drills (59 degree) will stay centered, but will splinter. One technique in any type of wood drilling is to clamp a sacrificial piece tightly against the work, or even clamp a jig, meaning some piece of metal with the same size hole in it. Depending on the wood, even a piece of masking tape could be enough. There are also tiny mills for Dremel tools with 1/8 shank, but again, setup has to be very tight.
    However, I have no luthier experience, so get other replies.

    Are you currently using brad point drill bits?

    I have never had a problem using twist drill bits, but then I never use electricity either.
