Kennametal 5652776 Turning Insert DNMG331A3J SP4019 Carbide

Product Description

The KENNAMETAL 5652776 is a DNMG-style solid carbide turning insert with grade SP4019 and a 3J chip breaker geometry, designed for precision turning operations on CNC lathes and similar machine tools. The insert features a 55-degree diamond (rhombic) shape with a negative side clearance and a corner radius of 1/64 inch (0.0156 inch). It is held in place using a clamp and pin method, providing secure seating during interrupted and continuous cuts. Machinists and tooling technicians working in production turning environments install and index this insert as part of a standard toolholder system.

This insert is suited for external and internal turning applications where a DNMG form factor is specified. The SP4019 carbide grade and 3J chip breaker make it appropriate for a range of ferrous and non-ferrous workpiece materials in medium to finish turning passes. It is packaged individually but sold in multiples of 10, which aligns with shop-floor tooling replenishment workflows. The ANSI insert code is DNMG331 and the ISO insert code is DNMG110404.

Key Features

• 55-degree diamond (rhombic) insert shape for versatile turning access angles
• SP4019 carbide grade with 3J chip breaker geometry for controlled chip evacuation
• Corner radius of 1/64 inch (0.0156 inch) for finish-oriented turning passes
• Negative side clearance (clearance code N, tolerance code M) for rigid, stable cutting
• Clamp and pin holding method for positive insert location in compatible toolholders
• ANSI size code 331; ISO size code 110404; UNSPSC 23242105

Compatibility

Designed for use in DNMG-style toolholders that accept a 331 ANSI size insert with clamp and pin retention. Specific toolholder compatibility should be verified against the ANSI insert code DNMG331 and ISO code DNMG110404 using the machine tool manufacturer or toolholder supplier specifications.

Installation Notes

This insert is installed and indexed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Ensure the toolholder pocket and seating surfaces are clean and free of chips before seating the insert. Do not exceed the toolholder or insert manufacturer recommended cutting parameters for depth of cut, feed rate, or surface speed.
