    摘要: A surface-coated cutting tool has a rake face and a flank face, and includes a base material and a coating formed on the base material. The base material has a cutting edge face connecting the rake face to the flank face, and an oxygen concentration of less than or equal to 1 at.% at a depth position of 0.4 µm from the cutting edge face. The coating includes an aluminum oxide layer containing a plurality of aluminum oxide crystal grains. The aluminum oxide layer includes: a first region made up of a region A on the rake face and a region B on the flank face; a second region on the rake face except for the region A; and a third region on the flank face except for the region B. The aluminum oxide layer satisfies a relation: b-a > 0.5, where a is an average value of TC(006) in the first region in texture coefficient TC(hkl), and b is an average value of TC(006) in the second or third region in texture coefficient TC(hkl).

    摘要: Provided is a taper thread-cutting spiral pipe tap for which the occurrence, in the female thread, of gouges and cutting edge marks when tap rotation is stopped is limited. The taper thread-cutting spiral pipe tap 10 has four helical grooves 20. The cutting edge 24 located every specified number of the multiple cutting edges 24, which are located successively along the succession of thread crests 18 of the complete thread portion 14, is removed. As a result, it is possible to obtain a taper thread-cutting spiral pipe tap 10 for which the occurrence of gouges of the inner circumferential surface of a tapered female pipe thread, the occurrence of chip clogging, and the occurrence of cutting edge 24 marks when tap rotation is stopped are limited.

    摘要: A cutting tap is provided which can form an internal thread with high accuracy even when a prepared hole for the internal thread has an inner periphery of which the dimensional accuracy is low. The cutting tap includes thread ridges (5), roots (8) formed between the respective axially adjacent pairs of thread ridges (5), and a plurality of deburring thread grooves (10) arranged at a constant pitch toward the axial front side of the cutting tap from the rearmost ones of the roots (8) in which the deburring thread grooves (10) are formed, and formed such that a groove bottom diameter (d 3 ) of the deburring thread grooves (10) gradually decreases toward the axial front side of the cutting tap. The respective deburring thread grooves (10) have groove bottom diameter (d 3 ) reliefs by which the groove bottom dimeter (d 3 ) gradually decreases from the front side toward the rear side of each deburring thread groove (10) in the rotation direction of the cutting tap, the groove bottom diameter (d 3 ) reliefs being set to be larger than effective diameter (d 1 ) reliefs of the thread grooves (5).
