Step Drill Bit
#4
Hello Good Gentlemen

I believe KOC suggested the use of a step-bit to deburr holes in TUT3 ? Or was it TOT? or both?

I would not worry too much about the use of a metric drill versus an Imperial one, as both come in very similar sizes. For example,1/8" is 3.175mm and likely in most cases one could use a 3mm drill without any issue. The difference is about 5-6%. I might propose that the very common "drill wobble" most consumer-grade tools exhibit would cover this difference?

For a tube socket mounting hole, metric might actually be better since many sockets are metric. otherwise, the clearance hole itself needs to be a small bit larger than the portion of the coket to pass through the hole. If the clearance hole is for the tube itself then any size larger than the tube diameter will suffice, accounting for the rocking or swiveling of the tube needed to gently release it from the socket. I believe a 1" hole is typical here, which is 25.4mm.
