切断部を多段にわたり形成した溝なしタツプ。 The tap has a tapered chamfer that tapers from the tip to the base, a complete peak that extends horizontally to the expanded diameter side of the chamfer, and a narrow cutting part that reduces the diameter of the complete peak. A pair of chamfered parts, a complete peak part, and a cut part were formed in multiple stages by connecting each part from the base end of the cut part and further connecting the diameter-reduced side of the chamfered part from the base end of the cut part. Tap without groove.
