Sumitomo 19T6165 Turning Insert CNMG432EEX-AC5025S Carbide

Product Description

The SUMITOMO 19T6165 is a solid carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. It carries the ANSI designation CNMG432EEX with ISO code CNMG120408N-EX and is coated with TiAlSiN via a PVD process under SUMITOMO's proprietary Absotech Bronze designation. The insert features a neutral cutting hand, negative rake geometry at 16 degrees, and an EEX chip breaker configuration. At 0.5079 inches in length with a 0.5-inch inscribed circle and a 0.0313-inch corner radius, this insert is built for demanding stock removal and finishing applications on superalloy workpieces.

This insert is intended for machining superalloys, corresponding to material grade S20 and primary workpiece material code S. It is suited for use on CNC turning centers in both production shop and job shop environments where high-temperature alloys such as nickel-based or titanium-based superalloys are regularly machined. The AC5000S series is engineered for toughness and wear resistance in these difficult-to-cut materials. Installation is handled by machinists and CNC tooling technicians configuring tool holders for precision turning operations.

Key Features

• TiAlSiN PVD coating under the Absotech Bronze designation for heat and wear resistance in superalloy cutting
• EEX chip breaker geometry with negative rake at 16 degrees for controlled chip flow
• 80-degree diamond insert shape (shape code C) with 0.0313-inch corner radius
• Screw-holding method with clearance code N and tolerance code M for secure, repeatable seating
• Conforms to ANSI and ISO 13399 standards for broad tool holder compatibility
• AC5025S manufacturer grade targeting material grade S20 superalloy applications

Compatibility

Designed as an OEM-style replacement turning insert for CNMG-style screw-lock tool holders conforming to ANSI and ISO 13399 standards. Refer to your tool holder manufacturer's specifications to confirm insert seat geometry before installation.

Installation Notes

This insert is installed and indexed by qualified machinists or CNC tooling technicians. Power down and lock out the machine before changing inserts. Use the correct torx or hex key to the tool holder manufacturer's specified tightening procedure when securing the clamping screw. Inspect the insert seat and shim for wear or debris before seating a new insert to ensure proper contact and repeatability.
