Seco 02526618 Milling Insert SNHQ120412TR4-M07 F40M Carbide

Product Description

The SECO 02526618 is a solid carbide milling insert carrying ANSI and ISO designation SNHQ120412TR4-M07 and manufacturer grade F40M. The insert features a square shape with a 90-degree included angle, a negative rake geometry with a T-Land cutting edge style, and an M07 chip breaker designed for controlled chip formation in demanding milling applications. Applied via PVD process, the dual TiAlN and TiN coating delivers thermal resistance and surface hardness suited to high-speed cutting. With four usable cutting edges on a single-sided insert, this fine-grain carbide tool is intended for use by machinists and CNC tooling technicians working in production or job-shop environments.

The SNHQ120412TR4-M07 insert is designed for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It is compatible with cutter bodies in the 335.19-12 series and targets right-hand cutting setups. Its inscribed circle of 0.5 inches and 0.1575-inch thickness fit the SNHQ-12 series insert pocket specifications. Typical applications include face milling, shoulder milling, and general-purpose milling where consistent tool life across difficult workpiece materials is required.

Key Features

• Solid carbide fine-grain substrate with PVD-applied TiAlN and TiN dual coating for thermal and wear resistance
• Four cutting edges per insert on a square, single-sided body for cost-effective tooling management
• M07 chip breaker geometry engineered for steel, cast iron, superalloys, and titanium workpieces
• Negative rake angle with T-Land cutting edge style reduces insert breakage on interrupted cuts
• Maximum depth of cut of 0.1437 inches with a corner radius of 0.0472 inches (3/64 inch)
• Screw-held mounting method ensures positive insert location and repeatable edge indexing

Compatibility

Designed for use with cutter bodies in the 335.19-12 series. Insert conforms to ANSI and ISO code SNHQ120412TR4-M07 and fits SNHQ-12 series toolholders accepting a 0.5-inch inscribed circle, screw-held square insert pocket.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Before indexing or replacing inserts, de-energize the machine and follow lockout/tagout procedures per applicable shop safety standards. Use the correct torque wrench and clamping screws specified by the cutter body manufacturer to seat the insert properly. Inspect the insert pocket for debris or damage before seating a new edge to avoid insert rocking or premature failure.
