CUTTING TAP AND METHOD OF MAKING SAME
Document Type and Number:
WIPO Patent Application WO/2010/045054
Kind Code:
A3
Abstract:
A cutting tap (20, 40) includes a body (22, 42) having an axial forward end (24, 44) and an axial rearward end (26, 46) and a central longitudinal axis (Z-Z). The body has a fluted section (30, 50) at the axial forward end. The fluted section includes a chamfered fluted section (54) extending from the axial forward end of the body and terminating at a first full cutting thread (70). The chamfered fluted section includes a first cutting thread (62, 66, 68) located a first distance from the axial forward end of the body, and a second cutting thread (62, 66, 68) located a second distance from the axial forward end of the body. The second distance is greater than the first distance. The chamfered fluted section is shaped such that a thickness of a section of material removed by the second cutting thread is smaller than a thickness of a section of material removed by the first cutting thread. A method of making the cutting tap is also disclosed.
