Description

The SECO 02649599 is a polycrystalline cubic boron nitride (PCBN) turning insert in the CCGW series, designed for high-hardness and abrasive machining applications on CNC lathes and turning centers. It carries a CCGW style profile with an 80-degree diamond shape, a 1/4-inch inscribed circle, and a 1/64-inch corner radius. The insert is uncoated, neutral-hand, and features a flat-top chip breaker geometry with a honed cutting edge. With two available cutting edges per insert, it delivers reliable performance in production turning environments. This insert is installed and indexed by machinists and tooling technicians working with precision turning toolholders.

The 02649599 is engineered for turning, facing, and boring operations on difficult-to-machine workpiece materials. Its primary application is machining cast iron, and it is also suited for super-alloys, titanium, and hard materials. The flat-top geometry and positive rake angle make it well-suited for finishing and semi-finishing passes where dimensional accuracy and surface finish are priorities. It fits standard CCGW-compatible toolholders using screw-type insert holding and is appropriate for both production shop and job shop environments handling hardened or abrasive materials.

80-degree diamond insert shape (CCGW style) with flat-top chip breaker geometry
Neutral hand orientation compatible with standard CCGW screw-type toolholders
Honed cutting edge style for improved edge stability during finishing operations
Two cutting edges per insert for extended tool life and cost efficiency
Suitable for turning, facing, and boring in multi-use applications

Compatibility

Designed for use in CCGW-series screw-clamp turning toolholders. ISO code CCGW060204E-L1-B and industry standard number CCGW21.51E-L1-B apply. Conforms to ANSI and ISO insert standards. Verify toolholder pocket geometry and insert seat dimensions before installation.

Installation Notes

This insert is indexed and installed by qualified machinists or tooling technicians on CNC or manual turning equipment. Power down and lock out the machine spindle before changing or indexing inserts. Use the appropriate torque wrench and insert screw specified by the toolholder manufacturer do not overtighten the clamping screw, as this can fracture the PCBN tip. Inspect the insert pocket and seating surface for chips or debris before seating a new insert.
