摘要：
In an interference fit type cutting tool according to the present invention, a projection and a fitting projection are formed at the rear end of an edge section and at the leading end of a shank section, respectively. A connecting member is provided with first and second holes that have a predetermined interference with respect to the outer diameters of the projection and the fitting projection. The edge section and the shank section are fixed by interference fitting between the first hole and the projection, and between the second hole and the fitting projection. Chatter vibration is reduced by making the edge section and the shank section of a high-rigidity material having a lower coefficient of thermal expansion than that of the connecting member.
摘要（中）：
在根据本发明的过盈配合型切削工具中，突起和配件突起分别形成在边缘部分的后端和柄部的前端。 连接构件设置有相对于突起和配件突起的外径具有预定干涉的第一和第二孔。 边缘部分和柄部分通过第一孔和突起之间以及第二孔和配件突起之间的干涉配合固定。 通过使具有比连接构件的热膨胀系数低的热膨胀系数较低的高刚性材料的边缘部分和柄部来减小抖动振动。
