Seco 02809863 Milling Insert ONMU050410ANTN-ME11 F40M Carbide

Product Description

The SECO 02809863 is a solid carbide milling insert carrying ANSI and ISO designation ONMU050410ANTN-ME11 in manufacturer grade F40M. The insert features an octagonal shape with 16 cutting edges, a neutral hand orientation, and a negative rake geometry with a 20-degree rake angle. A TiAlN plus TiN coating applied via PVD process provides wear and heat resistance during aggressive milling operations. The ME11 chip breaker geometry and T-Land cutting edge style help manage chip flow and edge stability across a range of workpiece materials. This is a double-sided insert, maximizing the number of usable edges per unit and reducing tooling cost per cut.

This insert is suited for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium in both roughing and finishing applications. Primary material codes are P, K, and S, with secondary coverage of K and N material groups. It is appropriate for use in CNC machining centers in production environments where consistent edge life and surface finish across difficult materials are required. Installation is performed by a machinist or tooling technician using a screw-holding method.

Key Features

• Octagonal insert shape with 16 cutting edges for maximum edge utilization per insert
• Double-sided design extends usable life before replacement
• TiAlN plus TiN PVD coating for elevated wear resistance in steel, cast iron, and superalloy applications
• ME11 chip breaker with T-Land edge style for controlled chip formation and edge protection
• Negative rake geometry (20-degree rake angle) with zero relief angle for robust edge strength
• Fine grain solid carbide substrate in manufacturer grade F40M for toughness and thermal stability

Compatibility

Compatible with SECO cutter series R217.48-05 and R220.48-05 as stated by the manufacturer. Insert size code 050410 with ANSI and ISO code ONMU050410ANTN-ME11.

Installation Notes

Installation is performed by a qualified machinist or tooling technician using the screw-holding method standard for ONMU-style insert pockets. Ensure the machine spindle is fully stopped and the tool is secured in a vise or holder before seating or removing inserts. Verify the pocket seating surface is clean and free of chips or debris before tightening the clamping screw to avoid insert rocking or premature edge failure. Follow the toolholder manufacturer torque guidelines for the clamping screw.
