Seco 02809325 Milling Insert XNHQ140750TN4-M11 F40M Carbide

Product Description

The SECO 02809325 is a solid carbide milling insert carrying ANSI and ISO designation XNHQ140750TN4-M11 in manufacturer grade F40M. It features a butterfly-shaped, double-sided, negative-rake geometry with a T-Land cutting edge style and a 90-degree included angle. The insert is PVD-coated with TiAlN and TiN for heat and wear resistance. It provides 4 cutting edges and a maximum depth of cut of 0.5157 inches, making it suited for productive face and shoulder milling operations. The part weighs approximately 0.03 pounds and is sold individually, with a minimum order quantity of 10 units.

This insert is designed for use in shoulder milling applications where precision and tool life under demanding conditions are required. Primary workpiece materials include steel, cast iron, and superalloys and titanium. Secondary applications cover cast iron and non-ferrous metals. The insert is compatible with the SECO 335.25 cutter series and uses the M11 chip breaker geometry, which is optimized for medium-duty milling passes across a broad range of ferrous and non-ferrous materials. Installation is performed by licensed machinists and toolroom professionals in both production and maintenance machining environments.

Compatibility

Designed for use with the SECO 335.25 cutter series. Insert size code 140750 corresponds to ANSI and ISO code XNHQ140750TN4-M11 within the XNHQ-14 series.

Installation Notes

This insert is installed and indexed by qualified machinists following standard toolroom procedures. Power down and lock out the machine spindle before seating, indexing, or replacing inserts. Use the correct torx or hex key for the clamping screw and tighten to the toolholder manufacturer's specified torque rather than guessing. Inspect the insert pocket and clamping screw for wear or damage before each insert change to ensure proper seating and runout control.
