Perfect, thanks! I'll pop in tomorrow.

Hi All- Just an update- I've had a fair bit of success with the CNC3D 4mm x 22mm x 4mm straight cut 2 flute bit. I've been running it at: 1600mm/min @ 20k with 3.8mm DOC for solid Oak 1800mm/min @ 20k with 4.0mm DOC for Birch and F17 hardwood ply 2200mm/min @ ~18.5k with 4.2mm DOC for soft plywoods. (I think I could go faster/deeper). I haven't gotten around to testing the 6mm endmill's limits yet, but will post when I have more info. Note that I'm using the CNC 3D 1500x1500 screw drive build with NightHawk controller and 1.5kW spindle, and using Fusion 360 for my CAM.
