    摘要： A cutting tool including a cutter head and a holder. One of the cutter head and the holder has a recess formed in its axial end portion and defined by its circumferential wall. The other of the cutter head and the holder has a protrusion formed in its axial end portion, such that the cutter head and the holder are detachably attached to each other, with the protrusion being introduced in the recess by an axial distance. The above-described one has coaxial holes formed in the circumferential wall. The above-described other has an engaging surface which is recessed from an outer circumferential surface of the protrusion and which is held in engagement with a pin that is received in the coaxial holes. Each of the coaxial holes has an axis which is inclined, with respect to a plane perpendicular to an axis of the above-described one, in a direction causing the above-described axial distance to be increased by a cutting resistance generated in a cutting operation.

    摘要翻译： 一种切割工具，包括刀头和保持器。 刀头和保持器中的一个具有形成在其轴向端部中并由其周向壁限定的凹部。 刀头和保持器中的另一个具有形成在其轴向端部中的突起，使得刀头和保持器可拆卸地彼此附接，其中突起被引入凹部中轴向距离。 上述一个在周壁上形成有同轴孔。 上述另一个具有从突起的外周表面凹陷并且与容纳在同轴孔中的销保持接合的接合表面。 每个同轴孔具有相对于垂直于上述轴的平面的轴线，在通过切割操作中产生的切割阻力使上述轴向距离增加的方向上倾斜 。

    摘要： A hole cutter machine tool combines the characteristics and properties of a low-cost hole saw with the speed and performance of an annular cutter. The hole cutter comprises a cutter ring portion similar to an end portion of existing annular cutters with a carrier portion similar to the cup of a hole saw. In one embodiment the hole cutter has a threaded aperture which enables use with a standard hole saw arbor or with a replaceable arbor having an annular cutter shank. An embodiment of the method of making the hole saw includes a joining process in which the cutter ring is simultaneously attached to the carrier portion and heat treated.
