Hi, Thanks for that.

We have a system based on this..
http://www.worldofcnc.com/complete-c...ge-p-2669.html

Its has a spindle Elte HF Spindle TMPE 9/2 220v and ''according'' to our quote paperwork is 1.1kw 2400 rpm 220v.

But this doesn't sound right.. i'm sure its spinning nearer 24000 rpm! I'm actually waiting to hear back from the supplier as we've been left with the installed machine and no instructions how to change the spindle speed! It's running off an invertor which controls the speed.

Its all working nicely, but looking to improve and optimise the cut setup.

So going back to the router bits, what style of bit (and width) would you recommend?
I've seen it said that single flute upcut spiral would be good?
Ignoring the drilling of 5mm holes.. so could increase the width of bit for the channeling work.

Thanks again.
James

p.s we are pretty new to this and really appreciate the advice.
