It depends on your spindle speed, though if the spindle speed is slow sometimes you can use a bigger cutter to compensate, if it fits the work, and conversely you can use a smaller cutter for faster speeds if the spindle is a non variable speed router for instance.

Some manufacturers make specialized solid carbide router end mills that work for any material of hardness less than bronze. They give a very clean, smooth, fast cut and last a long time but are expensive.

I hope this information isn't too late but if anyone else has encountered problems with a clicking noise in their probotix steppers, I found that this solution helps:

The probotix stepper motor drivers, like the probostepvx, have mode switches to control the step output of the motors. Unfortunately, since the mode switches are actual physical switches, they can not be set to exactly the number of steps that are usually required, because there is a sixteenth separation between the steps set by the switches. However, if you set the mode switches to a step value that is close to the step value set in Mach3, it should eliminate the clicking noise. It worked for me. Another problem is stepper motor jitter, which I haven't completely solved yet but I think is related to an adjustment of the VREF.

Or just contact probotix, they are usually sort of responsive so maybe they could help.
