Abstract:
A pipe-tapered-thread machining spiral tap includes a tapered thread portion that is circumferentially divided by flutes into a plurality of lands. Each of at least one of the lands has a cutting edge that extends along a corresponding one of the flutes. The flutes are made of a plurality of spiral flutes that are three, four or five spiral flutes each having a helix angle that is not smaller than 30° and smaller than 50°. A flute width ratio AG/(AG+AL) is 0.3-0.5, where AG represents a central angle which is subtended by each of the flutes and which is defined at a center corresponding to the rotation axis in a cross section that is perpendicular to the rotation axis, and AL represents a central angle which is subtended by each of the lands and which is defined at the center in the cross section.

Claim (Index 2):
The spiral tap according to  claim 1 , wherein\n said spiral flutes consist of four spiral flutes and said lands consist of four lands defined by said four spiral flutes, and said cutting edge is provided in every other of said four lands as said at least one of said lands in a circumferential direction of said spiral tap.
