One other thing I'll add about using G10. I have a preference for Kennametal Drill Fix insert drills. They are good for opening a hole at high speed, and they can also be used to enlarge the hole, as a boring bar. I always found it kind of a nuisance to deal with this kind of tool usage in CAM, because for drilling, you want the center of the drill to be the datum, but as soon as you begin using it as a boring bar, then you want the tip of the outermost insert to be the datum.
So with G10, it is possible to switch the datum by loading the change in the X offset right within the program, just prior to the particular usage one intends for the tool. This way, X0 will work for the drilling position, then as one bores the hole larger, the actual bore diameters can be programmed, as soon as the G10 switches the offset for that tool.
