Kyocera TLK04420 Turning Insert CNMG431AH PDL010 Carbide

Product Description

The KYOCERA TLK04420 is a CNMG-style carbide turning insert with a Diamond-Like Carbon (DLC) coating, designed for precision metal removal on non-ferrous workpiece materials. It features an 80-degree diamond insert shape, a 1/2-inch inscribed circle, and a 1/64-inch corner radius with a honed cutting edge style. The negative rake geometry and CNMG431AH chip breaker configuration support stable cutting action across a range of turning operations. This insert is handled by machinists and CNC operators working on lathes and turning centers in production and job-shop environments.

The TLK04420 is suited for external turning, internal facing, boring, chamfering, and facing operations on non-ferrous metals. The DLC coating process delivers a hard, low-friction surface that performs well on aluminum, copper alloys, and similar materials. With four available cutting edges per insert and a multi-use design, it supports efficient tooling utilization across a variety of setups. The ISO code for this insert is CNMG120404AH, and the industry standard number is CNMG431AHPDL010.

Key Features

• Diamond-Like Carbon (DLC) coating for low-friction performance on non-ferrous metals
• 80-degree diamond insert shape (Shape Code C) with negative rake angle of -9 degrees
• Four cutting edges per insert for extended tooling value
• Honed cutting edge style for consistent edge integrity
• Compatible with clamp and pin insert holding methods
• Meets ANSI and ISO standards; ISO code CNMG120404AH

Compatibility

Designed as a CNMG431AH-style replacement insert for CNC turning centers and lathes configured for CNMG-series toolholders using clamp or pin retention. Material grades N01, N10, and N20 indicate suitability for non-ferrous metal applications. Confirm toolholder seat geometry and pocket dimensions before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and locked out before changing inserts. Seat the insert firmly against the toolholder pocket and tighten the clamp or pin per the toolholder manufacturer's torque procedure. Inspect the cutting edge and chip breaker for seating alignment before resuming cuts.
