摘要： A drill bit has a tool shank, a center axis, a first cutting region with at least one geometrically defined first cutting edge, the same having a cutting face arranged at a radial distance from the center axis of the drill bit. The first cutting edge forms a countersink angle with the center axis. The drill bit having a chip shaping stage functionally assigned to the first cutting edge formed by the cutting face of the first cutting edge and by a shoulder surface adjoining the cutting face and forming a shoulder angle with the same, wherein the shoulder angle is greater than 90°, and preferably greater than 100°. The cutting face runs at a radial rake angle with respect to an imaginary radial line which cuts the first cutting edge, the same functionally assigned to the cutting face. The radial rake angle is positive.

摘要： A twist drill includes a drill body having a chip flute extending a distance along the drill body. The chip flute has a leading edge and a run-out edge running along the chip flute. The run-out edge is disposed behind the leading edge in a direction of rotation of the twist drill. The chip flute, viewed cross-sectionally in a direction perpendicular to the longitudinal axis, includes a first wall portion and a second wall portion. The first wall portion extends along a curve between the run-out edge and the second wall portion. The second wall portion extends in a straight line from between the leading edge and the first wall portion. The first wall portion and the second wall portion are disposed adjoining one another and together define a J-shaped cross-sectional profile perpendicular to the longitudinal axis.

摘要： A drill in which no positional shift on a drilled hole and no irregularities on an internal wall are formed. A torsion angle of a shaving discharge groove of a drill is set in the range of 30 degrees to 50 degrees. In this manner, a positional shift of a through hole to be drilled can be reduced. In addition, shavings of the drill are properly discharged, and thus, drilling is not precluded by the shavings. Therefore, a printed wiring board having excellent electric connectivity and reliability can be obtained.
