Description
The SECO 02722345 is a solid carbide milling insert carrying the ANSI and ISO designation ONMU090520ANTN-ME13 in manufacturer grade F40M. The insert features an octagonal shape with 16 cutting edges, making it a high-utilization double-sided insert well suited for production milling environments. A PVD-applied TiAlN and TiN dual-layer coating provides wear resistance across a range of workpiece materials. The ME13 chip breaker geometry and negative rake angle with T-Land cutting edge style are engineered to manage chip formation during interrupted and continuous cuts. Thickness measures 0.2677 inches and the inscribed circle diameter is 0.8661 inches.
This insert is intended for face and shoulder milling applications on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It is a neutral-hand insert suitable for both right-hand and left-hand cutter bodies. The relief angle is 0 degrees with a rake angle of 20 degrees. Typical users include CNC machinists, tool and die shops, and production machining operations working with general steels and difficult-to-machine alloys. The insert is held in the cutter body by screw clamping. Sold individually with a minimum order quantity of 10 units.
Key Features
- Octagon insert shape with 16 cutting edges maximizes index count per insert
- Double-sided design doubles usable cutting edges versus single-sided equivalents
- PVD-applied TiAlN and TiN coating for thermal resistance and extended tool life
- ME13 chip breaker optimized for steel, cast iron, and superalloy milling
- Negative rake with T-Land edge style supports stable cuts on hard and interrupted surfaces
- Compatible with R220.48-09 and L220.48-09 cutter series bodies
Compatibility
Designed for use with SECO cutter series R220.48-09 and L220.48-09 milling bodies. The ONMU-09 series insert format governs body compatibility; verify cutter pocket geometry before installation.
Installation Notes
Installation is performed by qualified machinists or tooling technicians following the cutter body manufacturer torque guidelines for the clamping screw. Ensure the machine spindle is fully stopped and locked out before indexing or replacing inserts. Inspect the pocket seat and screw threads for chips or damage before seating a new insert. Follow ISO and shop safety standards for handling carbide cutting tools.
