Kennametal 5388033 Turning Insert Ccmt 80 Diamond 3/8 in Ic

Product Description

The KENNAMETAL 5388033 is a CCMT-style indexable turning insert designed for general-purpose metal cutting on CNC lathes and manual turning centers. Manufactured from solid carbide with a multilayer MTCVD coating sequence of TiCN, Al2O3, and TiOCN under the KCP10B grade designation, this insert delivers thermal resistance and edge stability across moderate to high cutting speeds. The 80-degree diamond shape provides a strong cutting geometry, while the MF chip breaker and chamfered-and-honed cutting edge style make it well-suited for finishing and semi-finishing passes. Two usable cutting edges per insert and screw-on holding method keep tooling costs manageable in production environments. Licensed machinists, CNC operators, and tool-and-die professionals will find this insert straightforward to index and qualify.

The 5388033 is rated for primary workpiece materials of steel and cast iron, corresponding to ISO material codes P and K. Its positive rake geometry and MF chip breaker geometry work together to produce controlled chip evacuation during turning, facing, and boring operations. The insert measures 0.3808 inches in length with a 3/8-inch inscribed circle and a 1/32-inch corner radius, supporting a maximum depth of cut of 0.090 inches. It conforms to ANSI and ISO standards, with an ISO code of CCMT09T308MF and an industry standard number of CCMT3252MF, making cross-referencing to other tooling systems straightforward.

Key Features

• KCP10B carbide grade with multilayer CVD coating: TiCN, Al2O3, and TiOCN for thermal and wear resistance
• 80-degree diamond insert shape with neutral hand for flexible toolholder mounting
• MF chip breaker geometry optimized for finishing and semi-finishing cuts on steel and cast iron
• Screw-on holding method provides repeatable insert indexing and secure clamping
• Two cutting edges per insert; chamfered and honed edge prep reduces built-up edge tendency
• Positive rake angle supports lower cutting forces in medium-to-light depth-of-cut applications

Compatibility

Designed for use in CCMT-style screw-on toolholders accepting a 3/8-inch inscribed circle insert. Compatible with turning, facing, and boring operations on steel and cast iron workpiece materials per ISO P and K classifications. Conforms to ANSI and ISO insert standards; ISO designation CCMT09T308MF and industry standard CCMT3252MF apply.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Before indexing or replacing inserts, ensure the machine spindle is fully stopped and the toolholder is secured in the turret. Use the appropriate torque wrench per the toolholder manufacturer's clamping screw specification; do not use an impact driver on insert clamping screws. Inspect the insert pocket and seating surface for chips or debris before seating the new insert to ensure proper contact and accurate tool-nose radius positioning.
