Manufactured under the Top Notch series, this insert carries the NDC insert style with a KC5025 grade carbide substrate and a PVD-applied TiAlN finish coating. It is configured for right-hand cutting at 4 threads per inch (TPI) with a 60-degree included angle. The TiAlN coating provides thermal and wear resistance suited to demanding threading operations in oilfield and energy-sector machining environments. Installation requires compatible Top Notch toolholders and is performed by machinists and CNC turning center operators.\u003c\/p\u003e\u003cp\u003eThis insert is intended for threading API Rotary Shoulder Connection profiles, making it applicable in oil and gas component manufacturing where drill collar, drill pipe, and related tubular connections are machined. It handles both internal and external thread forms and is suited for production environments where consistent thread geometry and tool life are critical. The C2 and C6 material grade ratings indicate suitability for machining steel and other ferrous materials common in energy-sector applications. Minimum order quantity is 5 inserts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide substrate with PVD TiAlN finish coating for extended wear resistance in ferrous thread cutting\u003c\/li\u003e\n\u003cli\u003eNDC insert style, KC5025 manufacturer grade, sized at 4038 insert size\u003c\/li\u003e\n\u003cli\u003e4 TPI internal pitch with 60-degree included angle for API Rotary Shoulder Connection thread profiles\u003c\/li\u003e\n\u003cli\u003eCuts both internal and external thread forms from a single insert style\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting configuration\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0354 inches (0.9 mm) for controlled thread root geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series toolholding systems that accept NDC-style inserts sized 4038.
