    摘要： A tool holder module has a tool holder and a tool holder assembly jig. The tool holder assembly jig has a horizontal supporting seat. A flange recess is formed in the top surface of the horizontal supporting seat and is configured to accommodate a flange of the tool holder. The flange recess has two clamping portions, and each clamping portion protrudes from a respective one of two opposite surfaces of the flange recess and extends linearly from an opening of the flange recess toward a bottom of the flange recess. The two clamping portions are configured to engage with the two clamping recesses to prevent the tool holder from rotating relative to the horizontal supporting seat. The tool holder is selectively mounted on one of the vertical supporting seat and the horizontal supporting seat.

    摘要： An assembly comprises: a chuck, which has a tool-receiving socket, a contact surface, and a screw thread; and a cutting tool, which has a tool shaft, a mating contact surface, and a mating screw thread. In a clamped state, the mating screw thread of the cutting tool is screwed into the screw thread of the chuck, the mating contact surface of the cutting tool is seated against the contact surface of the chuck, and the tool shaft is frictionally torque-transmittingly clamped in the tool-receiving socket. The invention also relates to a chuck of this type and to a cutting tool of this type.

    摘要： A clamping shank for a tool for clamping the tool into a rotary driving clamping device is proposed. The clamping shank comprises a circular shank portion and a pentagonal shank portion adjoining the circular shank portion. Four contiguous side faces of the pentagonal shank portion each form an angle of 90° to each other in a plane perpendicular to the longitudinal axis of the clamping shank. A fifth side face of the pentagonal shank portion forms in said plane angles of greater than 90° with each of the adjacent side faces of the pentagonal shank portion.

    摘要： A shrink fit tool holder assembly has a holder, a tool, and two fastening units. The holder has an axis, an inserting portion, and a fastening hole defined through the inserting portion. The inserting portion has two assembling holes communicating with the fastening hole. Each one of the two assembling holes has an extending axis inclined relative to the axis of the holder. The two extending axes of the two assembling holes are a pair of skew lines. The tool has a shank section inserted in the fastening hole of the holder. The shank section has two engaging grooves. The two fastening units are respectively inserted into the two assembling holes and respectively engage with the two engaging grooves to prevent the tool from sliding or rotating relative to the holder.

    摘要： An efficient twist drill fir layered drilling comprises a drill bit body, wherein the drill bit body comprises a shank portion and an operation portion; the shank portion is connected with the operation portion; the operation portion has a cutting portion at a front end thereof; a plurality of flutes distributed in parallel and at intervals are symmetrically arranged along a flank surface of the cutting portion; the flutes divide main cutting blades into a plurality of first cutting blades and second cutting blades; and connecting lines of the first cutting blades and the second cutting blades form a step-like structure. During drilling, a drill bit of the twist drill requires a decreased drilling force, produces less cutting heat, is positioned easily and has improved processing efficiency so that a processed circular hole has high precision and few burrs at an edge where the drill bit exits.

    摘要： A drill chuck assembly. The drill chuck assembly includes a rapid change mechanism configured to retain a drill bit shank inserted therein. The drill chuck assembly includes a body having a bore with a trilobe cross-section that is configured to receive a triangular and hexagonally shaped drill bit shank, interchangeably. The bore includes a slot positioned in each lobe that slidably contains a detent ball therein. A collar is affixed annularly around the body and defines a channel extending around the body. A sleeve is slidably mounted around the body. The sleeve includes a tapered end that is slidably disposed within the channel and has circular apertures that are in communication with the slots of the bore for reception of the detent balls. The sleeve is spring biased towards the collar, which forces the detent balls against an angular wall within the channel. The angular wall in turn forces the detent balls laterally towards a center of the bore, thereby exerting a force on a drill bit shank inserted into the bore and preventing the withdrawal of the shank from the bore. When the bias force of the sleeve is counteracted by sliding the sleeve about its longitudinal axis, the detent balls move outwardly along the angular wall, thereby relieving the force exerted onto the shank by the wall and allowing the shank to be withdrawn.

    摘要翻译： 钻夹头组件。 钻夹头组件包括构造成保持插入其中的钻头柄的快速更换机构。 钻夹头组件包括具有三角形横截面的孔的主体，其构造成可互换地接收三角形和六边形的钻头柄。 孔包括定位在每个凸角中的狭槽，其中可滑动地包含止动球。 套环围绕主体环形地固定并限定围绕身体延伸的通道。 套筒可滑动地安装在身体周围。 套筒包括锥形端部，其可滑动地设置在通道内并且具有与孔的狭槽连通的圆形孔口，用于接收制动球。 套筒被弹簧偏压朝向套环，这迫使止动球抵靠通道内的角壁。 角壁又迫使止动球横向于孔的中心，从而在插入孔中的钻头柄上施加力并防止柄从孔中撤出。 当通过使套管围绕其纵向轴线滑动来抵消套筒的偏压力时，止动球沿着角壁向外移动，由此减轻由壁施加在柄上的力并允许柄被拉出。
