Manufactured to the LT16ER125ISOCB geometry, it carries the KC5010 grade designation and features a TiAlN coating applied via PVD process. The insert produces right-hand external ISO threads at a 1.25 mm pitch and suits high-precision threading passes in production and job-shop environments. With a 3\/8 inch (9.53 mm) inscribed circle and a thickness of 0.1430 inches (3.44 mm), it fits standard 16-style laydown toolholders. Machinists and CNC operators handling steel, stainless, and similar materials in volume threading applications install this insert.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external threading on workpieces requiring ISO metric thread profiles at 1.25 mm pitch. It is intended for use on CNC turning equipment in both residential-shop and industrial production settings where consistent thread form and tool life are priorities. The CB chipbreaker geometry assists in chip control during threading passes. The PVD TiAlN coating provides thermal resistance and wear protection, making this insert appropriate for dry or minimally lubricated threading cycles on ferrous and hard materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC5010 grade solid carbide construction with PVD-applied TiAlN coating for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand external ISO thread geometry at 1.25 mm pitch\u003c\/li\u003e\n\u003cli\u003eLT16ER form factor fits standard 16-style laydown threading toolholders\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 3.94 mm hole diameter for secure toolholder seating\u003c\/li\u003e\n\u003cli\u003eConsistent thread form suited to production threading of ISO metric fastener profiles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 16-style laydown threading toolholders that accept external ISO threading inserts with a 3\/8 inch inscribed circle and 0.1551 inch hole diameter.

Power down and lock out the machine before changing inserts. Use the appropriate torx or insert-clamping wrench specified by the toolholder manufacturer to seat the insert securely  -  do not overtighten by hand estimation alone. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert, and confirm thread pitch programming in the CNC control matches the 1.25 mm pitch of this insert before initiating a threading cycle.\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\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Pitch\u003c\/strong\u003e: 1.25 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: CB\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\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\u003eWeight\u003c\/strong\u003e: 0.011 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: 1690877\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51739843363122,"sku":"1690877","price":74.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2c7299052f5c7bb283c1f44554fcfc7a.jpg?v=1788819509","url":"https:\/\/voomisupply.com\/products\/kennametal-1690877-threading-insert-iso-external-rh-tialn","provider":"Voomi Supply","version":"1.0","type":"link"}
