This multi-tipped insert features a 35-degree diamond shape, a neutral hand orientation, and a flat-top chip breaker geometry. The cutting edges are chamfered and honed for consistent edge integrity. At 1.2598 inches in length with a 0.3750-inch inscribed circle and a 0.0157-inch corner radius, this insert is sized for moderate-depth finish and semi-finish turning passes. It is used by machining professionals on CNC lathes and turning centers in production environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning, facing, profiling, and back turning operations on hard materials and super-alloys including titanium. The PCBN substrate, grade CBN010, is engineered for interrupted and continuous cuts in hardened steels, cast irons, and superalloy components where carbide tooling reaches its limits. The uncoated bright finish allows direct visual inspection of edge condition. It is compatible with toolholders using clamp, pin, or lever lock holding methods, making it adaptable to a wide range of VNGA-style toolholder blocks already in common shop use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePCBN insert material (grade CBN010) rated for hard materials (H01, H10, H20) and super-alloys\u003c\/li\u003e\n  \u003cli\u003e35-degree diamond insert shape (Shape Code V) with neutral hand for flexible setup\u003c\/li\u003e\n  \u003cli\u003eChamfered and honed cutting edge style for controlled edge prep and consistent tool life\u003c\/li\u003e\n  \u003cli\u003eFlat-top chip breaker geometry; 2 cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp, pin, and lever lock toolholder holding methods\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; ISO equivalent code VNGA160404S-01020-L1-B\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in VNGA-series toolholders that accept clamp, pin, or lever lock insert retention.
