Manufactured in the Top Notch series with an NTB insert style, it carries a KC730 grade carbide substrate and a Titanium Nitride (TiN) finish applied via PVD coating process. The insert covers an internal pitch range of 8 to 16 TPI and features an included angle of 45 degrees with a corner radius of 0.0065 inches. It is sized as an Insert Size 3 and is suited for use in C2, C3, and C4 material grade classifications. Installation is performed by machinists and toolroom technicians on CNC lathes and manual threading applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in production and job-shop machining environments wherever American Buttress thread profiles are required on internal bores or external diameters. The right-hand cutting geometry makes it appropriate for standard right-hand threading operations. The TiN PVD coating provides a hard, wear-resistant surface that extends tool life across a range of ferrous and non-ferrous materials classified under C2, C3, and C4 material grades. Typical applications include threading operations on pipe flanges, actuator rods, and pressure vessel components where Buttress thread engagement is specified by design.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC730 carbide grade substrate with PVD-applied Titanium Nitride coating for wear resistance\u003c\/li\u003e\n  \u003cli\u003eCovers 8 to 16 TPI range for American Buttress thread standard\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting geometry for standard threading direction\u003c\/li\u003e\n  \u003cli\u003eCompatible with both internal and external threading operations in a single insert style\u003c\/li\u003e\n  \u003cli\u003e45-degree included angle with 0.0065-inch corner radius for accurate Buttress thread form\u003c\/li\u003e\n  \u003cli\u003eTop Notch series NTB insert style for repeatable seating and indexing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use insert for Top Notch series NTB-style threading toolholders accepting Insert Size 3 geometry in American Buttress thread applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInsert installation and indexing should be performed by a qualified machinist with the machine powered down and all spindle rotation stopped before handling.
