The solid carbide gun drill is composed of a drill body (drill tip and drill rod are integrated) and a drill handle which are welded into a whole, and can also be made of all solid carbide (drill tip, drill rod and drill handle are integrated). Its stability, efficiency and life span are better than those of welding type. This design can ensure higher reliability and cutting performance, while its higher rigidity and lower torsional vibration can make the tool life longer.
