Seco 00064903 Turning Insert Cpmt 21.51-F1 CP200 Carbide

Product Description

The SECO 00064903 is a solid carbide turning insert in the CPMT-F1 series, designed for precision metal cutting in CNC turning centers and manual lathes. It carries a multilayer TiAlN and TiN coating applied via PVD process, which provides heat resistance and extended edge life in demanding cuts. The insert features an 80-degree diamond shape, a 0.25-inch inscribed circle, and a 1/64-inch corner radius. The F1 chip breaker geometry and sharp cutting edge style suit finishing and semi-finishing passes. Neutral hand orientation and a positive rake angle make it adaptable across common turning toolholders.

This insert is engineered primarily for machining stainless steel, superalloys, and titanium, with secondary capability on steel and cast iron. It is suited for boring, facing, and turning operations in production and job-shop environments. Typical users include CNC machinists and toolroom operators working to tight tolerances on aerospace, medical, or industrial components. The screw-holding method provides secure clamping in compatible CPMT-style toolholders. With two cutting edges per insert, it delivers consistent performance and cost efficiency per part.

Key Features

• Solid carbide substrate with multilayer TiAlN and TiN PVD coating for heat and wear resistance
• 80-degree diamond insert shape (Shape Code C) with positive rake for reduced cutting forces
• F1 chip breaker geometry optimized for finishing and semi-finishing passes
• 1/64-inch corner radius and sharp cutting edge for precise surface finishes
• Two usable cutting edges per insert for extended tooling value
• Compatible with boring, facing, and turning applications on a single insert

Compatibility

Designed for use in CPMT-style screw-on toolholders conforming to ANSI and ISO standards. ISO code CPMT060204-F1; industry standard number CPMT21.51-F1. Primary workpiece materials are stainless steel, superalloys, and titanium (ISO material codes M and S). Secondary workpiece materials include steel and cast iron (ISO material codes P and K). Material grades M01, M10, M20, S10, and S20.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom personnel. Power down and de-energize the machine spindle before seating or removing inserts. Use the appropriate torx or hex key to secure the clamping screw to the toolholder manufacturer's specified procedure — do not overtighten, as this can chip the carbide substrate. Confirm insert seating and edge orientation before resuming operation.
