CNC3D CNC Bits, feeds and speeds

Hi guys- Just wondering if anyone can recommend feeds and speeds for some of the typical bits for cutting various types of wood (soft ply, structural ply, and hardwoods).


I'm running the 1.5kW Spindle with a screw drive machine.

The bits I'm using are:

  1. 6mm 2 Flute Straight Cut Bit

  2. 6mm 2 Flute Compression

  3. 3.175mm 2 Flute Straight Bit

Also interested in Upcut and Downcut bits.

hi jasshrie, We recommend checking out the "FS Wizard" app on the apple and Samsung app stores. It's got a pretty detailed database of feeds and speeds for a variety of end mills. depending on your machine you may need to dial speeds and feeds down by 20% at first to keep things safe. I hope this helps!

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.
