I was asked about tap and dies for the cigar coupler and tranny size. WHen I measured the ones I use I find that they were m7.35 x.5. THe m7.4 x .5 tap I carry will cut the female threads but is there a need for the Die? I havent had the dies made because the tap is for the Meister Nib #6 feed assembly and did not see a need for them. My question is would this be a useful set? the Die would run about $65.00 or the set of both tap and die would be around $90.00 Is there a need for this as set?
