Seco 02526642 Milling Insert SNHQ120708TL4-M07 F40M Carbide

Product Description

The SECO 02526642 is a solid carbide milling insert carrying ANSI and ISO designation SNHQ120708TL4-M07 in manufacturer grade F40M. This square-shaped, single-sided insert is designed for indexable milling applications requiring reliable performance across a range of ferrous and exotic workpiece materials. The TiAlN and TiN dual-layer PVD coating provides thermal resistance and wear protection, while the fine-grain carbide substrate supports edge integrity under aggressive cutting conditions. With four cutting edges, a negative rake geometry, and a T-Land cutting edge style, the insert delivers controlled chip formation and predictable tool life in production milling environments. Licensed machinists and CNC toolroom technicians are the primary installers.

This insert is suited for face milling, shoulder milling, and general-purpose indexable milling operations on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It is compatible with the SECO cutter series 335.19-12 and carries an insert size code of 120708. The left-hand insert hand designation must be matched to the appropriate cutter body orientation. Typical applications include roughing to semi-finishing passes on steel and cast iron components in job shop and production machining environments.

Key Features

• Solid carbide fine-grain substrate with PVD-applied TiAlN and TiN dual coating for extended wear life
• Square insert shape with 90-degree included angle and four usable cutting edges per insert
• T-Land cutting edge style with negative rake and M07 chip breaker geometry for controlled chip evacuation
• Left-hand insert designation for use with compatible left-hand cutter bodies in the 335.19-12 series
• Maximum depth of cut of 0.2441 inches with a corner radius of 0.0315 inches
• Primary workpiece material compatibility spans steel, cast iron, superalloys, and titanium (ISO material codes P, K, S)

Compatibility

Designed for use with SECO cutter series 335.19-12 indexable milling cutter bodies requiring SNHQ-12 series inserts. Cutter body and insert hand must be verified before installation. Compatible cutter bodies must accept a screw-held, single-sided square insert with a 0.5000-inch inscribed circle.

Installation Notes

Insert replacement and indexing should be performed by a qualified machinist or CNC toolroom technician with the machine powered down and locked out per facility lockout/tagout procedures. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert. Use the correct torque driver per the cutter body manufacturer specification for the insert clamping screw — do not overtighten. Confirm insert hand orientation matches the cutter body before resuming operation.
