耐磨切削刀具
摘要：
一种切削刀具包括一个切削刀具本体，该切削刀具本体具有一个轴向前端、一个轴向后端、一个邻近该轴向前端的头部以及一个邻近该轴向后端的柄部。该头部包括一个局部截头圆锥形部分，该局部截头圆锥形部分具有一个第一侧向刃和一个第二侧向刃；一个第一侧表面，该第一侧表面具有一个第一侧向过渡刃和一个第一终止刃，其中该第一侧向过渡刃与该局部截头圆锥形部分的第一侧向刃相邻接；以及一个第二侧表面，该第二侧表面具有一个第二侧向过渡刃和一个第二终止刃，其中该第二侧向过渡刃与该局部截头圆锥形部分的第二侧向刃相邻接，并且其中该第一终止刃与该第二终止刃相邻接从而形成一个切削刃。该切削刀具还包括一个硬质切削尖端。

A cutting tool includes a cutting tool body having an axial forward end, an axial rearward end, a head portion adjacent the axial forward end and a shank portion adjacent the axial rearward end. The head portion includes a partial frusto-conical portion having a first lateral edge and a second lateral edge; a first side surface having a first lateral transition edge and a first terminal edge, wherein the first lateral transition edge is adjoined to the first lateral edge of the partial frusto-conical portion; and a second side surface having a second lateral transition edge and a second terminal edge, wherein the second lateral transition edge is adjoined to the second lateral edge of the partial frusto-conical portion, and wherein the first terminal edge is adjoined to the second terminal edge to form a cutting edge.
