    • An insert attaching/detaching type drill enabling the suitable integration of a drill body with a cutting insert. The drill comprises a cross hatch angle between the clamp receiving surface of the cutting insert (2) pressed against the clamp surface of the drill body (1) and the torque receiving surface of the drill body adjacent to the clamp receiving surface while crossing each other and receiving the rotational force of the drill body (1) from a torque transmission surface is formed smaller, within a range of 2°, than a cross hatch angle between the clamp surface of the drill body clampingly holding the cutting insert (2) and the torque transmission surface of the drill body adjacent to the clamp surface while crossing each other and transmitting the rotational force of the drill body (1) to the cutting insert (2).
    • 一种插入式连接/分离式钻头,使钻头主体与切削刀片的合适结合。 该钻头包括在压入钻体(1)的夹紧表面的切削刀片(2)的夹具接收表面与钻孔主体的与夹具接收表面相邻的扭矩接收表面之间的交叉影线角,同时彼此交叉 并且从将扭矩传递面接收的钻头体(1)的旋转力在夹紧夹持切削刀片(2)的钻头夹具面和 所述钻体与所述夹具表面相邻并且彼此交叉并将所述钻体(1)的旋转力传递到所述切削刀片(2)的扭矩传递表面。
