摘要： A cutter having a dust-collecting cover capable of avoid-ing damage to a workpiece even if the latter hits a workpiece, and capable of enhancing collecting efficiency of cutting chips. The cutter 1 includes a protection cover 4 covering a part of an outer circumference of the rotary blade 3, and a dust-collecting cover 12 defining cutting chip passage having a suction port 12a opening to a part of the outer circumfer-ence of the rotary blade 3. The dust-collecting cover 12 ex-tends along the outer circumference of the protection cover 4. At least a part of the dust-collecting cover 12 is made from an elastic material.

摘要： An impact tool comprises an end-bit holding section (3a) and a driving source (2). The end-bit holding section is formed with a hole (3a) for receiving an end bit (12), the hole having a center axis defining an axial direction, the hole having one end in the axial direction functioning as an end-bit insertion opening (3c) for passing the end bit therethrough, the hole having a generally polygonal cross section perpendicular to the axial direction. The driving source is configured to rotate the end-bit holding section. An arc-shaped cutout (3g) is formed at each apex angle of the hole in proximity to the end-bit insertion opening such that the arc-shaped cutout has a largest arc dimension at the opening (3c) and the arc dimension decreases gradually from the opening toward another end of the hole in the axial direction.
摘要翻译：冲击工具包括端部保持部分（3a）和驱动源（2）。端部保持部形成有用于容纳端部钻头（12）的孔（3a），该孔具有限定轴向的中心轴，该孔的轴向方向上的一端用作端部钻头插入用于使所述端部钻头通过的开口（3c），所述孔具有垂直于所述轴向方向的大致多边形的横截面。驱动源被配置为旋转末端保持部。在端部插入口附近的孔的每个顶角处形成弧形切口（3g），使得弧形切口在开口（3c）处具有最大的弧形尺寸，并且弧形尺寸逐渐减小从轴向的孔的开口朝向另一端。
