Seco 02730814 Cnmg 432-MF5 TH1000 Carbide Turning Insert

Product Description

The SECO 02730814 is a CNMG 432-MF5 series indexable turning insert designed for precision material removal in demanding machining applications. Manufactured from solid carbide with a multilayer TiAlSiN PVD coating and TH1000 grade designation, this insert delivers wear resistance and thermal stability at the cutting zone. It features an 80-degree diamond insert shape, a 0.5000-inch inscribed circle, and a 1/32-inch (0.0315-inch) corner radius. The MF5 chip breaker geometry paired with a chamfered and honed cutting edge style targets consistent chip control. Four cutting edges are available per insert, reducing tooling cost per edge. Licensed machinists and CNC tooling specialists install and index this insert in production turning, boring, and facing operations.

This insert is suited for machining superalloys, titanium, and hard materials — workpiece material codes S and H — where edge toughness and coating adhesion are critical. Material grades S05 and H05 indicate suitability for light to medium cutting parameters in these material families. The MF5 geometry supports finishing and semi-finishing passes. The neutral hand orientation allows use in both left- and right-hand toolholders depending on the application setup. Compatible multi-use applications include turning, facing, and boring in CNC lathe and turning center environments.

Key Features

• TiAlSiN multilayer PVD coating with TH1000 grade for superalloy and hard material cutting
• MF5 chip breaker geometry with chamfered and honed cutting edge for controlled chip formation
• Four usable cutting edges per insert for extended tooling economy
• 80-degree diamond insert shape (C code) with negative rake and 0-degree relief angle
• Neutral hand orientation compatible with clamp, pin, and lever lock insert holding methods
• Meets ANSI and ISO standards; ISO code CNMG120408-MF5, industry standard CNMG432-MF5

Compatibility

Designed for use in CNMG-style toolholders accepting a 432 insert size with clamp, pin, or lever lock holding methods. Confirmed for turning, facing, and boring operations on superalloys, titanium, and hard materials (material codes S and H). Verify toolholder clearance and clamping style before installation.

Installation Notes

Indexable insert installation and indexing should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before removing or indexing any insert. Use the correct torque wrench and manufacturer-specified fastener for the toolholder clamping system — clamp, pin, or lever lock as applicable — to ensure proper seating without cracking the carbide. Inspect the insert pocket and seating surface for chips or debris before installing a fresh cutting edge.
