For 19mm MFC I think I need 22mm or 25mm cutting length? I have seen some 20mm length is that too short?



6mm 1flute down spiral
0.3mm chipload
10k rpm
= 3000mm/min feed
= 3.1 m/s cutter speed

Is that getting better. Now I've lost the cutter speed tables I saw earlier.
What about a compression cutter to prevent chipping that melamine facing?
