    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).

    摘要： A rotary cutting tool (10) includes a shank portion (12), a cutting portion (14), and a plurality of chip-breaking features (34). The cutting portion includes a plurality of blades (18) and a plurality of flutes (20). The blades and flutes extend along the length of the cutting portion and have unequally-indexed spacing. The flutes have a tapered depth along the longitudinal axis. Each blade includes a leading face (22), a trailing face (24), and a land surface (26) that extends between the leading face and the trailing face. A plurality of chip-breaking features (34) having a multi-radius profile are disposed in the land surfaces of the blades and are distributed in an offset chip breaker pattern (32) such that each chip-breaking feature on one blade is not directly behind the chip-breaking features on immediately adjacent blades. The chip-breaking features on each blade are equidistant from each other.
