    CNC not drilling straight in G10

    Hi, I'm using a Uniline 2000 CNC drill machine.

    I am trying to drill straight holes with a 0.8mm drill into 10mm thick G10.

    I'm looking for the perimeters for it to go straight, I can get the holes though but just not straight, it tends to wonder when leaving the material, so the first holes going in are fine, just not at the exit.
    I have it close, but just can't get it exact. I have been using pecking to keep the tool as cool as possible as it drills.

    I have been ranging the feed parameter between 15-30 and the speed/RPM between 60-70.
