Gundrilling is a highly flexible, efficient and quick method of producing deep or shallow holes. Producing close-tolerance holes with smooth surface finishes, usually in one pass. This often eliminates the need for reaming, honing, or other finishing operations. Less known are the potential advantages of shallow hole and deep hole gundrilling.

6/19 · 2. Choose correct drilling speed. Because drilling at a high speed will encourage heat build up it is important to monitor drilling speed and drill slower. Recommended drilling speed for aluminium varies between 200 and 300 rpm. 3. Reduced pressure Applying excessive pressure is another way to increase heat build up and therefore should be avoided.
