It carries the manufacturer grade KC5010 and features a Physical Vapor Deposition (PVD) applied TiAlN coating, which provides thermal resistance and wear protection during demanding threading operations. The insert runs at 4 threads per inch (TPI) and has a 1\/2 inch inscribed circle diameter. At 0.1880 inches thick, it seats in standard LT22ER-style toolholders. This insert is used by machinists and turning specialists working in oil and gas, energy, or heavy-equipment sectors where API-standard threaded connections are required.\u003c\/p\u003e\u003cp\u003eThis insert is suited for precision external threading of API Rotary Shoulder Connections on components such as drill collars, subs, and other downhole tubular fittings. The right-hand cutting orientation matches standard lathe rotation for external thread profiles. The KC5010 carbide grade with TiAlN PVD coating is matched to threading applications involving alloy steels and high-strength materials common in oilfield manufacturing environments. It is sold individually with a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction in KC5010 grade for wear resistance in demanding threading operations\u003c\/li\u003e\n\u003cli\u003eTiAlN coating applied via PVD process for thermal protection and extended tool life\u003c\/li\u003e\n\u003cli\u003eRight-hand external thread geometry at 4 TPI for API Rotary Shoulder Connections profiles\u003c\/li\u003e\n\u003cli\u003e1\/2 inch inscribed circle with 0.1921 inch hole diameter for secure clamping in compatible toolholders\u003c\/li\u003e\n\u003cli\u003eInsert style 22ER for use in standard LT22ER-designated toolholding systems\u003c\/li\u003e\n\u003cli\u003eThickness of 0.1880 inches (4.64mm) for consistent seating and repeatable thread form\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in LT22ER-style laydown threading toolholders.
