イトの刃先検出プローブ。 A contactor having a conical recessed hole on the upper surface having a shape that corresponds to the part that cuts the thread flank of a thread cutting tool to be measured in a cutting edge contacting part of a high-precision switch used in a cutting edge position detection device; It is composed of a switch actuator that is always preloaded with a spring and is movable in the switch operating direction, and a steel ball that is disposed between the contact and the switch actuator. A cutting edge detection probe for a thread cutting tool, which has no play and is configured to be able to move slightly in a plane perpendicular to the direction of operation so as to match the center of the thread cutting tool.
