Built from solid carbide and finished with a TiAlN coating applied via PVD process, this insert is engineered for cutting right-hand external ISO threads at a 0.50mm pitch. The KC5025 grade designation indicates a carbide substrate optimized for threading operations in steel and stainless steel at demanding feed and speed conditions. The LT16ER style seat geometry keeps the insert low-profile in the pocket, reducing deflection and improving thread form accuracy. Machinists and CNC operators in precision machining and metalworking shops are the primary users of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external threading operations on turned components in industrial, automotive, aerospace, and general machining environments. It is used in applications requiring ISO-standard thread forms where consistent pitch accuracy and surface finish are required. The 3\/8 inch inscribed circle and CB chipbreaker designation make it appropriate for standard ER-style laydown insert pockets in compatible threading toolholders. It performs best in controlled CNC turning applications where coolant and rigid toolholding are available.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with TiAlN coating for wear and heat resistance in threading operations\u003c\/li\u003e\n\u003cli\u003ePVD coating process preserves sharp cutting edges critical for accurate thread form\u003c\/li\u003e\n\u003cli\u003eRight-hand external ISO thread geometry at 0.50mm pitch\u003c\/li\u003e\n\u003cli\u003eCB chipbreaker configuration for chip control during threading passes\u003c\/li\u003e\n\u003cli\u003e3\/8 inch (9.53mm) inscribed circle fits standard ER-style laydown toolholder pockets\u003c\/li\u003e\n\u003cli\u003eKC5025 grade carbide substrate designed for demanding threading conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement threading insert for use in compatible ER-style laydown threading toolholders accepting a 3\/8 inch inscribed circle insert with a 3.94mm hole diameter.

Always index or replace inserts with the machine powered down and the spindle locked. Use a proper torque wrench and insert screw driver to seat the insert fully in the pocket without overtightening. Follow the toolholder manufacturer guidelines for insert seating and screw torque to prevent pocket damage.\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: KC5025\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: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: 0.50mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: CB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (9.53mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3.44mm (0.1430 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 3.94mm (0.1551 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0101 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: 1690872\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740525789490,"sku":"1690872","price":617.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f2cd3d9f4fa3fdbdffac5e246675626.jpg?v=1788825676","url":"https:\/\/voomisupply.com\/products\/kennametal-1690872-threading-insert-iso-0-50mm-pitch-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
