    Abstract: A cutting insert that suppresses softening of joint material in a joint surface between a sintered body and a base body to improve the joint strength, and that enables size reduction of the sintered body, is provided. The cutting insert includes a sintered body having a cutting edge, and a base body having a leading end where the sintered body is joined via a braze material. The sintered body includes a front surface on a leading side, an upper surface connected to the front surface and forming the cutting edge with the front surface along a connecting edge with the front surface, a bottom surface opposite the upper surface, a back surface opposite the front surface, and two side surfaces. The sintered body and base body are joined together in a joint surface including the bottom surface and back surface of the sintered body. The joint surface in side view has a step-like shape with a leading side thereof being lower than a trailing side thereof.

    Abstract: A cutting insert incorporates a pre-formed discrete cutting tip which wraps around a curved cutting corner of the insert. The cutting tip includes a top layer and a bottom layer made of a relatively harder material than the top layer. In one embodiment, the bottom layer is made of polycrystalline diamond (PCD) or a polycrystalline cubic boron nitride (CBN) material and the top layer is made of cemented carbide. The cutting insert may further incorporate a chip control structure formed in the cutting tip including a plurality of facets formed on each side of a centerline for providing chip control during a cutting operation. The chip control structure can be formed in a two-step process to expose a portion of the bottom layer. The discrete cutting tip can be brazed to the cutting insert prior to forming the chip control structure.

    Abstract: The invention relates to a cutting tool, particularly for use in a tool chuck of a machine tool, including a tool shaft with a center longitudinal axis and a tool head. The tool head is connected to the tool shaft via a positive-locking connection, which locks the movement in the direction of the center longitudinal axis and the positive-locking connection is supplemented by a bonded connection, particularly a soldered connection.

    Abstract: 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.

    Abstract: 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.
