George,

Your clip did not make in your post. Have a 6061 aluminum project for a friend I am about ready to start so interested your first experience.

Does a great job!

What were the feeds and speeds?

Thanks!

George, don't see it. Currently out of the country and viewing on a tablet (might be the problem). I will check it out when I get home. Thanks for follow up

It is impressive how fast it cuts the 6061 but as a machinist, I think you would get a much nicer finish if you set the cutter another ½” up into the collet, and halved the feed rate.

I would agree. About 30secs. later the bit broke. Next time I will run the feed rate at 50 instead of 100 for a 1/8 bit. This was the settings Terry.

Pass Depth: .0313
Feed Rate: 100
Step Over: .05
Spindle Speed: 21000

Thanks for the info, I just got a few pieces of 1/4" aluminum scrap (3' x 4') and have been waiting for an opportunity to do something with it.
