    Abstract: A tool holder (e.g., shrink fit adapter) with fluid directing passages includes a shank and a fluid/coolant directing structure including one or more nozzles fluidically connected to feeder channels of the shank. The one or more nozzles each include an inner wall and an outer wall configured/shaped to direct fluid/coolant flow both radially inwardly and longitudinally distally and/or to variably modulate fluid/coolant flow around a nozzle outlet of or provided by the nozzle(s) in relation to a longitudinal central axis of the shank. The fluid/coolant directing structure incorporates one of more of: a ring of peripherally located nozzles having geometries/orientations configured to focus and direct thin sheets of fluid/coolant both radially inwardly and distally longitudinally; manifolds for directly feeding nozzle inlets of distally located nozzles; and a nozzle provided by approximately sinusoidally varying surfaces circumferentially disposed about a tool receiving recess of the tool holder for correspondingly variably modulating fluid/coolant flow direction through and exiting from the nozzle.

    Abstract: Hollow shank tool holders including stress reduction features that result in a more reliable stronger tool holder are disclosed. The tool holders include an elliptical undercut contoured relief surface adjacent to the clamping surface to substantially reduce or eliminate a stress point. The elliptical undercut allows for no changes to be made to the clamping surfaces of the tool holder.

    Abstract: A rotary cutting tool including a cutter member having an axial forward end and an axial rearward end. A cutting region is at the axial forward end of the cutter member, and a male threaded portion is adjacent the axial rearward end of the cutter member. A shank member has an axial forward end and a shank bore opening at the axial forward end. The shank bore has an axial shank bore length. The shank bore contains a female threaded portion and an axial rearward shank bore portion axially rearward of the female threaded portion. The axial rearward shank bore portion has a terminal end. When the male threaded portion of the cutter member fully engages the female threaded portion of the shank member, the axial rearward end of the cutter member being spaced a first distance axially forward of the terminal end of the axial rearward shank bore portion.

    Abstract translation: 一种旋转切削工具，其包括具有轴向前端和轴向后端的切割构件。 切割区域位于切割器构件的轴向前端，并且外螺纹部分邻近切割器构件的轴向后端。 杆构件在轴向前端具有轴向前端和柄孔开口。 柄孔具有轴向轴孔长度。 柄孔包括内螺纹部分和在内螺纹部分的轴向后方的轴向后柄孔部分。 轴向后柄孔部分具有终端。 当刀具构件的外螺纹部分完全接合柄构件的内螺纹部分时，刀具构件的轴向后端在轴向后柄孔部分的终端的轴向前方间隔开第一距离。
