摘要： Provided is a ball end mill which is capable of performing both cutting and polishing well and in which cutting resistance at a tip part is low. A ball end mill formed with a plurality of chip discharge grooves 2 on an outer periphery of a tool body 1 from a tool tip toward a proximal end side, and provided with ball-nosed end cutting edges 5, 6 on a crossing ridgeline part between a rake surface 3 of the chip discharge grooves 2 and a spherical tip surface 4 of the tool body 1, said ball end mill having a tool rotation center O on the spherical tip surface 4 and a center-nearing ball-nosed end cutting edge 5 set so that a distance X from the tool rotation center O to the point closest to the tool rotation center O on one ball-nosed end cutting edge 5 in a view of the tool tip is shorter than a same distance Y to the other ball-nosed end cutting edge 6.

摘要： The present invention provides a more practical hard-coated cutting tool having improved cutting performance during finishing so as to obtain a better finished surface. Provided is a hard-coated cutting tool including a tool body (7) coated with a hard coating (4) and having a cutting edge (3) formed on a ridge line intersecting a flank face (1) and a rake face (2). In the hard-coated cutting tool, the thickness h1 of the hard coating (4) on the flank face (1) side and the thickness h2 of the hard coating (4) on the rake face (2) side near the cutting edge (3) satisfies conditions 8 µm ‰¤ h1 ‰¤ 30 µm and 0 ‰¤ h2/h1 ‰¤ 0.5 in a cross-section perpendicular to the cutting edge (3) in a range equal to or less than 0.3 times the tool diameter in the axial direction from the tip of the tool.

摘要： An extremely practical rotary cutting tool in which chips can be excellently discharged even in longitudinal machining. A large number of helical chip discharge grooves (2) are provided in the outer periphery of the forward end of a substantially circular columnar tool body (1), and a bottom blade is provided at each ridge line where a rake surface (3) of a chip discharge groove (2) and a tip clearance surface of the tool body (1) meet. That portion of at least one bottom blade which is close to the outer periphery of the tool is immersed in the axial direction of the tool body (1) to form a non-cut portion (22).
