Seco 00091089 Mdt Turning Insert LCMF1604080400FT CP500

Product Description

The SECO 00091089 is a double-ended, multi-directional turning insert from the MDT series, designed for grooving and turning operations on CNC lathes and turning centers. Manufactured from micrograin solid carbide with a CP500 grade and a PVD coating, this insert delivers consistent edge integrity and wear resistance across a broad range of workpiece materials. The neutral hand orientation allows use in multiple cutting directions, and the FT chipbreaker geometry supports reliable chip control during shallow-depth turning passes. It carries a relief angle of 7 degrees and is classified under insert style LCMF with a style designation of LCMF160408-0400-FT.

This insert is suited for machining a wide range of materials, including hardened steels, cast irons, stainless steels, non-ferrous alloys, general-purpose steels, and heat-resistant superalloys, corresponding to ISO material codes H, K, M, N, P, and S. It is appropriate for both light and moderate cutting applications where dimensional accuracy and surface finish consistency are required. Typical installations are performed by CNC machinists and toolroom technicians in production turning environments using MDT-compatible toolholders.

Key Features

• Micrograin solid carbide substrate with CP500 grade for extended tool life
• PVD coating process provides a hard, wear-resistant surface layer
• Double-ended insert design doubles usable cutting edges per insert
• Neutral hand orientation supports multi-directional cutting paths
• FT chipbreaker geometry assists with chip evacuation in turning and grooving
• Compatible with ISO material groups H, K, M, N, P, and S workpiece materials

Compatibility

Designed for use in MDT-series toolholders and systems that accept LCMF-style inserts with a 160408 size code. Verify toolholder pocket specifications against the LCMF160408-0400-FT style designation before installation.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine before changing inserts. Use the appropriate torque wrench and insert screw specified by the toolholder manufacturer — do not overtighten the clamping screw, as this can fracture the carbide body. Inspect the insert pocket for wear or debris before seating the new insert.
