Seco 02959918 CNMG542-M3 TP1501 Turning Insert Carbide

Product Description

The SECO 02959918 is a CNMG542-M3 indexable turning insert designed for steel, cast iron, and hard material machining in CNC lathe and turning center applications. Manufactured from solid carbide and coated via CVD with a multilayer Duratomic system — TiCN, Al2O3, and Cr — the insert delivers thermal stability and wear resistance across a range of cutting conditions. The TP1501 grade targets P10 and P20 steel classifications with secondary capability in cast iron (K) and hard materials (H). With four usable cutting edges and an M3 chip breaker geometry, it is suited for boring, facing, and general turning operations at moderate to aggressive material removal rates.

This insert is intended for use in production turning on CNC lathes and machining centers in both job shop and production environments. The 80-degree diamond (C) shape provides good nose strength for interrupted cuts and profiling. The M3 chip breaker geometry handles medium-depth roughing and semi-finishing passes on steel components. The chamfered and honed cutting edge style improves edge stability and reduces built-up edge when cutting ferrous workpieces. It is compatible with CNMG-style toolholders using clamp, pin, or lever-lock holding methods.

Key Features

• Duratomic CVD multilayer coating: TiCN, Al2O3, and Cr for thermal and wear resistance
• TP1501 grade optimized for P10 and P20 steel with K and H secondary capability
• M3 chip breaker geometry for medium roughing and semi-finishing
• Four cutting edges per insert for extended tool life economy
• Chamfered and honed cutting edge style reduces chipping and built-up edge
• Negative rake, neutral hand — compatible with clamp, pin, and lever-lock CNMG toolholders
• Multi-use application: boring, facing, and turning

Compatibility

Designed for use in CNMG-style toolholders with clamp, pin, or lever-lock holding methods. ISO code CNMG160608-M3; industry standard number CNMG542-M3. Conforms to ANSI and ISO insert standards. Primary workpiece material is steel (P); secondary materials include cast iron (K) and hard materials (H). Material grades P10 and P20.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and de-energize the machine tool, and ensure the spindle is fully stopped before indexing or replacing inserts. Use the appropriate torque wrench and manufacturer-specified clamping hardware for the toolholder type — do not over-torque the clamping screw. Inspect the insert seat and clamping surfaces for chips or debris before seating the new insert to ensure proper contact and cutting-edge positioning.
