In the machining world, drilling depths of 10 times the diameter and deeper are classified as deep hole drilling operations, whereby smaller drilling depths can also be produced with the help of gun drills. The positive effects of the gun drilling process are good surface quality, optimized alignment accuracy and low concentricity deviation.
Gun drills from Sandvik Coromant are easy to use and require no pre-setting. Depending on the application, we offer several different types of gun drills to fulfill your machining requirements.
