If it’s a plate, scope mount or something similar you want to mouth, if you can, clamp whatever it is where you want it mounted and use it as a template / guide for drilling. Small taps are very easy to brake. Go slow, make sure your tap is true vertically and horizontally, use oil and make sure you turn the tap ¼ turn counterclockwise ever time you make a clockwise revelation.
