Seco 02526586 Milling Insert SNHQ110208TL4-M07 F40M Carbide

Product Description

The SECO 02526586 is a solid carbide milling insert carrying manufacturer part number SNHQ110208TL4-M07 in the F40M grade. It features a square shape with a 90-degree included angle, a negative rake geometry with a T-Land cutting edge style, and a PVD-applied TiAlN and TiN dual-layer coating for wear resistance at elevated cutting temperatures. The insert measures 0.0906 inches thick with an inscribed circle diameter of 0.4331 inches and a corner radius of 0.0315 inches (1/32 inch). Four cutting edges are available on this single-sided, left-hand insert. The M07 chip breaker geometry is designed for controlled chip formation across a range of depths up to 0.0827 inches. Licensed machinists and CNC tooling specialists are the primary installers.

This insert is suited for milling operations on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium — covering ISO material codes P, K, S, and N. It is a fine-grain carbide insert intended for demanding face and shoulder milling applications where consistent edge life and chip control are critical. The insert mounts by screw-holding method and is compatible with the SECO cutter series 335.19-11, making it appropriate for both roughing and semi-finishing passes on a broad range of workpiece materials in production machining environments.

• M07 chip breaker geometry supports controlled chip formation across multiple material types
• Four available cutting edges per insert on a left-hand, single-sided design
• Maximum depth of cut of 0.0827 inches with a T-Land cutting edge style for edge reinforcement

Compatibility

Confirmed compatible with SECO cutter series 335.19-11. Insert conforms to ANSI and ISO code SNHQ110208TL4-M07 within the SNHQ-11 series. Screw-held mounting is required.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine spindle before seating or indexing inserts. Use the correct torx or hex key specified by the toolholder manufacturer to achieve proper clamping torque — do not over-torque the mounting screw, as this can fracture the carbide body. Inspect the insert seat and pocket for debris or damage before each insert change to ensure full seating and repeatable tool projection.
