Manufactured to the KC5010 grade with a PVD-applied TiAlN coating, it delivers wear resistance and thermal stability across a broad range of threading applications. The insert cuts a partial profile 60-degree thread form and covers a pitch range of 0.50 to 3.00 mm (48 to 8 TPI), making it versatile across common metric and unified thread standards. It carries a 3\/8-inch (9.53 mm) inscribed circle and measures 0.1430 inches (3.44 mm) thick. This insert is installed by machinists and CNC tooling technicians in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external threading operations on ferrous and non-ferrous materials in both production and maintenance machining settings. The CB chipbreaker geometry is designed to control chip flow during threading passes, reducing the risk of chip entanglement on the workpiece or toolholder. Typical applications include threading steel, stainless, and similar machinable alloys on manual or CNC turning equipment. The partial profile 60-degree form allows the same insert to cut both unified and metric 60-degree thread families within its pitch range.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC5010 carbide grade with PVD TiAlN coating for extended tool life in threading applications\u003c\/li\u003e\n\u003cli\u003ePartial profile 60-degree thread form covers 0.50 to 3.00 mm pitch (48-8 TPI)\u003c\/li\u003e\n\u003cli\u003eRight-hand cut geometry for standard external threading setups\u003c\/li\u003e\n\u003cli\u003eCB chipbreaker for controlled chip evacuation during threading passes\u003c\/li\u003e\n\u003cli\u003e3\/8-inch inscribed circle with 0.1551-inch hole diameter for secure toolholder seating\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0031 inches (0.08 mm) for precise thread root geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use threading insert for toolholders accepting a 16ER-style laydown insert with a 3\/8-inch inscribed circle and 0.1551-inch hole diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing the insert. Use the appropriate torx or clamp screw driver to secure the insert to the specified toolholder clamp torque listed in the toolholder manufacturer documentation. Inspect the toolholder pocket for chips or debris before seating the insert to ensure proper contact and prevent premature edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 16ER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5010\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Right Hand External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Partial Profile 60 Degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 48-8 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch Range\u003c\/strong\u003e: 0.50-3.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1430 inches (3.44 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1551 inches (3.94 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0031 inches (0.08 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: CB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0088 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1679779\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743974129970,"sku":"1679779","price":533.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d27570401088e7b4fe3dfac255d124be.jpg?v=1788852216","url":"https:\/\/voomisupply.com\/products\/kennametal-1679779-threading-insert-60-degree-3-8-inch-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
