What Gary said...I routinely use much lower RPM for simple drilling toolpaths, typically something like 5-6K RPM.

So, in most cases there is more than enough torque to drill small holes right down to 3000 RPM. But in any case it is your job to ensure that the feeds and speeds are proper.
Perfect! Thanks Gary that clears up my miss-understanding.

Thanks Jim. I'm assuming I should try on the lower end to be as close to regular drilling speeds as possible.

Any advice on what I should look out for to indicate I've got the wrong speed? Also can you recommend a good starting place for plunge rate?

Thanks,
William
