Manufactured in the VK2 micrograin carbide grade, this uncoated insert is engineered for thread milling in superalloy and titanium workpiece materials, where edge integrity and thermal stability are critical. The 6I insert style features a 0.236-inch inscribed circle and conforms to the Standard TM series geometry. It is installed by machinists and CNC programmers running thread mill cycles on machining centers in precision manufacturing environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal UN thread milling in materials classified under ISO N  -  primarily superalloys and titanium. The uncoated micrograin carbide substrate performs well in applications where coated inserts may experience adhesion or edge buildup. Thread mill inserts of this type are used in aerospace, medical device, and defense manufacturing where UN thread standards per ANSI B1.1:74 are required. Each package contains one insert; the minimum order quantity is 10 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eVK2 micrograin carbide grade for superior edge sharpness and wear resistance in difficult-to-machine materials\u003c\/li\u003e\n  \u003cli\u003eUncoated substrate reduces built-up edge when milling titanium and superalloys\u003c\/li\u003e\n  \u003cli\u003eInternal thread configuration at 16 TPI for UN standard threads per ANSI B1.1:74\u003c\/li\u003e\n  \u003cli\u003e0.236-inch inscribed circle fits Standard TM series thread mill holders\u003c\/li\u003e\n  \u003cli\u003e6I insert style for consistent, repeatable seating in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003ePVD-capable grade suitable for both uncoated and PVD-coated application scenarios\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in VARGUS Standard TM series thread mill toolholders accepting the 6I insert style with a 0.236-inch inscribed circle.
