摘要： A cutting tap (20, 40) includes a body (22, 42) having an axial forward end (24, 44) and an axial rearward end (26, 46) and a central longitudinal axis (Z-Z). The body has a fluted section (30, 50) at the axial forward end. The fluted section includes a chamfered fluted section (54) extending from the axial forward end of the body and terminating at a first full cutting thread (70). The chamfered fluted section includes a first cutting thread (62, 66, 68) located a first distance from the axial forward end of the body, and a second cutting thread (62, 66, 68) located a second distance from the axial forward end of the body. The second distance is greater than the first distance. The chamfered fluted section is shaped such that a thickness of a section of material removed by the second cutting thread is smaller than a thickness of a section of material removed by the first cutting thread. A method of making the cutting tap is also disclosed.

摘要： The present invention is directed to a helical drill configuration that allows substantially flat bottomed holes to be machined. At the cutting end of the body member, there are at least two cutting edges that are symmetrically oriented on opposing sides of the rotational axis of the drill. In an embodiment of the invention, first and second cutting edge portions form a continuous surface which provides strength and tool stability. The height of the second portions of each of the cutting edges remains relatively consistent along the horizontal for formation of a generally flat bottom hole. In the embodiment, a center point is defined by two sloped peak surfaces. A central straight chisel edge is formed by the intersection of the two sloped peak surfaces. The first cutting edge section extends from the chisel edge to the second cutting edge section. The first cutting edge section for both cutting edges is formed by symmetrically thinning the two peak surface. In the invention, stress at the center portion of the helical cutting tool is limited by the chisel edge and first sections of the cutting edge near the center portion having a balanced geometry. The balanced geometry of the helical drill also prevents the drill from wobbling and creating deviations in the hole being formed. The chisel edge may blend with a first curvilinear cutting edge and the first curvilinear cutting edge may also have a positive rake to promote cutting.
摘要翻译：本发明涉及允许加工大致平坦的底孔的螺旋钻机构造。在本体构件的切削端处，存在至少两个切削刃，所述切削刃在钻头的旋转轴线的相对侧上对称地定向。在本发明的一个实施例中，第一和第二切削刃部分形成提供强度和工具稳定性的连续表面。每个切削刃的第二部分的高度沿着水平方向保持相对一致，以形成大致平坦的底部孔。在该实施例中，中心点由两个倾斜峰面限定。中央直凿边缘由两个倾斜峰面的交点形成。第一切削刃部分从凿尖延伸到第二切削刃部分。两个切削刃的第一切削刃部分通过使两个峰面对称地变薄而形成。在本发明中，螺旋切削工具的中心部分处的应力受到凿尖的限制，并且切削刃的靠近具有平衡几何形状的中心部分的第一部分受到限制。螺旋钻的平衡几何形状还可防止钻头摆动并在形成的孔中产生偏差。凿子边缘可以与第一曲线切割边缘相混合，并且第一曲线切割边缘也可以具有正耙子以促进切割。
