Sumitomo 19T2200 Carbide Turning Insert DNMG432ENZ AC4015K

Product Description

The SUMITOMO 19T2200 is a solid carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. Manufactured to ANSI code DNMG432ENZ and ISO code DNMG150408N-UZ, this insert features a CVD-applied Al2O3/TiCN multilayer coating under the proprietary Super FF designation, grade AC4015K. The 55-degree diamond shape with a neutral cutting direction suits a wide range of turning profiles. With a 1/2-inch inscribed circle, a 3/16-inch insert thickness, and a 1/32-inch corner radius, the insert is built for consistent performance on cast iron workpieces. Pin and screw holding method ensures rigid, repeatable seating in compatible toolholders.

This insert is engineered primarily for turning cast iron (material grade K15, workpiece material code K) in both roughing and semi-finishing applications. The ENZ chip breaker geometry and negative rake angle of 4 degrees promote controlled chip flow and stable cutting forces on ferrous materials. It is suited for use in production turning environments where surface finish consistency and insert life on cast iron components are priorities. Licensed machinists and CNC operators in manufacturing and job shop settings are the primary installers and end users.

Key Features

• CVD-coated Al2O3/TiCN multilayer finish under Sumitomo Super FF designation for wear resistance on cast iron
• DNMG insert style with 55-degree diamond shape and negative rake for stable, rigid cutting
• ENZ chip breaker geometry optimized for controlled chip evacuation on ferrous workpieces
• Neutral cutting direction for flexible right-hand or left-hand toolholder compatibility
• Pin and screw holding method for secure, repeatable insert indexing
• Compliant with ANSI and ISO 13399 standards for toolholder interface data

Compatibility

Designed as an OEM-style replacement or direct-use insert for DNMG-style toolholders accepting a 1/2-inch inscribed circle insert with pin and screw clamping. Verify toolholder pocket geometry and clamping style before installation.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque screwdriver or pin clamp tool specified by the toolholder manufacturer to seat the insert without cracking the carbide substrate. Never apply side force to unseat a carbide insert — use the proper ejection tool to avoid chipping the cutting edge or damaging the pocket.
