As shown in FIG. 5, in the structure of the first to fourth embodiments, the high-efficiency pick of the fifth embodiment of the present invention has a raised taper tip from the pick head 2 or a ring tap below the boring head 3. A groove 4 is formed in the body or ring body 8 and the second ring cone or ring body 8, and a groove 5 is formed in the holder 9, and a positioning hole 26 is formed in the positioning handle 27 of the cutting head 2.
通过如此的构成, 在实施方式 1-4的技术效果的基础上, 由于形成有刀座 9上的 凹槽 5, 所以可以进一步分解降低截齿头 2的冲切阻力和摩擦力, 进一步提高散热效 果, 又通过在截齿头 2的定位柄 27上形成定位孔 26的方式降低了成本。 With such a configuration, in addition to the technical effects of the first to fourth embodiments, since the groove 5 formed in the holder 9 is formed, the punching resistance and the frictional force of the cutting head 2 can be further decomposed, and the heat dissipation can be further improved. The effect is further reduced by the manner in which the positioning holes 26 are formed in the locating shank 27 of the pick-up head 2.
