| PROBLEM TO BE SOLVED: To provide a cutting tip capable of suppressing generation of burrs and obtaining a smooth finishing surface, a rotary cutting tool mounted with the cutting tip and a cutting method using the tool. SOLUTION: In this rotary cutting tool having a plurality of cutting tips, cutting tips having cutting edges made of single crystal diamond 3A are used as a part of cutting tips and auxiliary cutting edges of the cutting edges are provided with circular arc parts of radii of >=10 mm and <=500 mm. Cutting tips having cutting edges made of high hard materials except single crystal diamond 3A such as diamond sintered body 3B are used as the remaining cutting tips.

| 32 | End mill | JP18387881 | 1981-11-18 | JPS5890413A | 1983-05-30 | MORITA SHIROU; WAKABAYASHI AKIHARU |
| PURPOSE:To improve the wear resistance of a tool by forming a hard coated layer having a thickness of 3-20mu on the surface other than the cut blade flank and the bottom blade part of an end mill, at least on the ditch rake surface of the cut edge, without applying coating onto said both parts described the above. CONSTITUTION:In the blade part 1 of an end mill 10, an outer peripheral flank 12 and a bottom blade flank 13 are cut and ground, and not coated, but a TiC hard coated layer 15 having a thickness of 3-20mu is formed through the chemical evaporation method on the groove including a rake surface 14. Although the hard coated layer 15 must be formed on the rake surface 14, application of coating onto other parts and onto a grip part 16 is unnecessary. A thickness of layer of 3mu causes reduction of the toughness, and a thickness over 20mu does not improve the wear resistance. | ||||||
