Seco 02828067 Milling Insert ONMU050410ANTN-M11 MK2050

Product Description

The SECO 02828067 is a solid carbide milling insert carrying the manufacturer designation ONMU050410ANTN-M11 in the MK2050 grade. It features an octagonal shape with 16 cutting edges and a double-sided design, maximizing tool life between index cycles. The insert is coated with a TiSiN and TiAlN multilayer finish applied via PVD process, providing thermal and wear resistance suited to high-speed milling. A negative rake angle of 20 degrees combined with a T-Land cutting edge style delivers controlled chip formation. The M11 chip breaker geometry targets stable cutting in cast iron and steel applications. This insert is installed by machinists and CNC tooling technicians working with compatible SECO milling cutter bodies.

This insert is designed for face milling and shoulder milling operations where cast iron is the primary workpiece material, with secondary suitability for steel and hard materials. The ONMU-05 series geometry and neutral hand orientation make it applicable to a range of horizontal and vertical machining center setups. It is compatible with SECO cutter series R217.48-05 and R220.48-05. The maximum depth of cut is 0.1339 inches, and the cutting edge effective length matches that value, making this insert well suited to finish and semi-finish milling passes in ferrous materials.

Installation Notes

This insert is installed and indexed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before removing or installing any insert. Use the appropriate torx or hex key to seat the insert screw to the cutter body manufacturer torque specification found in the cutter body documentation. Inspect the pocket seat and clamping screw for wear or damage before installing a fresh insert.
