Running at 5 threads per inch with a 1\/2 inch inscribed circle and a 0.189 inch thickness, this insert is built to cut accurate buttress thread forms in demanding downhole and oilfield pipe applications. The AC50D grade micrograin carbide substrate receives a PVD-applied AlTiN coating for heat resistance and extended tool life when threading cast iron and steel workpieces. Machinists and toolroom operators working on API-spec tubular goods will find this insert dimensionally consistent and ready to run on compatible laydown toolholders.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for internal threading operations on API Buttress thread-form components, including casing, tubing, and coupling connections common in oil and gas production. The 60-degree included angle and single tooth-per-side geometry produce clean thread flanks in medium-to-hard steels and cast iron. It is suited for CNC lathes and turning centers equipped with laydown insert toolholders in the L43 series, where consistent thread geometry is critical to meeting API connection specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide micrograin substrate with AC50D manufacturer grade for wear resistance in ferrous materials\u003c\/li\u003e\n  \u003cli\u003ePVD AlTiN coating provides thermal stability and reduced edge buildup during threading\u003c\/li\u003e\n  \u003cli\u003eInternal API Buttress thread profile at 5 TPI and 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch inscribed circle with 0.189 inch thickness fits L43 series laydown toolholders\u003c\/li\u003e\n  \u003cli\u003eRated for primary workpiece materials including steel and cast iron\u003c\/li\u003e\n  \u003cli\u003eSingle tooth-per-side design for controlled thread form engagement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in L43 series laydown insert toolholders.
