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 drill cutting insert has a cutting edge at a transition between a side surface and a top side which is formed with n identical cutting corners and n identical partial cutting edges —with nε{3, 4} —extending between the cutting corners. Each of the n partial cutting edges has: adjoining a first cutting corner, a main lip which is straight in plan view of the top side; adjoining the other cutting corner, a secondary lip which is straight in plain view of the top side, and a transition section, via which the main lip and the secondary lip merge into one another and which has a convex section adjoining the main lip and a concave section adjoining the secondary lip. The main and secondary lips enclose on the outside an angle a α

摘要： A cutting head has driven surfaces and includes a head coupling pin that protrudes rearwardly from a head rear surface. The head coupling pin includes guiding and fastening recesses recessed in the pin peripheral surface, the guiding recess opening out to the pin rear surface. A tool holder assembly has a tool holder and an elastic fastening assembly. The tool holder has driving members and a holder coupling hole recessed in a holder base surface. The elastic fastening assembly is disposed in a holder through bore that extends from the holder base surface to a holder peripheral surface. When a cutting tool which includes the cutting head and tool holder is in a fastened position, the head coupling pin is removably retained within the holder coupling hole upon elastic engagement with the elastic fastening assembly.

摘要： A hole-making tool includes a body having a seat, which is delimited by a tangential support surface, an axial support surface, and a radial support surface. A cutting insert is fixed in the seat. A pair of female- and male-like securing means is arranged in the interface between the tangential support surface of the seat and the underside of the cutting insert. The female-like securing means includes a guide surface. The male-like securing means is spaced from the guide surface to form a gap between the securing means when the cutting insert is pressed against the axial and radial support surfaces. If the feeding direction of the tool is reversed, the cutting insert may become detached from the seat and the securing means is activated to direct the cutting insert inward toward the radial support surface to prevent the peripheral portion of the cutting insert from scratching the generated hole.
摘要翻译：制孔工具包括具有座的主体，其由切向支撑表面，轴向支撑表面和径向支撑表面限定。切削刀片固定在座椅中。在座椅的切向支撑表面和切削刀片的下侧之间的界面中布置有一对阴型和阳型固定装置。阴型固定装置包括引导表面。当切削刀片被压靠在轴向和径向支撑表面上时，阳型固定装置与引导表面间隔开以在固定装置之间形成间隙。如果工具的进给方向反转，则切削刀片可能会从座椅脱离，并且固定装置被启动以将切削刀片向内朝向径向支撑表面引导，以防止切削刀片的周边部分划伤所产生的孔。

摘要： A cutting insert for use in a drilling tool includes two end faces disposed perpendicular to an insert axis and a plurality of side walls connecting the end faces. Supporting surfaces for bearing against corresponding mating supporting surfaces of a cutting insert receptacle of the drilling tool are formed on at least two of the side walls arranged in a rear region of the cutting insert. A main lip for machining a workpiece to be drilled is formed on at least one side wall arranged in a front region of the cutting insert. The side walls having the supporting surfaces are arranged in such a way that the cutting insert can be inserted into a trigon cutting insert receptacle in an accurately fitting manner.

摘要： A thread tap adapter for interfacing a driving device with a thread tap to assist in the engagement of the driving device to the thread tap. The thread tap adapter having a retention element for engaging the thread tap at a position remote from the drive portion of the thread tap to maintain the engagement of the thread tap adapter to the thread tap. The retention element also provides a secondary transfer point by which the rotational force applied to the thread tap adapter by the driving device is more efficiently transferred to the thread tap. The thread tap adapter can also comprise at least one radially extending flanges for engaging the driving device and prevent the driving device from inadvertently slipping off the adapter by sliding axially along the thread tap adapter.
