NTC crest turning insert NTC crest turning insert for (P ) 2mm) and fi ner. for (P * 3mm) and coarser.
NOTE: NTC inserts automatically control root to crest dimensions. Therefore, in setting up threading operations with NTC inserts, check the O.D. or I.D. at the thread crest for correct dimensions.

“J” thread note for catalogue The controlled root radius thread form (SAE8879C) is defi ned for the external thread only. To machine the corresponding internal thread, choose any insert that will cut a unifi ed class 2B thread, then bore the minor diameter to size. Refer to SAE8879C and MIL-S-8879C and SAEAS8879D for the correct “J” thread minor diameter values.
