    • A manufacturing method of a clad type router bit is provided to simplify manufacturing facility and prevent the fall of hard metal material in high temperature by precluding silver solder, flux used in a brazing process, and a high frequency heating element. A manufacturing method of a clad type router bit comprises a step of preparing a steel bar(10) having a diameter of an effective cutting edge(15) and a pipe(20) having an inner diameter conforming to the diameter of the steel bar; a step of swaging either end of the pipe in which the steel rod is inserted; a step of completing a clad base material by drawing the pipe up to desired diameter; a step of forming a cutting part(30) and a shank part(40) by machining either end of the clad base material, and thus removing the pipe; and a step of machining the effective cutting edge on the cutting part.
    • 提供一种包覆型路由器钻头的制造方法,以简化制造设备,并通过排除银焊料,钎焊工艺中使用的焊剂和高频加热元件来防止硬质金属材料在高温下的下降。 包层型路由器钻头的制造方法包括准备具有有效切削刃直径的钢筋(10)和具有与钢筋直径相符的内径的管(20)的步骤。 将钢棒插入其中的管的任一端的步骤; 通过将管道拉伸到所需直径来完成包覆基底材料的步骤; 通过加工包覆基材的任一端形成切割部分(30)和柄部分(40)的步骤,从而移除管道; 以及在切削部上加工有效切削刃的步骤。

    • A router bit is provided to improve bonding strength of a cutting part and a shank part by making their bonding surface even and increasing their bonding area. A router bit comprises a cutting blade on the outer periphery; a cutting part(210) made of cemented carbide steel in which a first concave-convex(211a) is formed on one side longitudinal section; and a shank part made of steel in which a second convex-concave(221a) mating to the first convex-concave is formed.
    • 提供路由器钻头以通过使其结合表面均匀并增加它们的结合面积来提高切割部分和柄部分的结合强度。 router刨机刀头包括在外围的切割刀片; 由硬质合金钢制成的切削部分(210),其中在一侧纵向部分上形成有第一凹凸(211a) 以及由钢制成的柄部,在该柄部中形成有与第一凸凹配合的第二凸凹(221a)。
