I'm getting ready to order a tap to clean out threads in my TR3 while I'm placing an order at mcmaster.com. I need 1/4"- 28 for most holes, correct? Can anyone advise me as to what style of chamfer would be best (taper,plug, or bottoming): https://www.mcmaster.com/#taps/=e9bkge ?
Thanks in advance for any advice,
