A 4mm 2-flute downcut or a 4mm straightcut should be fine

I use a 4mm 2-flute straightcut, i have rollers to hold the base down, no need for downcut flutes then.

You won't burn bits on polyethylene. Keep the feedrate high and run at high speed (like 18000rpm) for a smooth cut.

A 3mm is scetchy, it will clog up pretty easy.

hello endre, thanks very much for your help.

i had asked to the FREZITE guys ( one of the best and durable routerbits on europ and they have their home page in diferent languages), for straight routerbit for wood in 4mm and they send me 3mm wrong but it works like a ninja sword.

see the photos of the samples i had made:

Thanks

PS: buy your router bit from this guys and you will have the best routerbits you can get. they are a bit expensive, but good as ninja sword
