A cutting tool includes a cutting head and a tool shank, each having an axial abutment surface. One of the two includes a coupling pin, while the other includes a pin receptacle and a clamping through bore that opens out to the pin receptacle. The coupling pin has an engagement groove and the pin receptacle has an engagement ridge. The coupling pin is received into the pin receptacle. The cutting head and tool shank are releasably attached together by a fastening member that passes through the clamping through bore and acts on the coupling pin so that the engagement groove abuts the engagement ridge and the axial abutment surfaces on each part abut each other.

A cutting tool includes a replaceable cutting head including a forward cutting portion and a rearward mounting portion and a head through hole extending therethrough. The mounting portion includes a male coupling member. The male coupling member includes a conically shaped head abutment surface. The cutting tool includes a female coupling member including a conically shaped forward holder abutment surface and an internal thread. The cutting tool includes a fastening member having an external thread. When the cutting tool is in a locked position, the male coupling member is removably retained in the female coupling member by the fastening member located in the head through hole, the fastening member external thread and the holder internal thread being threadingly engaged with each other. The head abutment surface abuts the forward holder abutment surface thereby forming a Morse taper coupling between the male and female coupling members.

A cutting tool has an indexable cutting insert removably secured to a holding portion of an insert holder. The cutting insert has opposing first and second end surfaces with an insert peripheral surface and a central axis extending therebetween, at least two cutting portions, and at least one mounting cut-out. Each cutting portion has a cutting edge formed by the intersection of rake and relief surfaces formed on the insert peripheral surface, one rake surface facing in a first rotary direction about the central axis and one rake surface facing in an opposite second rotary direction. Each mounting cut-out extends between the first and second end surfaces and has spaced apart first and second flank surfaces disposed on a cut-out peripheral surface which is separate and spaced apart from the insert peripheral surface. The first and second flank surfaces face in the first and second rotary directions, respectively.

A cutting tool having a cutting insert releasably retained in insert pocket by a fastening member. The insert pocket has first and second side surfaces. The insert pocket has a base surface which includes at least one male or female type pocket engagement member which includes at least one sloping pocket wedge abutment surface. The insert has first and second side abutment surfaces. The cutting insert has an insert lower surface which includes at least one male or female type insert engagement member which includes at least one sloping insert wedge abutment surface. By virtue of the sloping orientation of the at least one pocket wedge abutment surface and the at least one insert wedge abutment surface, a clamping force applied by the fastening member urges said surfaces to slide over each other so that the cutting insert sits firmly in the insert pocket.

A cutting tool part includes a cutting portion. The cutting tool part further includes a plurality of guide pads projecting radially outwards from the cutting portion. At least the cutting portion and the plurality of guide pads are made through additive manufacturing, the plurality of guide pads being integrally formed with the cutting portion in a unitary one-piece construction. A rotary cutting tool is provided having a cutting insert releasably attached to the cutting tool part.

A tool holder has a holder body, a first clamping member, and a first fastening member. The holder body includes a fixation portion and a mounting portion located rearward of the fixation portion. The fixation portion has a front fixation surface facing in a forward direction, a cylindrical fixation bore opening out to the front fixation surface and extending rearwardly therefrom, and a longitudinally extending primary slot connecting the fixation bore to a fixation envelope surface. The first clamping member occupies a first clamping bore and traverses the primary slot. The first fastening member occupies a first fastening bore which intersects the first clamping bore and opens out to the front fixation surface. The fixation bore has a fixation bore first primary diameter which decreases and increases when the first fastening member is rotated in first fastening and first unfastening directions about the first fastening member axis, respectively.

A cutting tool assembly having a longitudinal axis establishing upward and downward directions, includes a Y-axis parting adaptor mounted onto a holder. The parting adaptor has an insert pocket including a base jaw configured to support a cutting insert. The holder has a holder head portion and a shank portion. The holder head portion has an adaptor pocket in which the parting adaptor is mounted. If the holder shank cross-sectional shape is square or rectangular the forwardmost cutting edge is directly above the forwardmost holder shank surface, and if the holder shank cross-sectional shape is round and a centrally extending holder shank axis extends to the forwardmost cutting edge.

A parting-off tool assembly including a blade holder, a parting-blade mounted to, and clamped by, the blade holder, a cutting insert and a coolant conduit mounted to the parting-blade. The cutting insert defining a cutting-edge width CW and an extended-width cutting plane of the same width. The coolant conduit with an outlet opening out to a first extension portion located within the extended-width cutting plane.

A tool body having a longitudinal body axis has a central body recess recessed in a rear body surface thereof. The recess includes an inner recess surface, and a body recess peripheral surface extending between the inner recess surface and the rear body surface. An integral central pin extends rearwardly from the inner recess surface, and having an integral pin length measured along the longitudinal body axis from the inner recess surface to a rear pin surface thereof. In a circumferential direction about the longitudinal body axis, the body recess peripheral surface alternatingly increases and decreases in distance from the longitudinal body axis, thereby forming a plurality of angularly spaced apart longitudinal axis crests. A tool holder has a protrusion with complementary surfaces to engage the tool body. A fastening member, such as a lock nut, secures the tool body to the tool holder to form a cutting tool.

A cutting tool for thread cutting has a thread turning cutting insert releasably retained in an insert pocket by a fastening member. The thread turning cutting insert has a thread cutting portion having three spaced apart cutting teeth. and a chip forming groove recessed in an insert upper surface. The chip forming groove includes a near-flank groove surface close to the cutting teeth and far-flank grove surface further away from the cutting teeth. The thread cutting portion includes three cutting edges formed at the intersection of the insert upper surface and an insert peripheral surface. Each cutting edge is located on a respective cutting tooth. The thread cutting portion includes three planar land surfaces located on the insert upper surface. Each land surface extends from an entire length of a respective cutting edge to the near-flank groove surface.
