摘要： A tool (T) is provided with: a shaft-like tool body (11) having a first end portion (11a) extending along a central axis line (Ot) and attached to a main shaft, and a second end portion (11b) on an opposite side to the first end portion (11a); and a fore end portion (12) connected to the second end portion (11b) of the shaft-like tool body (11). The fore-end portion (12) includes a central portion (13) including a fore-end face (17) of the tool (T), and a plurality of blade portions (14) protruding radially outward from the central portion (13). A cutting blade of each blade portion (14) includes a main cutting blade (15) adjacent to the fore-end face (17). The main cutting blade (15) includes an outline that forms an angle of 30-150 degrees with respect to the central axis line (Ot) in a cross-sectional view including the central axis line (Ot).

摘要： A plurality of dimples (3) are formed on a processing surface (2) of a workpiece. An aspect ratio of the dimples (3) is 5.0 or more and 50.0 or less, the aspect ratio being a ratio of a vertical length (3b) of the dimple in a longitudinal direction to a lateral length (3c) of the dimple in a lateral direction orthogonal to the longitudinal direction.

摘要： Providing a formed rotary cutting tool that restrains occurrence of breakage. At least a first valley portion 44 as a neck portion in which a cutting edge diameter of a peripheral cutting edge 38 is locally minimized is provided with a roughing portion 58b as a fine roughing portion that is different in characteristics from a roughing portion 58a provided in a portion or portions other than the above-described at least the first valley portion 44. For example, where the roughing portion 58b provided in at least first valley portion 44 has characteristics that make cutting chips small, it is possible to restrain clogging of the cutting chips in at least first valley portion 44 and accordingly to advantageously restrain occurrence of breakage. That is, it is possible to provide the christmas-tree cutter 30 capable of restraining occurrence of the breakage.

摘要： An end mill 10 includes a major-diameter shank 11, a cone-shaped connector portion 12 disposed at the end of the shank 11, a minor-diameter body 13 disposed by way of the connector portion 20 coaxially therewith, and a toothed element 15 disposed at the leading end of the body 13; and further includes one installation recess 14 dented slightly in the toothed element 15. To the installation recess 14, a cutting edge 16 is put in place so as to swell in the shape of an arc to protrude from an outer peripheral face of the body 13 . It is possible to form dimples, which are separated away from each other, one by one for every time the body 13 is turned once.

摘要： On the perimeter of a head (14) that is bonded on one end of the shank (12) of a T-shaped cutter, multiple end cutting edge sections (16) with a cutting edge (16a) on the tip side of the T-shaped cutter (10) and multiple upper edge sections (18) with a cutting edge (18a) on the base end side are disposed alternating in the circumferential direction of the T-shaped cutter. The cutting edges (16a, 18a) of the end cutting edge sections (16) and the upper edge sections (18) form an integral structure with the shank (12) and the head (14).
