It is manufactured from carbide with a PVD-applied AlTiN finish, which provides heat resistance and extended tool life in ferrous and hard-to-machine materials. The insert carries the KCU10 manufacturer grade designation and features an NTC3R8E style profile with a 60-degree included angle and a corner radius of 0.0161 inches (0.41 mm). Thickness is 0.195 inches (4.95 mm). It is installed and indexed by machinists and CNC operators working on turning centers, manual lathes, and OD threading applications in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external UN thread production at 8 TPI in applications ranging from fastener manufacturing to precision component threading. The AlTiN coating supports dry or minimal-coolant cutting strategies at elevated speeds. The Top Notch system uses a secure insert-clamping design that allows repeatable indexing without full tool disassembly, making it a common choice on production lathes where cycle time and insert changeover speed matter. Insert size is 3, consistent with the Top Notch toolholder family for that size range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide substrate with PVD AlTiN finish for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003e8 TPI external thread form, UN standard, 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation\u003c\/li\u003e\n  \u003cli\u003eCorner radius 0.0161 inches (0.41 mm) for accurate thread root geometry\u003c\/li\u003e\n  \u003cli\u003eTop Notch series insert style NTC3R8E for secure, repeatable indexing\u003c\/li\u003e\n  \u003cli\u003eKCU10 grade suited for a range of ferrous and wear-resistant workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KENNAMETAL Top Notch series toolholders accepting size 3 inserts in external threading configurations.

Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench or clamp key specified for the toolholder to secure the insert without cracking the carbide. Inspect the insert seat and clamp for debris before seating a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NTC3R8E\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: AlTiN\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\u003eExternal Pitch\u003c\/strong\u003e: 8 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0161 inches (0.41 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.195 inches (4.95 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 9.3 x 3.8 x 1.2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.031 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291804\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: 4176207\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51755079074098,"sku":"4176207","price":245.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c14980cfa4bf1fc60fd5688257a7b52a_83789566-d85c-452d-a3b3-aa9d7b978201.jpg?v=1788950919","url":"https:\/\/voomisupply.com\/products\/kennametal-4176207-threading-insert-8-tpi-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
