Seco 02808728 Milling Insert XNHQ140708TN4-M11 F40M

Product Description

The SECO 02808728 is a solid carbide milling insert with ANSI and ISO designation XNHQ140708TN4-M11, manufactured in the F40M fine-grain carbide grade and designed for use in milling operations across a broad range of workpiece materials. The insert features a butterfly (XNHQ) shape with a double-sided, neutral-hand configuration, providing four usable cutting edges per insert. A PVD-applied TiAlN and TiN dual coating delivers thermal resistance and wear protection during high-speed milling. The M11 chip breaker geometry suits medium machining conditions. Installed by machinists and CNC tooling technicians, this insert seats via screw-clamp holding in compatible cutter bodies.

This insert is suited for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium in both roughing and semi-finishing applications. The negative rake angle and T-Land cutting edge style support stable engagement in interrupted cuts and hard materials. The XNHQ140708TN4-M11 is compatible with the SECO Cutter Series 335.25 and fits toolholders and cutter bodies designed for the XNHQ-14 insert series. It is sold individually with a minimum order quantity of 10 units.

Key Features

• Solid carbide fine-grain substrate (F40M grade) for toughness and wear resistance in demanding milling applications
• PVD-applied TiAlN and TiN dual coating for elevated thermal and oxidation resistance
• Double-sided insert with 4 cutting edges to maximize tool life per insert
• M11 chip breaker geometry engineered for medium-duty milling of steel, cast iron, and superalloys
• Negative rake angle with T-Land cutting edge for stable, secure cutting engagement
• Neutral hand orientation for flexible use in a range of cutter body configurations

Compatibility

Designed for use with SECO Cutter Series 335.25 and cutter bodies accepting XNHQ-14 series inserts. ANSI and ISO code XNHQ140708TN4-M11 can be used to verify fitment with compatible toolholders. Primary workpiece material codes P, K, and S indicate suitability for steel, cast iron, and superalloys and titanium.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and de-energize the machine spindle before seating or replacing inserts. Use the appropriate torx or hex key per the cutter body manufacturer specification to secure the crew clamp; do not overtighten. Inspect the insert pocket and seating surface for debris or damage before installing a new insert to ensure proper seating and cutting edge alignment.
