Seco 02509330 Milling Insert SNHQ120431ER2-M07 F40M Carbide

Product Description

The SECO 02509330 is a solid carbide milling insert carrying ANSI and ISO designation SNHQ120431ER2-M07 in manufacturer grade F40M. This single-sided, square-shaped insert is produced from fine-grain solid carbide and features a dual PVD coating of TiAlN and TiN, delivering heat and wear resistance suited to demanding milling operations. The insert carries a negative rake angle of 20 degrees, a honed cutting edge style, and provides two cutting edges per insert. It is designed for right-hand cutting in milling applications where consistent edge life and surface finish are required across a range of workpiece materials. Licensed machinists and tooling specialists typically select this insert for use on CNC milling platforms.

This insert is intended for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Primary material application codes are P, K, and S, with secondary coverage of K and N classifications. It fits within the SNHQ-12 series and is specifically listed as compatible with cutter series 335.19-12. Typical install scenarios include face milling and shoulder milling on production CNC machining centers handling ferrous and exotic alloy workpieces. The M07 chip breaker geometry is optimized for moderate to heavy stock removal on these material groups.

Compatibility

Listed as compatible with cutter series 335.19-12. Designated for the SNHQ-12 insert series. Screw-held mounting method. Verify toolholder pocket specifications against the ANSI and ISO code SNHQ120431ER2-M07 before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the spindle drive before seating or removing inserts. Use the appropriate torx or hex key to torque the clamping screw to the toolholder manufacturer's specified value — do not estimate torque by feel. Inspect the insert pocket and seating surface for chips or debris before installing a fresh insert, as contamination will affect runout and edge life.
