It carries the KCU10 manufacturer grade with a PVD-applied AlTiN finish, providing elevated wear resistance and thermal stability during threading operations. The insert is right-hand oriented, covers a pitch range of 8-16 TPI, and fits Size 3 Top Notch toolholders. Machinists and CNC operators use this insert in production threading where consistent thread form and extended tool life are required. At 0.1949 inches thick with a 0.0065-inch corner radius, it delivers precise thread geometry on each pass.\u003c\/p\u003e\u003cp\u003eThis threading insert is suited for internal and external buttress thread applications in metalworking environments, including aerospace, oil and gas, and general machining operations where American Buttress thread profiles are specified. It is intended for use in CNC lathes and turning centers equipped with compatible Top Notch series threading toolholders. The AlTiN coating makes it a strong candidate for dry or semi-dry cutting conditions and harder workpiece materials. Minimum order quantity is 5 pieces, sold in single-piece packaging per unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCU10 carbide grade with PVD AlTiN coating for wear resistance at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003eAmerican Buttress thread form, covering 8-16 TPI pitch range\u003c\/li\u003e\n\u003cli\u003eRight-hand insert orientation, compatible with Size 3 Top Notch toolholders\u003c\/li\u003e\n\u003cli\u003eHandles both internal and external threading in a single insert style\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0065 inches for accurate thread root geometry\u003c\/li\u003e\n\u003cli\u003ePart of the Top Notch series for secure, repeatable insert indexing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Kennametal Top Notch series Size 3 threading toolholders accepting NTB-style inserts in right-hand configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThreading inserts should be installed by a qualified machinist or CNC operator with the machine fully stopped and the toolholder secured in the turret. Ensure the toolholder pocket and seating surface are clean and free of chips before seating the insert. Torque the clamp screw according to the toolholder manufacturer specification.
