Seco 00076807 Milling Insert OFMT050405TR-ME12 F40M Carbide

Product Description

The SECO 00076807 is a solid carbide milling insert carrying the ANSI/ISO designation OFMT050405TR-ME12 and manufacturer grade F40M. It features an octagon shape with 8 cutting edges and a right-hand cutting orientation. The insert is PVD-coated with a TiAlN and TiN multilayer finish, delivering wear resistance across a wide range of workpiece materials. An ME12 chip breaker geometry combined with an 18-degree rake angle and T-Land cutting edge style supports controlled chip formation during face and shoulder milling operations. The insert is held in the cutter body by a screw-clamp method and is rated as a multi-use tool suitable for single-sided use.

This insert is designed for milling applications in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Primary workpiece material codes are P, K, and S, with secondary coverage of K and N materials. Typical install scenarios include face milling, shoulder milling, and general-purpose metal removal on CNC machining centers. The insert is compatible with SECO cutter series R217.43-05 and R220.43-05. It suits production environments where tool change frequency and edge count per insert directly affect cost per edge.

Key Features

• Octagon insert shape with 8 cutting edges maximizes cost per edge on compatible cutter bodies
• F40M fine-grain solid carbide substrate with PVD-applied TiAlN and TiN coating for thermal and wear resistance
• ME12 chip breaker geometry with 18-degree rake angle and T-Land edge style for controlled chip flow
• 0.0197-inch corner radius suitable for light-to-medium finishing and semi-finishing passes
• Maximum depth of cut of 0.1024 inches with a cutting edge effective length of 0.2161 inches
• Right-hand, single-sided insert held by screw clamp; meets ISO dimensional standards

Compatibility

Designed for use in SECO cutter series R217.43-05 and R220.43-05 milling cutter bodies that accept OFMT-05 series inserts. Verify seat geometry and screw specification against the cutter body documentation before installation.

Installation Notes

Insert seating and replacement is performed by machining technicians or tool crib personnel following the cutter body manufacturer torque guidelines for the screw-clamp retention system. Power down and lock out the spindle before changing inserts. Inspect the insert pocket seat and clamping screw for wear or debris before seating a new insert. Never force an insert into a damaged or contaminated pocket, as improper seating can cause insert fracture or dimensional inaccuracy during the cut.
