Built to the ANSI B1.1-1989 standard, this insert is manufactured from submicron-grade solid carbide with a MT7 manufacturer grade coating, delivering consistent performance in precision threading applications. It is suited for CNC lathes and turning centers where tight thread tolerances are required on internal bores. Licensed machinists and CNC operators install this insert as part of a standard indexable toolholder system for high-volume or precision threading work.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in internal threading operations on UN-standard fastener profiles at 16 TPI. It supports both left-hand and right-hand thread cutting, making it adaptable to a range of threading setups without requiring separate tooling for each hand orientation. Typical applications include threading internal bores in metal components across general manufacturing, aerospace, and industrial fabrication environments where UN thread form compliance is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid submicron carbide substrate for enhanced edge stability and wear resistance\u003c\/li\u003e\n  \u003cli\u003eMT7 coated finish for extended tool life in steel and alloy threading\u003c\/li\u003e\n  \u003cli\u003e16 TPI internal UN thread profile conforming to ANSI B1.1-1989\u003c\/li\u003e\n  \u003cli\u003eSupports both left-hand and right-hand cutting orientations\u003c\/li\u003e\n  \u003cli\u003eC12 insert style for use with compatible indexable threading toolholders\u003c\/li\u003e\n  \u003cli\u003eCertified to CE, ISO 9001:2015, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with C12-style indexable threading toolholders configured for internal UN thread cutting.
