Seco 00093064 Milling Insert LNKT080531PPTN-M06 F40M Carbide

Product Description

The SECO 00093064 is a solid carbide milling insert carrying the ANSI and ISO designation LNKT080531PPTN-M06 and manufactured to the F40M fine-grain grade. The insert features a rectangular shape with a neutral hand orientation, a negative rake angle of 15 degrees, and a T-Land cutting edge style. Two double-sided cutting edges are available per insert, maximizing tool life between index cycles. A PVD-applied TiAlN and TiN dual-layer coating delivers thermal and wear resistance suited to interrupted cuts and demanding feed rates. Thickness measures 0.1969 inches and the inscribed circle diameter is 0.2953 inches. The insert is held in the cutter body by screw clamping and is compatible with the R335.18 cutter series. The M06 chip breaker geometry controls chip flow across the targeted workpiece materials.

This insert is designed for milling applications in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering ISO material codes P, K, S, and N. It is suited to both roughing and semi-finishing passes where consistent chip control and edge stability are required. The R335.18 cutter series compatibility makes it applicable to square-shoulder milling operations in production machining environments. Machinists and tooling technicians working on CNC vertical and horizontal machining centers are the primary end users. The included 90-degree angle geometry enables true square-shoulder profiling when the insert is seated correctly in the cutter body.

Key Features

• F40M fine-grain solid carbide substrate with PVD TiAlN and TiN dual-layer coating for extended wear resistance
• Double-sided insert with 2 cutting edges per insert, reducing per-edge tooling cost
• Neutral hand, negative rake geometry with 15-degree rake angle and T-Land cutting edge style
• M06 chip breaker optimized for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium
• Maximum depth of cut of 0.2953 inches with a cutting edge effective length of 0.2953 inches
• Screw-held mounting compatible with R335.18 cutter series for square-shoulder milling

Compatibility

Compatible with the R335.18 cutter series. This insert carries the ANSI and ISO code LNKT080531PPTN-M06 and belongs to the LNKT-08 series. It is rated for primary workpiece materials including steel, cast iron, superalloys, and titanium (ISO codes P, K, S) and secondary materials including cast iron and non-ferrous metals (ISO codes K, N).

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or indexing inserts. Use the correct torx or hex key specified by the cutter body manufacturer when tightening the clamping screw — do not overtighten, as this can fracture the carbide insert. Inspect the insert seat and clamping screw for wear or contamination before each insert change.
