Seco 02509331 Milling Insert Snhq 120431EL2M07 F40M

Product Description

The SECO 02509331 is a solid carbide milling insert carrying the ANSI designation SNHQ120431EL2-M07 and manufacturer grade F40M. Designed for use in milling operations, this single-sided, left-hand insert features a square shape with a 90-degree included angle and a negative rake geometry set at 20 degrees. The cutting edge is honed for consistent entry and is coated with TiAlN and TiN via a PVD process, providing heat and wear resistance across demanding cutting applications. Thickness measures 0.1575 inches, with an inscribed circle diameter of 0.5000 inches. Licensed machinists and CNC tooling technicians are the primary installers of this insert type.

This insert is suited for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The M07 chip breaker geometry is optimized for medium-range cutting conditions across these material groups. The insert fits the SECO cutter series 335.19-12 and is held in place by a screw-type clamping method. It is compatible with applications requiring ISO-standard tooling and is appropriate for both roughing and semi-finishing passes depending on feed and depth parameters. Maximum depth of cut is 0.1437 inches. This insert is sold individually, with a minimum order quantity of 10 units.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the pocket and tighten the clamping screw to the toolholder manufacturer's specified torque. Inspect the insert pocket and seating surface for chips or debris before installation to ensure proper contact and runout.
