摘要： A multistage bit is provided with a base part having a profile of stepped conical body with its tip cut off, and with a tip drill having a blade B of the smaller diameter than the blade B which is formed on the stage 2 at the foremost end of the base part A, the latter being provided freely detachably at the tip of the base part A. The stopper S for the above multistage bit comprises a ring shaped member having elasticity in the radial direction with its free diameter slightly smaller than the diameter of each stage of the multistage bit, a part of said ring shaped member being cut, and at least one cut end 18 thereof is bent to the center side of the ring so as to be stopped in the vertical groove 19 formed on the outer periphery of the multistage bit, and the height of the ring H is constituted to be equal to or slightly higher than the height of the stage 2.

摘要： Das Werkzeug weist einen sich stufenförmig zu einer Stirn- seite (7) hin sich verjüngenden Kopf (1) auf. Jede Stufe des Kopfes (1) besitzt einen zylindrischen Bereich (4) zum Kalibrieren eines Rohrendes (3) und anschliessend einen kegelförmigen Bereich (6) zum Entgraten des Rohrendes (3). Jede Stufe des Kopfes (1) entspricht einer üblichen Rohrgrösse. Beim Einschieben des Kopfes (1) in ein zu bearbeitendes Rohrende (3) wird in einem Arbeitsgang das Rohrende (3) zuerst kalibriert und anschliessend entgratet . Durch das Kalibrieren am zylindrischen Bereich (4) wird das Rohrende (3) bezüglich der Längsachse (11) des Kopfes (1) zentriert, was ein exaktes Entgraten am kegelförmigen Bereich (6) gewährleistet. Jeder kegelförmige Bereich (6) weist mehrere Schneidkanten (5) auf, welche durch Spannuten (8) gebildet sind. Das Werkzeug eignet sich insbesondere zum Herstellen von Pressverbindungen an Verbundrohren.
摘要翻译：该工具具有朝向端面（7）逐步变细的头部（1）。头部（1）的每个步骤具有用于校准管端（3）的圆柱形区域（4），随后是用于去毛刺管端（3）的锥形区域（6）。头（1）的每个步骤对应于常规管尺寸。当头部（1）被推入待加工的管端（3）中时，首先校准管端（3），然后在一个操作中去毛刺。通过在圆柱形区域（4）处校准，管端（3）相对于头部（1）的纵向轴线（11）居中，这保证在锥形区域（6）处精确去毛刺。每个圆锥形区域（6）具有多个由凹槽（8）形成的切割边缘（5）。该工具特别适用于在复合管上生产压接头。

摘要： A step drill bit includes a cutting head portion with a rear end coupled to a shank portion. The cutting head portion incudes a front cutting tip, a plurality of steps of progressively increasing diameter from the cutting head to the rear end portion. Each step includes a conical tapered portion that flares radially outward from the axis and a generally cylindrical portion that extends axially rearward from the tapered portion. A flute extends through the steps generally parallel to or helically relative to the axis. Primary and secondary cutting edges are formed at junctions between the tapered portions and the generally cylindrical portions and the flute. A depth stop flange extends radially outward from a rearmost step and has a diameter greater than the diameter of the cylindrical portion of the rearmost step. A deburring recess is disposed within or between one of the steps and includes a deburring edge at a junction between the deburring recess and the flute to remove burrs from an edge of a hole.

摘要： An accessory tool includes an effector end and a shank coupled to the effector end. The shank includes a tool engagement portion that is configured to be received within a tool and a reduced diameter portion disposed between the tool engagement portion and the effector end. The shank defines a first length, and the reduced diameter portion defines a second length that is 10% to 45% of the first length.

摘要： A drilling tool (1) for producing a bore in a workpiece is provided, which has a main body (2) and at least a first plurality (3a) of lips (3) made of ultrahard material, which, in order to form a predetermined first bore diameter, are fastened to associated seats in a manner distributed around the circumference of the main body (2). The lips (3) are distributed around the circumference of the drilling tool (1) at irregular angular spacings (ß, β-Δ
3 , ß+Δ
4 ) and each have at least one cutting edge and at least one rake-face-side chip breaker (37) introduced into the ultrahard material and formed as a depression in the ultrahard material.

摘要： A high efficiency step-structured twist drill comprises a drill bit body (2). The drill bit body (2) comprises a shank portion and an operation portion. The shank portion is connected to the operation portion. The operation portion has a cutting portion at a front end thereof. A rear surface (3) of the cutting portion is provided with a plurality of flutes (4) arranged in parallel and spaced apart with each other. The flutes (4) divide a main cutting blade into a plurality of first cutting blades (5) and second cutting blades (6). The first cutting blades (5) and the second cutting blades (6) together form a step structure. When creating a hole, a drill bit of the twist drill requires a decreased drilling force, produces less heat, can be positioned easily, and has improved processing efficiency, such that the drilled hole has a high precision and less burrs at an edge where the drill bit exits.
摘要翻译：一种高效台阶式麻花钻，包括一个钻头体（2）。钻头本体（2）包括柄部分和操作部分。柄部分连接到操作部分。操作部分在其前端具有切割部分。切割部分的后表面（3）设置有多个彼此平行布置且彼此间隔开的凹槽（4）。槽（4）将主切割刀片分成多个第一切割刀片（5）和第二切割刀片（6）。第一切割刀片（5）和第二切割刀片（6）一起形成台阶结构。当创建孔时，麻花钻的钻头需要减小的钻孔力，产生较少的热量，可以容易地定位，并且具有改进的处理效率，使得钻孔具有高精度并且在钻头退出。
