Kennametal 1162009 TCMT2152LF KC730 Carbide Turning Insert

Product Description

The KENNAMETAL 1162009 is a solid carbide turning insert with ANSI designation TCMT2152LF and ISO designation TCMT110208, coated with titanium nitride (TiN) via a PVD process. It features the KC730 grade, engineered for high to moderate wear resistance with balanced toughness across steel, stainless steel, and cast iron workpiece materials. The insert uses a triangular shape with a 60-degree included angle, a positive rake of 5 degrees, and a 7-degree relief angle. The LF chip breaker geometry is optimized for finishing and light machining operations. Three cutting edges and a screw-on holding method make it a practical choice for production turning applications.

This insert is suited for finishing and light machining passes on steel, stainless steel, superalloys, and titanium in CNC turning, facing, and boring operations. The neutral hand orientation and positive side clearance make it adaptable across standard screw-on toolholders in both light production and job-shop environments. The honed cutting edge style reduces edge chipping during intermittent or entry-level cutting conditions. Machinists and CNC operators working with TCMT-style toolholders will find this insert a direct fit for precision turning setups requiring consistent surface finish.

Key Features

• KC730 PVD TiN-coated carbide grade with high wear resistance for steel and stainless steel applications
• LF chip breaker geometry designed for finishing and light machining operations
• Triangular insert shape with 60-degree included angle and 3 usable cutting edges
• Positive rake angle (5 degrees) and 7-degree relief angle for reduced cutting forces
• Honed cutting edge style for improved edge stability in finishing cuts
• Multi-use capability across turning, facing, and boring operations

Compatibility

Designed for use with standard TCMT-style screw-on toolholders accepting a 1/4-inch inscribed circle triangular insert. Conforms to ANSI and ISO standards for TCMT2152 and TCMT110208 insert sizes respectively.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator with the machine powered off and in a locked-out state before changing inserts. Use the appropriate Torx or hex key to seat the screw-on fastener securely without over-torquing the clamping screw. Verify that the toolholder pocket and seating surface are free of chips or debris before seating the insert. Follow the toolholder manufacturer guidelines and applicable shop safety procedures when indexing or replacing cutting edges.
