Hi. I am new to milling. I just purchased the harbor freight unit and I have had terrible luck buying decent end mills. I will mainly be milling 1/4 thick 6061 aluminum. I want to mill using a 1/4 end mill a slot 3" to 4" in length all the way through so a 1/4-20 bolt can slide. I see where you can get center cut end mills and make one pass cleanly. I don't want to spend a bank full of cash for a good set. But so far I am not having any luck.
Any help I would greatly appreciate. Thank you
also I may even try and use 1/4" and 1/2" lexan
