    摘要: This invention relates to a boring tool having a cutting insert. The insert has a chip breaker with a base that extends from the secondary cutting edge to the primary cutting edge. The primary cutting edge, which is also referred to below as the major cutting edge, thereby runs diagonally with respect to the insert surface or top face of the indexable insert toward the chip breaker base of the chip breaker. The secondary cutting edge, which is also referred to as the minor cutting edge below and is advantageously straight, descends toward the major cutting edge, as a result of which a wiper geometry is realized on the minor cutting edge. Therefore the major cutting edge and the minor cutting edge preferably form a closed triangle with the chip breaker base.

    摘要: The invention relates to a twist drill, especially for metals. It has a substantially cylindrical basic component (1) divided into a shaft (2) and a cutting section (3), the central longitudinal axis (5) of which is the axis of rotation of the twist drill. Several swarf grooves (4, 4') are made in the cylindrical surface of the basic component (1) which extend spirally and continuously from the shaft (2) to the drill tip (6) and bound a swarf chamber (35). The feature of the twist drill is that its drill core diameter tapers continuously from the drill tip (6) to the shaft (2).
