管用テーパタップの加工深さはどれくらい？ | オーエスジー

What is the processing depth of tapered taps for pipes?

The number of reference diameter positions in the catalog is a guide to the machining depth.

Example: Processing depth of tapered taps for pipes PT3/8

Tapered tap TPT for pipes (long thread type) The machining depth for machining PT3/8 threads is 21 mm.

Tapered Taps for Pipes S-TPT (Short Thread Type) The machining depth for PT3/8 threads is 14 mm.

* Using the above depth as a guide, adjust the depth at which the gauge passes each time you replace the tap.
