Reply with QuoteIs that carbide tipped, or HSS?
It really depends on what your machine is capable of.
Anywhere from 10,000 rpm and 100ipm to 18,000 rpm and 300ipm.
Assuming the bit is new and/or sharp.

Re: 8 mm straight flute feed ,speed and doc on plyboard
Spiral bits work much better, especially the serrated "ripper" type. I would use an upcut ripper if you can secure the work well. If you need a good finish, you can do a full depth finishing cut with a compression bit.
Re: 8 mm straight flute feed ,speed and doc on plyboard
I use this on a daily basis on a hardwood, 24,000 RPM @ 2000mm/min, it can even cut aluminum and mild steel, on a hardwood a 5mm step per pass is very safe enough, you can run it all day on a 5 pass 25mm hardwood.I run it @ 1mm per pass because our products are very small
