Kyocera TLE04420 Turning Insert CNMG431AH PDL025 Carbide

Product Description

The KYOCERA TLE04420 is a solid carbide turning insert in the CNMG431AH geometry with a PDL025 manufacturer grade. It features an Al2O3 DLC coating applied over carbide substrate, targeting non-ferrous metal workpieces including aluminum and other N-group materials. The insert carries an 80-degree diamond shape (Insert Shape Code C), a neutral hand orientation, and a honed cutting edge style with a negative rake angle of -9 degrees. A 1/2-inch inscribed circle and a 1/64-inch corner radius define the cutting geometry. This insert is intended for use by machinists and CNC turning specialists in production environments where tool life and surface finish consistency on non-ferrous materials are priorities.

This insert is suited for external turning, boring, internal facing, chamfering, and facing operations on non-ferrous metals classified under material grades N01, N10, and N20. It conforms to both ANSI and ISO standards, with the ISO designation CNMG120404AH. The ISOI series designation and CNMG insert style make it compatible with standard CNMG toolholders using clamp-and-pin holding methods. Typical applications include CNC lathes performing medium-duty passes on aluminum, copper, and similar non-ferrous workpiece materials.

Key Features

• Al2O3 DLC coating on carbide substrate optimized for non-ferrous metal cutting (N-group: N01, N10, N20)
• 80-degree diamond insert shape with honed cutting edge style for controlled chip formation
• Negative rake geometry (-9 degrees) with AH chip breaker designation
• 4 cutting edges per insert for extended tooling economy
• Compatible with clamp and pin holding methods in standard CNMG toolholders
• Rated for external turning, boring, internal facing, chamfering, and facing operations

Compatibility

Designed for use in standard CNMG-style toolholders accepting clamp and pin clamping. Conforms to ANSI and ISO standards (ISO code CNMG120404AH). Suitable for multi-use applications including boring, external turning, chamfering, facing, and internal facing on non-ferrous metal workpieces.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or replacing inserts. Verify the toolholder pocket is clean and free of debris before clamping the insert. Confirm clamp and pin engagement is secure before resuming cutting operations.
