    摘要： A cutting tool key (100) suitable for mounting and extracting a cutting insert (22) into and from an insert receiving slot (42) of a cutting tool holder blade (24). The key (100) includes an elongated protrusion (40) having first and second engagement portions (82,84) with a pivot axis (Ap) formed in the first engagement portion (82). The insert receiving slot (42) has a holder axis extending in a forward-to-rearward direction, and a clamping-jaw surface (80) facing a base-jaw surface (64). The base jaw surface (64) has a holder-passage (66) opening out to the holder's side surfaces, and the insert (22) has an insert-passage (38) opening out to the insert's lateral surfaces. The first and second engagement portions (82,84) engage the holder-passage (66) and insert-passage (38), respectively, with the pivot axis (Ap) in the holder-passage (66). Rotating the key (100) in an extraction direction about the pivot axis (Ap) applies extraction-force (Fe) on the insert (22). Rotating the key (100) in a mounting direction, opposite to the extraction direction, applies a mounting-force on the insert (22).

    摘要： A drilling tool of the loose top type includes a basic body (1) having two bendable branches (15) having inner support surfaces (17) that are resiliently pressable against side contact surfaces (23) of a replaceable loose top (2). The mounting of the loose top is affected by turning-in from an initial position to an operative end position. An edge (40) along each side contact surface (23) then bends out the branches (15) and subjects the same to a spring force that reaches a maximum in a dead position so as to then decrease somewhat up to the operative end position. During the final phase of the rotary motion, the operator obtains - in a tactile and/or auditory way - confirmation of the loose top indeed reaching its operative end position.

    摘要： A face grooving tool body (51), comprising a blade portion (52) comprising a top surface (53), an opposite bottom surface (54), a first side surface (55) and an opposite second side surface (56), a front end (57) and an opposite rear end (58), a longitudinal axis (A1) of the blade portion (52) coinciding with a primary cutting feed direction (F1) of the blade portion (52), an upper blade portion (61) associated with the top surface (53) and a lower blade portion (62) associated with the bottom surface (54), wherein the upper and lower blade portions (61, 62) are separated by a slit (59). The second side surface (56) of the lower blade portion (62) is curved around a second side surface axis of curvature (A4) parallel to the longitudinal axis (A1), wherein a key hole (66) is formed in the blade portion (52). The slit (59) comprises a slit portion (68).
    A distance (71) from the bottom surface (54) to the slit portion rear end (70) is greater than a distance (72) from the bottom surface (54) to the rear slit end (60). The slit portion (68) is concave or substantially concave in a side view.

    摘要： The invention relates to a tool (10) for machining a workpiece, comprising a cutting insert (12) and a tool holder (14), which has a main body (15), an upper clamping finger (16), and a lower clamping finger (18). The main body (15) extends predominantly along a longitudinal direction (x) from an end (22) on the holder side to an end (24) on the workpiece side. At least one part of the lower clamping finger (18) projects over the end (24) of the main body (15) on the workpiece side. The upper clamping finger (16) and the lower clamping finger (18) together form a receptacle for the cutting insert (12), in which the cutting insert (12) can be secured by means of an actuating element (20) in such a way that the upper clamping finger (16) exerts a clamping force on the cutting insert (12) via an upper clamping surface (30) disposed on the upper clamping finger. At least one part of the upper clamping surface (30) when viewed in the longitudinal direction (x) is disposed between the end (24) of the main body (15) on the workpiece side and the end (22) on the holder side, and a resulting force vector (44) of the clamping force acts in a region which when viewed in the longitudinal direction is located between the end (24) of the main body (15) on the workpiece side and the end (22) on the holder side. The projecting part of the lower clamping finger (18) has a substantially crescent-shaped or arcuate cross-section.
