Seco 00072175 Turning Insert CNGP430-MF1 CP200 Carbide

Product Description

The SECO 00072175 is a solid carbide turning insert in the CNGP430-MF1 series, grade CP200, designed for precision metal cutting on CNC lathes and turning centers. The insert features a multilayer PVD coating of TiAlN and TiN, providing wear resistance and thermal stability at the cutting edge. It carries a 0.5-inch inscribed circle, a 0.1874-inch thickness, and a sharp cutting edge style with an MF1 chip breaker geometry suited for finishing and semi-finishing operations. With four usable cutting edges and a neutral hand orientation, this insert delivers consistent performance across medium-volume turning programs.

This insert is engineered primarily for machining stainless steel and superalloys including titanium, with secondary suitability for steel and cast iron workpieces. The MF1 chip breaker geometry is optimized for light to medium depth-of-cut finishing passes. It is applicable to boring, facing, and turning operations, making it a versatile option for job shops and production environments running difficult-to-machine materials. Licensed machinists and CNC operators typically specify this insert for ISO material groups M and S applications.

Compatibility

Designed for use in toolholders accepting CNGP-style inserts with a 0.5-inch inscribed circle and G tolerance, N clearance code. Compatible with clamp, pin, and lever lock holding systems. Suitable for boring, facing, and turning operations on stainless steel, superalloys, titanium, steel, and cast iron workpieces per ISO material codes M, S, P, and K.

Installation Notes

Installation is performed by qualified CNC machinists or tool room technicians. Ensure the machine spindle is fully stopped and the toolholder is secured before seating or indexing the insert. Confirm the insert pocket is clean and free of chips before clamping to maintain proper seating and edge geometry. Follow the toolholder manufacturer's clamping torque and securing method specifications for clamp, pin, or lever lock configurations.
