It carries the LT16NRA60 insert style designation and is manufactured in grade KC5010 with a PVD-applied TiAlN coating. The insert produces a partial profile 60-degree thread form and covers a thread range of 48 to 16 TPI, corresponding to a pitch range of 0.50 to 1.50 mm. With a 3\/8 inch (9.53 mm) inscribed circle and a thickness of 0.1430 inches (3.44 mm), it seats in standard 16NR-style laydown threading toolholders. Licensed machinists and CNC lathe operators use this insert for precision internal threading in ferrous and non-ferrous materials.\u003c\/p\u003e\u003cp\u003eThis insert is suited for internal threading on CNC lathes and turning centers in production and job-shop environments. The KC5010 grade is a PVD-coated carbide substrate intended for threading at controlled cutting parameters. The partial profile 60-degree geometry makes it compatible with Unified (UN), metric, and other 60-degree thread standards where the insert tip generates the thread form without requiring an exact TPI match to the programmed pitch. It is commonly used in both light and moderate production runs where consistent thread quality and insert life are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate in manufacturer grade KC5010 for wear resistance in threading applications\u003c\/li\u003e\n\u003cli\u003ePVD TiAlN coating reduces heat buildup and extends tool life at the cutting edge\u003c\/li\u003e\n\u003cli\u003ePartial profile 60-degree thread form covers 48-16 TPI (0.50-1.50 mm pitch) with a single insert\u003c\/li\u003e\n\u003cli\u003eRight-hand internal threading geometry for standard CNC lathe boring bar and threading toolholder setups\u003c\/li\u003e\n\u003cli\u003e3\/8 inch (9.53 mm) inscribed circle in the LT16NR laydown insert style for broad toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0020 inches (0.05 mm) for accurate thread root profile\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for standard LT16NR-style laydown threading toolholders accepting a 3\/8 inch inscribed circle insert with a 0.1551 inch (3.94 mm) hole diameter.

Power down and de-energize the machine tool, and engage the spindle lock before seating or removing the insert. Use the correct torx or hex key specified for the toolholder clamping screw  -  do not overtighten, as carbide inserts are brittle and can fracture under excessive clamp force. Verify insert seating and edge condition before returning the machine to cycle.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: LT16NRA60 (16NR Laydown)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5010\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\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: Internal Partial Profile 60 Degree\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 (TPI)\u003c\/strong\u003e: 48-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch Range\u003c\/strong\u003e: 0.50-1.50 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\u003eCorner Radius\u003c\/strong\u003e: 0.0020 inches (0.05 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: 0.0101 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: 1724415\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743993725234,"sku":"1724415","price":617.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4a21a006c0e1743894a20a1006fc509a.jpg?v=1788852553","url":"https:\/\/voomisupply.com\/products\/kennametal-1724415-threading-insert-60-degree-3-8-ic-48-16-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
