Kyocera TMH00069 Turning Insert WNMG432 Carbide

Product Description

The KYOCERA TMH00069 is a solid carbide turning insert with a WNMG432 ANSI designation and ISO code WNMG080402, engineered for steel cutting applications requiring a balance of wear resistance and toughness. It carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN - grade CA025P - which places it in material grades P10 through P40. The insert has an 80-degree trigon shape, a neutral hand orientation, a 0.5 inch inscribed circle, and a corner radius of 0.0313 inches. With six cutting edges and a chamfered, honed cutting edge style, it delivers consistent performance across roughing and medium machining operations.

This insert is suited for external turning, boring, facing, internal facing, and chamfering on steel workpieces in both production and job-shop environments. The PG chip breaker geometry supports chip control through a range of depths of cut up to a maximum of 0.059 inches. It is mounted using either a clamp or pin holding method, making it compatible with standard WNMG-style toolholders used by machinists and CNC operators in metal-cutting applications. The negative rake angle of -15 degrees and negative side clearance are consistent with the WNMG insert family geometry.

Key Features

• CVD multilayer coating: TiCN, Al2O3, TiN for high wear resistance on steel
• Grade CA025P rated for P10, P20, P30, and P40 steel material grades
• Six cutting edges for extended tooling economy
• PG chip breaker supports roughing and medium machining operations
• Chamfered and honed cutting edge style for edge stability
• Dual holding method compatibility: clamp or pin

Compatibility

Designed for use in standard WNMG432-compatible toolholders conforming to ANSI and ISO insert standards. Suitable for external turning, boring, facing, internal facing, and chamfering operations on steel workpieces.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine spindle before seating or indexing inserts. Ensure the insert pocket and seating surface are clean and free of chips before clamping. Use the appropriate torque for the clamping screw per the toolholder manufacturer specification - do not overtighten, as this can fracture the insert body.
