摘要： A drilling tool of the loose top type includes a basic body having two bendable branches having inner support surfaces that are resiliently pressable against side contact surfaces of a replaceable loose top. The mounting of the loose top is affected by turning-in from an initial position to an operative end position. An abutting edge along each side contact surface then bends out the branches and subjects the branches 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 rotary cutting tool includes a replaceable cutting tip having a cutting portion structured to perform cutting operations on a workpiece and a first threaded portion disposed generally opposite the cutting portion. The cutting tool further includes a generally cylindrical tool body disposed about a central longitudinal axis. The tool body has a first end portion adapted to be coupled to a machine tool and an opposite second end portion having a second threaded portion cooperatively engaged to the first threaded portion. The second threaded portion is moveable with respect to the tool body in a manner that selectively couples the cutting tip to the tool body.

摘要： In the case of a cutting insert, in particular for counterboring and/or countersinking operations, the cutting insert has two longitudinal sides and two narrow sides between an upper side and an underside. A cutting edge is formed between one longitudinal side and one narrow side and runs obliquely in relation to the underside and extends over at least approximately the entire depth of the cutting body. A cutting face running between the upper side and the underside is provided in the longitudinal side that is facing the cutting edge.

摘要： A cutting tool including a body, a blade, a feed shaft, and a locking member. The body defines an axis and is adapted to be received by a spindle of a power tool. The blade is removably supportable on the body and rotatable about the axis for cutting a workpiece. A feed shaft is removably supportable in the body and rotatable about the axis for engaging a workpiece, the feed shaft being mountable in the cutting tool to engage and at least partially restrain the blade. The feed shaft further includes an opening transverse to the axis. The locking member is engageable with the body and with the opening in the feed shaft. Advancement of the locking member into the opening tightens both the blade and the feed shaft to the body.

摘要： A cutting tool holder configured for mounting a cutting insert to form a cutting tool that extends along a central axis and comprises a mounting portion having a seat surface oriented generally perpendicular to the central axis. The tool holder has at least two securing extensions projecting from the seat surface in a direction generally parallel to the central axis. Each of the extensions are formed, at an end remote from the seat surface with a latch portion extending towards the central axis. The latch portion has an under and top surface, both oriented generally transversely to the central axis such that the under surface is disposed between the seat surface and the top surface. Each of the extensions is formed with a side surface extending between the under and side surfaces to form a securing pocket defined between the seat, side, and under surfaces.
