Thanks all. I saw the mini-writeup here too: Aluminum on the mini-CNC
The recommended bits, and everything on that site, look like flat end mills. Does anyone have any experience with using engraving bits / v-bits on aluminum or brass? (Was watching this video: https://m.youtube.com/watch?v=2cIHCPI27bo though they use a tiny bit of coolant which is out of scope for us) I’m not sure if it’s the DLC coating on the other tips that allow for dry cutting or if it’s due to the other recommendations we’ve gathered from experience.
I grabbed some bits from the recommended site, I’ll find some aluminum to test with before switching to brass.
