Manufactured from solid carbide and finished with a TiC\/TiN multilayer coating, this insert delivers wear resistance and thermal stability in threading operations on ferrous and non-ferrous materials. The right-hand configuration suits standard internal threading passes on CNC lathes and manual threading setups. With a 3\/8-inch inscribed circle and a 0.146-inch thickness, the H08704793 conforms to the 16IR insert style geometry, making it a direct fit for compatible 16IR toolholders. Machinists and tool-and-die professionals use this insert for precision thread forming in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal UN thread applications in both production machining and maintenance or repair threading work. The 24 TPI specification targets common UN fastener thread profiles used in general-purpose mechanical assemblies. The solid carbide substrate and TiC\/TiN finish support consistent thread geometry across multiple passes, making it appropriate for threading bores in steel, cast iron, and similar workpiece materials. A relief angle of 0 degrees is standard for laydown threading insert designs and provides maximum edge support during the cut.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with TiC\/TiN multilayer coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003e24 TPI UN internal thread profile, right-hand cut\u003c\/li\u003e\n  \u003cli\u003e16IR insert style with 3\/8-inch (0.375-inch) inscribed circle\u003c\/li\u003e\n  \u003cli\u003e0.146-inch insert thickness for secure laydown seating\u003c\/li\u003e\n  \u003cli\u003e0-degree relief angle provides maximum cutting edge support\u003c\/li\u003e\n  \u003cli\u003eHG330TR manufacturer grade suited for threading ferrous materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 16IR-style internal threading toolholders configured for UN thread forms.
