摘要： A cutting tip having a three-layer laminated structure is provided. The tip is made from a disc-shaped three-layer laminate wherein a second layer consisting of a hard sintered compact of CBN or diamond is sandwiched by a first layer and a third layer consisting of a tool material such as cemented carbide. Prismatic blanks of rectangular cross-section are cut out by cutting the three-layer laminate in strips. Semi-completed tips of a desired shape are obtained by cutting up the prismatic blanks. Desired cutting edges are formed on the semi-completed tips to produce completed tips. Because prismatic blanks are obtained from a three-layer laminate and semi-completed tips are cut out from the prismatic blanks like this, the semi-completed tips can be obtained in large numbers, yield is high, and the manufacturing cost of the tip can be reduced.

摘要： A drill includes a blade portion provided with spiral cutting blades along a cutting direction from a tip end to a rear end, and a shank portion formed consecutively on a rear side of the blade portion. The blade portion includes distal-side cutting blades provided from the distal end of the blade portion along the cutting direction and angled at a constant first torsion angle, intermediate grooves formed at a variable torsion angle that varies gradually from the first torsion angle to a second torsion angle, and rear-side grooves formed at the constant second torsion angle. The rear-side grooves are longer than the distal-side cutting blades in the cutting direction, and the second torsion angle is greater than the first torsion angle.
