pt1/8やpt1/4の管用テーパめねじ加工が可能なチップ交換式のスレッドミルはある？ | オーエスジー

Is there a chip interchangeable thread mill that can process tapered threads for PT1/8 and PT1/4 pipes?

Indexable type ( chip interchangeable) thread mills do not have a lineup that can process PT1/8 and PT1/4.

Please use a solid type thread mill for AT-1 tapered threads for pipes.

For steels with a high hardness of more than 45HRC, we recommend the Thread Mill AT-2 with Solid Type end cutting edge and tapered threads for pipes.

Prior to the 2015-2016 catalog, the 1/4 chip size is the size of the chip itself.

It is not a thread size that can be processed.

In the 2017-2018 edition and later catalogs, the insert size symbol is expressed as a number.
