| titleOfInvention | Cemented carbide drill with excellent breakage resistance |
| abstract | Provided is a cemented carbide drill that exhibits excellent breakage resistance when used for high-speed drilling of metal parts. A cemented carbide drill comprising a groove forming portion and a shank portion, at least the groove forming portion including Co: 3 to 14% by mass as a binder phase forming component and tungsten carbide as a hard phase forming component. When the (111) plane peak intensity of the face-centered cubic structure Co and the (101) plane peak intensity of Co of the dense hexagonal structure are Ifcc (111) and Ihcp (101), respectively, hcp transformation rate = Ihcp (101 ) / {Ifcc (111) + Ihcp (101)} is made of cemented carbide with hcp transformation rate ≧ 0.2 for the outer margin and hcp transformation rate ≦ 0.1 for the cutting edge portion. Drill. [Selection figure] None |
