Manufactured to ISO code LT11NR18UNCB and coated with TiAlN via a PVD process, this right-hand insert delivers wear resistance and heat stability across a range of demanding workpiece materials. It features a 1\/4 inch (6.35 mm) inscribed circle and a 3.04 mm thickness (0.1260 decimal inch). The KC5025 grade is engineered for threading operations on steel, stainless steel, cast iron, superalloys, and titanium. Installation is performed by qualified machinists in CNC turning or manual lathe applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal threading operations on a range of materials including steel, stainless steel, cast iron, superalloys, and titanium. The NR insert style and CB chipbreaker designation make it appropriate for controlled-chip threading on both production and job-shop turning equipment. It is configured for right-hand cutting direction and conforms to UN thread standards, making it a standard choice for unified national thread form generation in precision machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction in Kennametal KC5025 grade for extended tool life in difficult materials\u003c\/li\u003e\n  \u003cli\u003eTiAlN PVD coating for thermal resistance and reduced crater wear\u003c\/li\u003e\n  \u003cli\u003eRight-hand internal UN thread form at 18 TPI\u003c\/li\u003e\n  \u003cli\u003eNR insert style with CB chipbreaker for controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch inscribed circle (6.35 mm) with 3.04 mm insert thickness\u003c\/li\u003e\n  \u003cli\u003eCompatible with primary workpiece material codes P, M, K, and S per ISO classification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in toolholders accepting LT11-style laydown threading inserts with NR geometry.

Power down and lock out the lathe or turning center before seating or removing the insert. Use the appropriate torx or insert-clamping wrench specified by the toolholder manufacturer to secure the insert without over-torquing the clamp screw. Inspect the insert pocket for wear, chips, or debris before installing a new insert to ensure proper seating and thread accuracy.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: LT11NR18UNCB\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 Standard\u003c\/strong\u003e: UN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Internal\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\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: 1\/4 inch (6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3.04 mm (0.1260 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 3.25 mm (0.1280 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge to Theoretical Edge Length\u003c\/strong\u003e: 0.0240 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace of Insert to Tip Centerline\u003c\/strong\u003e: 0.0310 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1102 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 1712557\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744468336946,"sku":"1712557","price":302.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/94de1b503412e28e4c4c1b65e8472aa1.jpg?v=1788856932","url":"https:\/\/voomisupply.com\/products\/kennametal-1712557-threading-insert-18-tpi-1-4-in-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
