Seco 00004381 Milling Insert OFER070405TN-ME15 F40M Carbide

Product Description

The SECO 00004381 is a solid carbide milling insert carrying manufacturer part number OFER070405TN-ME15 and grade F40M. It features an octagon shape with eight cutting edges, a positive rake angle of 16 degrees, and a T-Land cutting edge style. The insert is coated via PVD with a TiAlN and TiN multilayer finish, which supports heat resistance and extended tool life in demanding milling operations. At 0.1795 inches thick and 0.7063 inches wide, it fits the OFER-07 series insert pocket and is held in place using a wedge clamp. This insert is installed by machinists and tooling technicians in CNC milling applications across job shops and production environments.

This insert is designed for milling steel, stainless steel, cast iron, non-ferrous metal, superalloys, and titanium. Primary material application codes are P, K, and S, with secondary coverage for K and N workpiece categories per ISO classification. The ME15 chip breaker geometry is suited for a range of cut depths up to 0.2795 inches, making this insert applicable across roughing and semi-finishing passes. It is compatible with the R220.43-07 cutter series. Each package contains one insert, with a minimum order quantity of 10 pieces.

Key Features

• Solid carbide fine grain substrate with PVD-applied TiAlN and TiN coating for wear resistance
• Octagon insert shape with 8 cutting edges and 135-degree included angle for extended insert life per edge
• Positive rake geometry at 16 degrees with T-Land cutting edge style reduces cutting forces
• ME15 chip breaker supports controlled chip evacuation across steel and superalloy applications
• Maximum depth of cut of 0.2795 inches with a cutting edge effective length of 0.2921 inches
• Neutral hand orientation and wedge clamp holding method for secure, repeatable seating

Compatibility

Designed for use with the R220.43-07 cutter series. ANSI and ISO code OFER070405TN-ME15 confirms direct fitment in toolholders specified for the OFER-07 insert series with a 0.7000 to 1.0000 inch inscribed circle range.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torque wrench and wedge clamp hardware specified by the cutter body manufacturer — do not overtighten or use improvised clamping tools. Inspect the insert pocket and seating surfaces for chips or wear before installing a new insert.
