Re: Thread tap suggestion
Greenfields are good taps. I prefer OSG myself, have a OSG 1/4-20 cut type, helix flute that has over 3,000 holes in steel and still cuts a nice clean thread. The best taps are the ones that are designed and coated for the material you are working with. Taps are one of those areas where you get what you pay for.

Re: Thread tap suggestion
The 3mm tapp I have is likely for steel (IDK), but I have tapped many of holes in aluminum with it. What's a special purpose 3mm tapp for aluminum look like?

Re: Thread tap suggestion
Joe from what I gather , it has to do with the coating . I get at lest 3000 holes with the tin coated and the black I just make sure I oil the tap and keep it clean for every hole . the only reason I brake them , is that darn shake I get . Gets worse when I'm tired ,so I learned to do something else or go to bed
