3 Axis CNC router

Make sure your end mill has flutes long enough. I'm using 6mm bits and the flute length is only 15mm.

Good point, 25mm is quite long for a small shank bit.

True. My uncoated carbide 6mm bit also has a 15mm flute but the whole shank is the same diameter so I just go deeper.

If cutting by hand then use 2 flute spiral upcut which you can get in long flute lengths. Wouldn't use 3 flute by hand as you can't control the speed accuratly enough.

My preferred choice for Ali is 8mm 3 flute serrated edge roughing cutter followed with 2 flute with full depth finish pass.
Serrated edge rougher would be good choice for hand routing.

Hi Guys. It has been a long old while since I have been on here. I hope you are all keeping well. For one reason or another my CNC build has taken a back seat for a few years but I am hoping to get back to it...
