I don't do a lot of rigid tapping on my Haas DM-2, But I do some, and I am looking for some guidelines.
1/4 - 20 threads
6061 Aluminum stock is 1/2 thick
Hole is al the way through the stock.
Questions:
Recommended RPM ?
Should I use peck, or do it all in one pass ?
I'm currently tapping at 600 RPM, and I know this is probably way to slow..... so I figured I would see what other people are doing.
Thanks....
