May I assume the emc is not in the 40% to 50% range, but rather the =
reletive humidity (RH) of your shop is in that range? If not, no wonder =
your bits don't get hot - you're drilling under water!

All in fun and for the sake of clarity!  ;-)

     Now I'm curious. If I used any thing smaller  than .250 to drill =
no. one pins in the buldoc blocks I'd be hatin life. Are you perhaps =
running the drill speed slower or are you just stronger than Me.?Slower =
speed usually nets a looser fit. I've been currently running drilll =
speeds of 1200 to 1400 rpm.
       I guess we should also factor in the climate variables from =
Calif. to Nashville. We don't get the super low humidity for prolonged =
periods how bout you. Or Humid for that matter.
       I 've been paying closer attention to the emc the block is =
drilled at . I don't want to drill it on either end of the emc spectrum =
but in the 40 to 50% range unless it's going to the desert.

        The C is .242", the D is .246" and the E is .250".   I have used =
an E at=20
    the top, thought it left too little margin for long term safety. =20
