    摘要： A drill bit for a boring tool comprises a shank configured for engagement with the boring tool and a working tip having a first end attached to the shank and an opposite second end, and a conical helical thread extending substantially continuously from end to end. The thread root may include a rounded portion while the crest may be flat. The configuration of the helical thread, such as the crest width, thread depth, thread angle, cross sectional area and base width are adjusted as a function of the length of the threaded working tip to maximize bending strength and optimize thread wear and operability.

    摘要翻译： 用于钻孔工具的钻头包括构造成用于与钻孔工具接合的柄和具有附接到柄部的第一端和相对的第二端的工作尖端以及从端到端基本上连续延伸的锥形螺旋形螺纹。 线根可以包括圆形部分，而波峰可以是平坦的。 螺纹螺纹的构造，如波峰宽度，螺纹深度，螺纹角度，横截面面积和底部宽度作为螺纹加工尖端长度的函数进行调整，以最大化弯曲强度，并优化螺纹磨损和可操作性。
