... economically by other processes, such as drilling, boring, or core drilling. When more than 0.5 mm (0.020 in.) on diameter must be removed from a hole less than 50 mm (2 in.) in diameter, special reaming methods or boring is usually considered. Special reaming methods may include the use of gun reamers...

...). In addition, diamond-tip, coolant-fed gun drills have achieved even higher productivity gains with much better tool life in holes up to eight times diameter. Thread forming taps have the longest tool life and can be run at speeds to 20 m/min (70 sfm). They also produce stronger threads than thread cutting...
