Re: CNC Aluminum: Recommended Speeds/Bits?
I have to post back in this thread to thank all those that recommended the Onsrud single flute bits. It's been a complete night and day difference. It essentially made the difference between our router not being able to cut aluminum at all, and now cutting it beautifully.

I was able to pocket with a 1/4" bit, 20,000 RPM, .090 DOC, 15% stepover, 84 IPM, and it worked very well.

Thanks again!
