Description

The SECO 02743123 is a solid carbide cutoff and parting insert designed for precision grooving and parting operations on CNC lathes and turning centers. Manufactured to CP500 grade with a micrograin carbide substrate, it carries a PVD-applied TiAlN/TiN dual-layer coating that extends tool life across a broad range of workpiece materials. The insert features a 3.1mm cutting width, a 6-degree neutral lead angle, and an 0.008 inch corner radius, making it suitable for demanding parting applications where dimensional consistency and surface finish are critical. It is a single-end insert held in place by a clamp-style toolholder.

The 02743123 is intended for parting and cutoff operations in general-purpose turning applications. The universal primary workpiece material designation means it is engineered to perform across steel, stainless, cast iron, aluminum, and similar materials without requiring a workpiece-specific grade. It belongs to the SECO Series 150.10 insert family, fitting toolholders designed for that insert seat size 3 system. Typical users are CNC machinists and tool-and-die professionals working in production turning environments.

Key Features

CP500 micrograin solid carbide grade for wear resistance and edge stability
PVD TiAlN/TiN dual-layer coating applied for extended tool life and heat resistance
3.1mm cutting width with a 6-degree neutral lead angle for balanced cutting forces
0.008 inch corner radius for controlled chip formation and surface finish
Clamp-style insert holding method for rigid, repeatable seating
Universal workpiece material compatibility across ferrous and non-ferrous applications

Compatibility

Designed for use with Series 150.10 clamp-style parting and cutoff toolholders accepting insert seat size 3. Specific toolholder compatibility should be confirmed against the SECO Series 150.10 toolholder catalog prior to ordering.

Installation Notes

Installation and insert changes should be performed by a qualified machinist with the machine in a full stop, locked-out condition per applicable LOTO procedures. Use the correct SECO clamp key or torx driver specified for the Series 150.10 toolholder to seat the insert without over-torquing the clamp screw. Inspect the insert pocket and clamp for chips or debris before seating a new insert. Do not use damaged or chipped inserts, as insert failure at cutting speed presents a serious safety hazard.
