Seco 02688970 Milling Insert ONMU090520ANTN-M13 MP3000

Product Description

The SECO 02688970 is a solid carbide milling insert carrying the ANSI and ISO designation ONMU090520ANTN-M13 in manufacturer grade MP3000. This double-sided, octagon-shaped insert features 16 cutting edges and a TiAlN coating applied via PVD process, making it well suited for high-productivity milling operations on hard materials, steel, and stainless steel. It measures 0.8661 inches in inscribed circle diameter and 0.2677 inches thick, with a maximum depth of cut of 0.3031 inches. The negative rake geometry and T-Land cutting edge style provide edge strength and stability during interrupted cuts. Installation is performed by licensed machinists or tooling specialists in CNC milling applications.

This insert is designed for use in face milling, shoulder milling, and general milling operations where hard materials, steel, and stainless steel are the primary workpiece materials. The M13 chip breaker geometry supports controlled chip formation across a range of feed rates. The insert is compatible with the SECO cutter series R220.48-09 and L220.48-09, making it a direct-fit option for those tooling platforms in both roughing and semi-finishing passes.

Key Features

• Double-sided octagon insert with 16 usable cutting edges for extended tool life
• TiAlN coating via PVD process for heat resistance and wear performance on hard and ferrous materials
• Negative rake angle with T-Land cutting edge style for improved edge strength
• M13 chip breaker geometry supports steel, stainless steel, and hard material applications
• Micrograin carbide substrate for consistent edge integrity at elevated cutting speeds
• Screw-held mounting method for secure, repeatable insert positioning

Compatibility

Compatible with SECO cutter series R220.48-09 and L220.48-09. Rated for primary workpiece material code H (hard material) and secondary codes P (steel) and M (stainless steel) per ISO material classification.

Installation Notes

Insert seating and screw torque should follow the cutter body manufacturer specifications provided with the toolholder. Ensure the milling cutter body is fully de-energized and spindle is locked before changing inserts. Use the correct Torx or hex key supplied or specified by the cutter body manufacturer to avoid seat damage. Inspect the insert pocket and clamping screw for wear or contamination before seating a new insert.
