Kennametal 1160932 Turning Insert TNGP331 KC730 Carbide

Product Description

The KENNAMETAL 1160932 is a solid carbide turning insert with ANSI code TNGP331 and ISO code TNGP160404, designed for external and internal turning operations in metal cutting applications. Manufactured to the KENLOC series standard, this insert features a 60-degree triangular shape with a negative rake angle and zero-degree relief angle, providing six usable cutting edges per insert. The KC730 grade carries a PVD-applied TiN coating engineered for high wear resistance with maintained toughness across steel, stainless steel, and cast iron workpiece materials. The insert measures 0.6496 decimal inches in length with a 3/8-inch inscribed circle and a 1/64-inch corner radius, and is held in place by clamp or pin toolholders.

This insert is suited for turning, facing, and boring operations in medium machining conditions. Primary workpiece materials include steel (P), stainless steel (M), superalloys, and titanium, with secondary compatibility across M and S material codes. The neutral hand orientation makes it adaptable across standard KENLOC-compatible toolholders. Typical environments include CNC turning centers and manual lathes in production and job shop settings. Installation and toolholder selection are performed by machinists and tooling technicians working to ANSI and ISO insert standards.

Key Features

• KC730 grade with PVD TiN coating for high wear resistance on steel and stainless steel
• 60-degree triangle insert shape with six usable cutting edges for extended tool life
• Negative rake and zero-degree relief angle for rigid, stable cutting performance
• Honed cutting edge style reduces micro-chipping on interrupted and continuous cuts
• Maximum depth of cut of 0.0492 inches (1.25 mm) for medium machining applications
• Meets ANSI and ISO dimensional standards for broad toolholder compatibility

Compatibility

Designed for use with KENLOC-series toolholders accepting TNGP-style inserts with clamp or pin holding methods. Compatible with ANSI size code 331 and ISO size code 160404 toolholder seats. Suitable for steel (P), stainless steel (M), cast iron (K), superalloys, and titanium workpiece materials per the KC730 grade specification.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or removing inserts. Ensure the toolholder pocket and seating surface are clean and free of chips before inserting. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer — do not overtighten the clamp screw, as this can fracture the carbide substrate.
