Part of the Top Notch series, this NAS-style insert features a KC730 grade substrate with a Titanium Nitride (TiN) finish applied via PVD coating, which extends cutting edge life and reduces built-up edge on ferrous materials. It cuts Stub Acme thread forms at 6 TPI with a 29-degree included angle, and is configured for left-hand threading. The insert carries material grades C2, C3, and C4, making it suitable for a range of workpiece materials common in production turning environments. Machinists and CNC lathe operators are the primary installers of this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for both internal and external Stub Acme thread cutting on CNC and manual lathes. The Top Notch series is a common platform used in production shops handling threaded rod, lead screw, and power transmission component work where Stub Acme thread forms are specified. The left-hand configuration is important to confirm before ordering, as it is not interchangeable with right-hand toolholders. Insert size 3 must be matched to a compatible Top Notch series toolholder with the appropriate pocket geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC730 carbide grade with PVD Titanium Nitride (TiN) coating for extended tool life on ferrous materials\u003c\/li\u003e\n  \u003cli\u003eStub Acme thread form at 6 TPI with 29-degree included angle for accurate thread geometry\u003c\/li\u003e\n  \u003cli\u003eLeft-hand cut configuration for left-hand thread and toolholder setups\u003c\/li\u003e\n  \u003cli\u003eCuts both internal and external threads with a single insert style\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0650 inches for consistent thread root form\u003c\/li\u003e\n  \u003cli\u003eNAS insert style in the Top Notch series for secure, repeatable seating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Top Notch series toolholders accepting an NAS-style, size 3 insert with a left-hand configuration.
