Carrying the ANSI code 2NUCNGA433 and ISO code 2NU-CNGA120412, this insert features an 80-degree diamond shape, a negative rake angle, and an uncoated BN2000 grade substrate. With a 0.5 inch inscribed circle and a corner radius of 0.0469 inches (3\/64 inches), it delivers repeatable edge geometry for tight-tolerance turning operations. It is installed by machinists and tooling specialists working on CNC lathes and turning centers.\u003c\/p\u003e\u003cp\u003eThe 16JRCTT is engineered for turning hardened steel (workpiece material code H), making it well-suited for finish and semi-finish passes on hardened components such as bearing races, tooling components, and wear-resistant parts. The CNGA insert style is compatible with standard negative-rake turning toolholders using clamp and pin holding methods. The BN2000 grade is a general-purpose PCBN grade optimized for interrupted and continuous cuts on ferrous hardened materials, typically in the 45-65 HRC range. This insert ships individually with a minimum order quantity of one piece.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePCBN (Polycrystalline Cubic Boron Nitride) insert material for hardened steel turning\u003c\/li\u003e\n\u003cli\u003eBN2000 uncoated manufacturer grade for consistent edge performance\u003c\/li\u003e\n\u003cli\u003e80-degree diamond insert shape (shape code C) with negative rake geometry\u003c\/li\u003e\n\u003cli\u003e0.5 inch inscribed circle and 0.0469 inch corner radius for versatile depth-of-cut range\u003c\/li\u003e\n\u003cli\u003eClamp and pin holding method for secure seating in CNGA-style toolholders\u003c\/li\u003e\n\u003cli\u003e2 cutting edges per insert; chip breaker designation A\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO 13399 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNGA-style negative-rake turning toolholders that accept clamp and pin insert holding.
