Kyocera TLE04421 Turning Insert CNMG432AH PDL025 Carbide

Product Description

The KYOCERA TLE04421 is a solid carbide turning insert with an Al2O3-based DLC coating, designed for high-performance machining of aluminum and non-ferrous metals. It carries the ANSI designation CNMG432AH and ISO designation CNMG120408AH, featuring an 80-degree diamond (rhombic) insert shape and a neutral hand orientation. With a 0.5 inch inscribed circle, a 0.0313 inch corner radius, and a negative rake angle of -9 degrees, this insert delivers high wear resistance across roughing and medium machining operations. It is installed by CNC machinists and tooling specialists in production turning environments.

This insert is suited for external turning, boring, facing, internal facing, and chamfering operations on non-ferrous workpiece materials including aluminum alloys. The AH chip breaker geometry is optimized for material grades N01, N10, and N20, supporting both roughing and medium-duty cuts. The DLC coating process enhances surface lubricity and wear resistance at the cutting edge, making it appropriate for high-speed aluminum machining where built-up edge is a concern. It seats in standard CNMG-style toolholders using clamp or pin holding methods.

Key Features

• ANSI code CNMG432 and ISO code CNMG120408 for broad toolholder compatibility
• DLC-coated solid carbide for high wear resistance on non-ferrous metals
• 80-degree diamond insert shape with negative rake and negative side clearance
• AH chip breaker geometry supports roughing and medium machining operations
• 4 cutting edges per insert; honed cutting edge style for consistent edge prep
• Multi-use application: external turning, boring, facing, internal facing, and chamfering

Compatibility

Designed for use in standard CNMG432-style toolholders accepting clamp or pin holding methods. Primary workpiece material is non-ferrous metal (material grades N01, N10, N20). Meets ANSI and ISO standards as noted in the insert designation CNMG432AHPDL025.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Ensure the machine spindle is fully stopped and the tool turret is indexed to a safe position before seating or replacing inserts. Use the correct clamp or pin-style toolholder specified for the CNMG432 insert size and verify proper seating before resuming cuts. Do not exceed the maximum depth of cut or the recommended feed range for the selected workpiece material grade.
