    Abstract: A modular drill includes a shank, a retaining pin, a cutting insert, and a locking pin. The shank includes a shank bore having an axial direction leading into the shank bore, and a locking pin opening. The retaining pin includes a retaining pin shaft axially movable positioned with the shank bore, the retaining pin shaft having a locking pin engagement surface. The retaining pin includes a retaining pin head having a retaining pin head engagement surface. The cutting insert includes a cutting insert passage for passing the retaining pin head therethrough; and a cutting insert cavity having a cutting insert engagement surface for engaging the retaining pin head engagement surface. The locking pin is for positioning within the locking pin opening and engaging with the locking pin engagement surface to force the retaining pin shaft to move further in the axial direction.

    Abstract: In one aspect, expansion sleeves for pressure-activated tool holder apparatus are described herein. An expansion sleeve, for example, comprises a first end, a second end and a longitudinal axis extending between the first end and the second end. A first set of fluid chambers are proximate the first end of the sleeve and a second set of fluid chambers are proximate the second end, wherein fluid channels extend along the longitudinal axis to connect radially offset fluid chambers of the first and second sets.

    Abstract: A modular drill includes a drill body, an insert, and a retaining member. The drill body includes a center hole extending through a first surface of the drill body, and a side hole extending at an actuation location through a second surface of the drill body. The center hole and the side hole intersect within the drill body. The insert is moveably disposed in the center hole. The retaining member is threadedly attached to and moveably disposed in the side hole. The retaining member includes a clamp surface and a bump surface. The clamp surface is disposed closer to the actuation location than the bump surface. When the retaining member is rotated in one direction the clamp surface forces the insert into a locked position. When the retaining member is rotated in another direction the bump surface bumps the insert out of the locked position.

    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。
