In forming tap , the pilot hole is also enlarged as it becomes larger.
Since the RH number is +0.013mm for every 1 increase,
In the case of STD+3, STD+0.039mm is a guide.
For that reason, please try from a larger size.

PT threaded pilot hole diameter
Straight holes are recommended for pilot holes.
If you want to increase the pilot hole diameter when tapping PT screws than the catalog value, consider that the allowable range is up to +0.3 mm from the catalog recommended value for nomi

The cutting conditions when machining SS400 with TPT, PT1/4, a tap for tapered thread machining for pipes, are as follows:
A cutting speed of 3~6m/min is recommended.
The reference diameter of 13.157 mm is calculated as the tool diameter.
For example, if the cutting speed is 4 m/min, which is within the ra

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.
