    摘要： A material removing tool includes an elongated shank having a rear end portion arranged to be driven by the motor of a boring or milling machine and a front end portion provided with a coaxial stub which is received in a socket between two legs of an adapter which carries the cutting implement. At least one of the legs has a radial hole which is in near register with a tapped bore of the stub. The shank portion of a screw, whose head bears against a conical surface surrounding a portion of the hole in the one leg, meshes with the threads in the tapped bore of the stub to urge the rear edge faces of the legs against complementary surfaces provided on two shoulders forming part of the front end portion of the shank. This enhances the resistance to bending stresses and prevents wobbling or vibration of the adapter relative to the shank. The external surfaces of the adapter and shank are formed with longitudinally extending grooves for evacuation of shavings or chips from the locus of removal of material from a workpiece. The diameter of the hole exceeds the diameter of the tapped bore, and the axis of the tapped bore is nearer to the shoulders of the shank than the axis of the hole. The head of the screw has a conical peripheral surface whose inclination is the same as that of the conical surface bounding the above-mentioned portion of the hole in the one leg. A second screw can be provided to secure the other leg of the adapter to the stub. The socket of the adapter and the stub can be stepped to further enhance the resistance to bending stresses.

    摘要翻译： 一种材料去除工具包括细长柄部，其具有布置成由钻孔或铣床的电动机驱动的后端部分，以及设置有同轴短截线的前端部分，其接纳在适配器的两个支腿之间的插座中， 切割工具。 至少一个腿部具有径向孔，该径向孔与短截线的螺纹孔近似对准。 螺钉的柄部分，其头部靠在围绕一个腿部中的孔的一部分的圆锥形表面上，与该短截线的螺纹孔中的螺纹啮合，以将腿部的后边缘面抵靠在 两个肩部形成柄的前端部分的一部分。 这增强了抗弯曲应力的阻力并防止适配器相对于柄的摆动或振动。 适配器和柄的外表面形成有纵向延伸的凹槽，用于将屑或碎屑从工件移除材料的场所排出。 孔的直径超过螺纹孔的直径，并且螺纹孔的轴线比孔的轴线更靠近柄的肩部。 螺钉的头部具有锥形周面，其倾斜度与限定一个支腿上述孔的上述部分的圆锥形表面的倾斜度相同。 可以提供第二螺钉以将适配器的另一个腿固定到短截线。 适配器和短截线的插座可以是阶梯式的，以进一步增强抗弯曲应力。
