ISCAR took gundrill technology one step further when developing the new CHAMGUN for deep hole drilling. The CHAMGUN is a gundrill that enables the replacement of drilling heads while the driver is still connected to the machine. The ‘No Setup Time’ concept enables quick head changes without the need to remove the drill from the spindle while indexing. The CHAMGUN is the ultimate economical solution for deep drilling. A polyamide plastic key is used for clamping and removing the CHAMGUN head. The drill features an innovative unique pocket which can sustain at least 15 head replacements. The connection between the pocket and tube is by a new welding process for high torque resistance. Each drill pocket can carry a variety of drilling head diameters and head geometries and chipbreakers designed for use on various materials. The end result is excellent straightness and concentricity inside the hole with high hole precision center alignment.
