Manufactured from solid carbide with a PVD-applied AlTiN finish, it delivers heat resistance and edge retention under demanding threading conditions. The insert carries a 60-degree included angle and a 0.0062-inch corner radius, conforming to standard UN thread form geometry. Insert size is 3, with a thickness of 0.195 inches (4.95 mm). Machinist and toolroom technicians install this insert into compatible Top Notch threading toolholders for high-production external threading on lathes and turning centers.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for external threading operations on CNC lathes and manual turning equipment wherever a 20 TPI UN thread form is required. The KCU10 grade with AlTiN coating performs well in steel and alloy applications at moderate-to-high cutting speeds. Right-hand cutting orientation makes it the standard choice for conventional external threading passes. It is sold individually per package, with a minimum order quantity of 5 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide substrate with PVD AlTiN finish for elevated wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003e20 TPI external UN thread profile with 60-degree included angle\u003c\/li\u003e\n  \u003cli\u003eKCU10 manufacturer grade optimized for threading in steel and alloy materials\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0062 inches (0.16 mm) for accurate thread root form\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting orientation for standard external threading passes\u003c\/li\u003e\n  \u003cli\u003eTop Notch series insert size 3, thickness 0.195 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in KENNAMETAL Top Notch series threading toolholders that accept size 3 NTC inserts.
