Kyocera TMK00414 TPMT222 Carbide Turning Insert

Product Description

The KYOCERA TMK00414 is a TPMT-style triangular carbide turning insert designed for precision metal cutting in CNC and manual lathe applications. Manufactured in the CA125P grade with a CVD-applied TiCN/Al2O3/TiN multilayer coating, this insert delivers wear resistance and thermal stability across a range of turning operations. It carries an 11-degree relief angle (clearance code P), a positive rake geometry, and an HQ chip breaker configuration. With three usable cutting edges per insert and neutral hand orientation, it suits a broad range of single-point turning setups. Licensed machinists and CNC operators working in production environments are the primary users.

This insert is suited for external turning, internal facing, boring, back boring, and copying operations. Primary workpiece materials are carbon steel and alloy steel (ISO material group P). The TPMT110308 ISO designation and 222 ANSI insert size code make it straightforward to cross-reference against toolholder specifications. Its screw-and-clamp holding method is compatible with standard TPMT-pocket toolholders used across both light and moderate-duty turning applications in job shop and production environments.

Key Features

• CA125P carbide grade with CVD TiCN/Al2O3/TiN multilayer coating for wear and heat resistance
• HQ chip breaker geometry optimized for carbon steel and alloy steel (ISO P workpiece group)
• Three cutting edges per insert for extended tool life per unit
• 11-degree positive relief angle reduces cutting forces on light to moderate cuts
• Compatible with screw and clamp toolholder retention systems
• Multi-use geometry supports external turning, boring, back boring, internal facing, and copying

Compatibility

Designed for use in TPMT-pocket toolholders accepting a 222 ANSI insert size (inscribed circle 0.2500 inches, thickness 0.1252 inches). Verify toolholder pocket geometry and insert retention method before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before seating or changing inserts. Use the correct torque driver or clamp screw specified by the toolholder manufacturer — do not overtighten, as this can fracture the carbide substrate. Inspect the pocket seating surface for chips or debris before installing a fresh insert.
