1 Flute Down Cut
An 1 flute down cut are suitable for both aluminium composite material (a.k.a aluminium composite panel, ACM, alucobond), plastics and wood. Operating in the same manner as the 2 flute down cut, an 1 flute has a single cutting edge and forces chips back down into the material.
- Plastics (ABS, acrylic, HPDE etc)
- Aluminium Composite Materials
Depending on the rigidity of your cnc, you can cut aluminium composite panel with 1 or 2 passes. Also, if you find that using a smaller diameter bit (e.g. 2mm) creates a higher than desired clean up time due to plastic chips packing back into the slot, try a 1 flute up cut for aluminium.
