Built from solid carbide with a PVD-applied TiAlN coating, this right-hand insert is engineered for consistent thread form and extended tool life across a wide range of workpiece materials. It carries the PR1115 manufacturer grade designation and features a 60-degree included angle standard to UN thread profiles. The 9.53 mm inscribed circle and 3.68 mm thickness place it in the 16ER insert family. A licensed HVAC, plumbing, electrical, or machining professional using CNC turning centers or manual lathes will find this insert suited to precision threading applications requiring tight tolerances.\u003c\/p\u003e\u003cp\u003eThis insert is intended for external threading operations on CNC lathes and turning centers where UN-standard thread forms are required. The TiAlN finish provides thermal resistance and wear performance suitable for universal workpiece material classifications, including ferrous metals, non-ferrous metals, and engineering plastics. The 16ER series geometry and TF series designation make this a standard laydown format compatible with common external threading toolholders using ER-style insert pockets. Applications include production threading of fittings, fasteners, connectors, and precision mechanical components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with PVD TiAlN coating for extended wear life\u003c\/li\u003e\n\u003cli\u003e18 TPI, 60-degree included angle for UN external thread standard\u003c\/li\u003e\n\u003cli\u003ePR1115 grade designation optimized for universal workpiece materials\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting geometry for standard external threading operations\u003c\/li\u003e\n\u003cli\u003e9.53 mm inscribed circle with 3.68 mm insert thickness in the 16ER format\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.18 mm (0.0071 inches) for accurate thread root geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for external threading toolholders accepting 16ER-format laydown inserts with a 4.00 mm (0.1575 inch) mounting hole diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or tooling technicians on CNC or manual turning equipment. The machine spindle must be stopped and all motion arrested before seating or replacing the insert. Use the appropriate torx or clamp-screw driver to secure the insert to the specified clamping torque for the toolholder manufacturer. Inspect the insert pocket and clamping mechanism for wear or debris before seating a new insert to ensure proper contact and thread accuracy.\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: PR1115\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 Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: External\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 18 TPI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 9.53 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3.68 mm (0.1449 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.18 mm (0.0071 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 4.00 mm (0.1575 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KYOCERA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TJY18884\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KYOCERA","offers":[{"title":"Default Title","offer_id":51733398257970,"sku":"TJY18884","price":306.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/54392d2627d891396949a5f1d25e8af3_b5af3180-69b6-4ee9-9af4-fa5880576115.jpg?v=1788755158","url":"https:\/\/voomisupply.com\/products\/kyocera-tjy18884-threading-insert-18-tpi-un-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
