    • A core cutter includes a tubular body portion and a plurality of cutting blades arranged at a tip end of the body portion at predetermined intervals in a circumferential direction. At least one cutting blade serves as an inner cutting blade, and the remaining cutting blades serve as outer cutting blades. Through grooves penetrate a tip end of the body portion to open toward a tip end side of the core cutter. Each of the cutting blades having the same circumferential-direction size as the through groove. Gullets are configured to discharge the chips, each of the gullets formed by an outer peripheral surface. The cutting blades are welded to through grooves such that a radially inner end of an axial-direction tip end portion of each of the cutting blades coincides with or substantially coincides with a peripheral surface of an axial-direction tip end portion of the gullet.
    • 芯切割器包括管状体部分和沿圆周方向以预定间隔布置在主体部分的尖端处的多个切割刀片。 至少一个切割刀片用作内切割刀片,其余的切割刀片用作外切割刀片。 贯通槽穿透主体部分的前端朝向芯刀的前端侧开口。 每个切割刀片具有与通孔相同的圆周方向尺寸。 齿槽构造成排出芯片,每个齿槽由外周表面形成。 切割刀片通过槽焊接,使得每个切割刀片的轴向前端部的径向内端与齿槽的轴向前端部的周面重合或大致重合。

    • An outer peripheral surface of a tip end portion of the core body has a tapered surface which is thinner toward the tip end and is edged at the tip end. Recesses 2B are formed at an opening peripheral edge of the tip end portion to attach cutting chips 3. A portion of the core body 2 which is adjacent to a forward portion of each of the recesses in the rotational direction is bent radially inward. Each of the cutting chips 3 has a stepped portion such that a radially inner portion 3a of a forward end portion protrudes forward and a radially outer portion of the forward end portion recedes rearward. A radially inner portion of a rearward end portion of the stepped portion is located forward and a radially outer portion of the rearward end portion is located rearward.
    • 芯体的前端部的外周面具有朝向前端变薄的锥形表面,并且在尖端处边缘。 凹部2B形成在前端部的开口周缘部,以安装切屑3.芯体2的沿旋转方向的每个凹部的前部相邻的部分径向向内弯曲。 每个切割芯片3具有阶梯部分,使得前端部分的径向内部部分3a向前突出,并且前端部分的径向外部部分向后退。 台阶部的后端部的径向内部位于前方,后端部的径向外侧部位于后方。
