It carries the KC850 manufacturer grade and features a CVD-applied TiC\/TiCN\/TiN multilayer coating that promotes wear resistance and thermal stability during continuous threading cuts. The insert follows a partial profile 60-degree thread standard and is suited for cutting threads in the 1.25 mm to 6.25 mm pitch range, covering 4 to 20 TPI. Right-hand cutting geometry and a 0.11 mm corner radius (approximately 0.0043 inch) define the cutting edge profile. This insert is part of the Kennametal Top Notch series and is installed by machinists and CNC turning specialists in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThe 1183781 fits external threading applications on CNC lathes and manual turning centers where the Top Notch toolholder system is in use. Its 60-degree included angle makes it appropriate for Unified National (UN) and metric partial-profile thread forms. Typical applications include threading steel, stainless steel, and similar materials where CVD-coated carbide provides adequate tool life. This insert is sold individually per package with a minimum order quantity of 5 pieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC850 grade carbide with CVD TiC\/TiCN\/TiN multilayer coating for wear resistance\u003c\/li\u003e\n\u003cli\u003ePartial profile 60-degree thread standard for external UN and metric thread forms\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation\u003c\/li\u003e\n\u003cli\u003e0.11 mm (0.0043 inch) corner radius\u003c\/li\u003e\n\u003cli\u003eCovers 1.25 mm to 6.25 mm pitch range (4 to 20 TPI)\u003c\/li\u003e\n\u003cli\u003ePart of the Top Notch series toolholder system\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Kennametal Top Notch series threading toolholders configured for external right-hand threading operations with a 60-degree insert seat.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians.
