摘要： An object is to provide a thread forming tap configured to obtain an inside diameter dimension of a female thread having a targeted processing accuracy more easily than in related art. A thread forming tap (1) is a cold forming tap for forming a female thread by causing plastic deformation of a prepared hole of a workpiece, and includes a male thread portion (3) that protrudes in a thread shape in a radial direction. The male thread portion includes at least one protruding portion (5), which includes a plurality of first thread ridges (51) arranged in an axial direction and that protrude in the radial direction and a first root (52) formed between the first thread ridges adjacent to each other in the axial direction, and at least one adjustment portion (6), which is arranged with the at least one protruding portion in one lead of the male thread portion. A distance from an axial center to a section of the adjustment portion corresponding to the first root in the one lead is longer than a root diameter of the first root and shorter than a ridge diameter of the first thread ridge adjacent to the first root.

摘要： A hard coating includes a three kinds of layers that are alternately laminated. The three kinds of layers consist of a single composition layer and two kinds of nanolayer-alternated layers. The single composition layer is constituted by one of an A composition (nitride of AlCrSiα), a B composition (nitride of AlTiSiβ) and a C composition (nitride of AlCr(SiC)γ). The two kinds of nanolayer-alternated layers include nanolayers which are alternately laminated and which are constituted by two of three combinations consisting of a combination of the A composition and B composition, a combination of the A composition and C composition and a combination of the B composition and C composition. The single composition layer has a thickness of 0.5-1000 nm. Each of the nanolayers constituting the two kinds of nanolayer-alternated layers has a thickness of 0.5-500 nm, and each of the two kinds of nanolayer-alternated layers has a thickness of 1-1000 nm.

摘要： A pipe-tapered-thread machining tap has a thread, four spiral flutes and four cutting edges that include a plurality of thread intersection portions at each of which a corresponding one of the four cutting edges intersects with the thread. The thread intersection portions of the cutting edges have four groups, such that each of the four groups has ones of the thread intersection portions that are portions of a corresponding one of the four cutting edges. Every two of the thread intersection portions of each of the four groups is removed, such that, in each of the four groups, at least one of the thread intersection portions that is removed and at least another one of the thread intersection portions that is not removed are alternately arranged in a direction in which a corresponding one of the four cutting edges extends.

摘要： A thread-cutting tap includes: a thread portion having an external thread, and including a chamfered portion and a complete thread portion that is axially adjacent to the chamfered portion; a flute extending from an axially distal end of the tap toward an axially proximal end of the tap; a rake face defined by one of widthwise opposite end portions of the flute; and a cutting edge defined by one of widthwise opposite edges of the flute, so as to be adjacent to the rake face and extend along the flute. The cutting edge is provided with a protrusion portion at least in a radially outer end portion of the chamfered portion, such that the protrusion portion protrudes from the rake face forwardly in the rotation direction and extends along the cutting edge.

摘要： A hard coating for a cutting tool being highly resistant to both wear and seizure; and a cutting tool coated with the hard coating. This hard coating is a multilayer film including two or more of the following layered in alternation: first coating layers including AgaCu1-a; and second coating layers including a nitride, oxide, carbide, carbonitride, or boride containing at least one element selected from among group IVA, VA, and VIA elements, aluminum, and silicon. Since the atomic proportion for the first coating layers is between 0.2 and 0.4, inclusive, the layering pitch of the first and second coating layers is between 0.2 and 100 nm, inclusive, and the total thickness is between 0.2 and 10.0 μm, inclusive, the coefficient of friction and cutting resistance can be reduced by the inclusion of silver in the coating, and provide a hard coating that exhibits superb lubricity and resistance to seizure.
