Seco 02910963 Pcbn Turning Insert Vnga 35 Diamond

Product Description

The SECO 02910963 is a Polycrystalline Cubic Boron Nitride (PCBN) turning insert in the VNGA style, designed for precision machining of hard and difficult-to-cut materials. This uncoated, neutral-hand insert features a 35-degree diamond shape with a 3/8-inch inscribed circle and a 0.008-inch corner radius. It carries a flat-top chip breaker geometry and a chamfered and honed cutting edge. The manufacturer grade is CBN010, and the insert is multi-tipped with two cutting edges. Licensed machinists and CNC tooling specialists install and apply this insert in production turning operations.

This insert is suited for turning, facing, back turning, and profiling operations on hard materials and super-alloys including titanium. It conforms to both ANSI and ISO standards, with an ISO code of VNGA160402S-01020-L1-B and an industry standard number of VNGA330.5S-00420-L1-B. Typical applications include interrupted and continuous cuts on hardened steels and similar hard workpiece materials where CBN tooling is specified. The insert is held using clamp, pin, or lever lock methods.
