Abstract

This product is a tap with an oil hole. As shown in the enlarged left side view reference diagram, the oil hole has an axial hole extending in the axial direction of the tap, and radial holes extending radially from the axial hole toward the grooves. Each radial hole penetrates each groove at a position offset in the axial direction along the thread, within a range of one pitch based on the complete thread, as shown in the reference diagram rotated 60° at a time.
