| abstract | As a gun drill, the cutting performance is excellent, the cutting speed can be dramatically increased compared to the conventional one, high cardiovascular efficiency can be obtained, the cutting edge life is greatly extended, and especially for the small diameter, Provides a way to reduce the frequency of flying. Coolant supply path to the front end surface 3a at the tip of the hollow shank portion 1 having the coolant supply path 12 as the coolant supply path 12 having a V-shaped cutting chip discharge groove 11 in the longitudinal direction on the outer surface thereof. In a gun drill equipped with a cutting head 3A having a coolant discharge port 30 communicating with (12), the cutting blade portion 32 of the cutting head 3A is made of cemented carbide (W), and has a cutting hole. The guide pads 5A and 5B in sliding contact with respect to the inner circumference of the structure are made of different materials of higher hardness than the cemented carbide W. n n Gun drill, cutting head, cutting blade, sliding contact, guide pad |
