Fly cutter/tooling for the 2.2kw spindles

[routercnc]

Hi Lee,

For wood the wealdon tool would be fine. I've used 18mm 2 flute carbide tipped cutters with no issues on wood. I'm sure you could go higher.

But I think for skimming aluminium the flycutter styles pictured above would be hard on the spindle bearings with the interrupted cut, and you would need to run at a high rpm (due to the limited torque) which would be way too fast for the surface speed. I've not tried this, just my thoughts on it.

If you do make/buy a flycutter style tool I'd be tempted to keep the radius down. Larger radius also amplifies any out of tram on the spindle.

My method is a 6mm 2 flute carbide and lots of patience. If you are going for the 2.2kW then you can go up to ~12mm.
