It carries a TiAlN finish applied via PVD coating, which increases surface hardness and heat resistance during threading operations. This is a left-hand insert sized for both internal and external thread applications. With a tip-to-top height of 0.1492 inches, a corner radius of 0.0410 inches, and a cutting tip width of 0.0409 inches, the geometry is optimized for consistent thread form on Acme profiles. Machinists and toolroom operators working on CNC lathes or manual turning centers will find this insert suited for precision threading work in C2 and C6 material grades.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in Acme thread applications, both internal and external, where a left-hand thread orientation is required. The Top Notch series is a common platform in production and job-shop turning environments. It is appropriate for threading ferrous and non-ferrous workpieces within the C2 and C6 material grade classifications. Typical install scenarios include threading lead screws, power screws, and similar Acme-profile components on lathes equipped with Top Notch-compatible toolholders. Insert size is 3, fitting the corresponding Top Notch holder pocket size.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide substrate with TiAlN PVD coating for improved wear resistance and heat tolerance\u003c\/li\u003e\n  \u003cli\u003eLeft-hand Acme thread profile at 8 TPI with 29-degree included angle\u003c\/li\u003e\n  \u003cli\u003eHandles both internal and external threading operations\u003c\/li\u003e\n  \u003cli\u003eInsert size 3 fits standard Top Notch series toolholders\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0410 inches for consistent thread root geometry\u003c\/li\u003e\n  \u003cli\u003eManufacturer grade KC5025 suitable for C2 and C6 material classifications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series toolholders accepting size 3 inserts.
