Hi guys,
We are trying to cut through 6.5mm and 9mm birch plywood sheets, ideally with a 5mm wide bit (so we can drill 5mm holes in the same pass).
We have purchased a number of different bits, double flute straight .. Up cut spiral etc..

What spindle speed do you think we should be running at? And feed rate also?

Cutting through the wood in 2/3 or three passes is fine!



We are using a 8x4 router, with a max spindle speed of 24'000 rpm (I believe).

Many thanks!
