Seco 03064508 Turning Insert WNMG432-M5 TK1501 Carbide

Product Description

The SECO 03064508 is a WNMG432-M5 indexable turning insert manufactured from solid carbide and finished with a CVD-applied Duratomic coating stack consisting of TiCN, Al2O3, and Cr layers. The trigon (W) shape provides an 80-degree included angle with a neutral hand orientation and a 0-degree rake angle, making it suited for stable, negative-rake toolholding setups. The insert measures 0.685 inches in length with a 0.5-inch inscribed circle diameter and a 0.0315-inch corner radius. Six cutting edges are available per insert, maximizing tool life per unit. Licensed machinists and CNC lathe operators install this insert in compatible WNMG-style toolholders for production turning applications.

This insert is designed for boring, facing, and turning operations. Its primary workpiece material designation is cast iron (ISO code K), with secondary suitability for steel and stainless steel (ISO codes P and M). Material grades K10, K20, and K30 are applicable. The M5 chip breaker geometry is suited for medium-depth interrupted and continuous cuts on a range of ferrous materials. The insert is held using clamp, pin, or lever-lock methods depending on the toolholder configuration. It conforms to both ANSI and ISO standards, with the ISO designation WNMG080408-M5.

Key Features

• CVD Duratomic coating (TiCN, Al2O3, Cr) for extended tool life on cast iron and steel
• 6 usable cutting edges per insert for reduced cost per edge
• M5 chip breaker geometry suited for medium-cut boring, facing, and turning
• Trigon (W) shape with 80-degree included angle and 0-degree clearance (N) for rigid negative-rake toolholding
• Chamfered and honed cutting edge preparation for consistent edge strength
• Compatible with clamp, pin, and lever-lock insert holding methods

Compatibility

Designed for use in WNMG-style indexable turning toolholders accepting a 432-size insert with clamp, pin, or lever-lock holding. Primary application is cast iron; secondary applications include steel and stainless steel per ISO material codes P and M. Conforms to ANSI and ISO standards (ISO designation WNMG080408-M5).

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque driver for the insert screw or clamping mechanism specified by the toolholder manufacturer — do not over-tighten, as carbide inserts are brittle and can fracture under excessive clamping force. Inspect the insert seat and chip pocket for debris before seating a new edge.
