Running at 4 threads per inch with a 1\/2-inch inscribed circle and 0.187-inch thickness, this uncoated P30-grade carbide insert delivers consistent thread form geometry on a wide range of workpiece materials. The 29-degree included angle matches the Acme thread standard, making it suitable for lead screw, power transmission, and motion-control threading applications. Machinists and toolroom technicians will find this insert compatible with standard 22U-style laydown toolholders in left-hand or right-hand configurations.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal Acme threading operations in job shops, production machining, and maintenance environments. The neutral hand designation allows use in both left-hand and right-hand toolholder setups without stocking separate inserts. The P30 carbide grade and bright uncoated finish make it effective across a broad spectrum of workpiece materials including steels, cast irons, non-ferrous metals, and superalloys. Typical applications include threading hydraulic cylinder bodies, lead screws, and power transmission components in both light and medium-duty cuts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide P30 grade for broad material compatibility across steel, cast iron, non-ferrous, and superalloy workpieces\u003c\/li\u003e\n\u003cli\u003e4 TPI Acme thread form with 29-degree included angle for accurate lead screw and power transmission profiles\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for applications where coating buildup or contamination is a concern\u003c\/li\u003e\n\u003cli\u003eNeutral hand insert style fits both left-hand and right-hand 22U laydown toolholders\u003c\/li\u003e\n\u003cli\u003e1\/2-inch inscribed circle and 0.187-inch thickness for use in standard 22U-series insert pockets\u003c\/li\u003e\n\u003cli\u003eMeets CE, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 22U-style laydown threading toolholders accepting a 1\/2-inch inscribed circle insert.
