Seco 03062604 Turning Insert CNMG432-M6 TK1501 Carbide

Product Description

The SECO 03062604 is a solid carbide CNMG432-M6 turning insert with a TK1501 grade and a multilayer CVD coating of TiCN, Al2O3, and Cr under the Duratomic coating classification. It features an 80-degree diamond (rhombic) insert shape, a negative rake and negative side clearance geometry, and an M6 chip breaker designed for roughing and medium machining operations. With four cutting edges and a honed cutting edge style, this insert delivers high wear-resistance balanced with toughness across a range of workpiece materials. It is installed in standard CNMG-style toolholders and used by machinists and CNC operators in production turning environments.

This insert is suited for turning, boring, and facing operations on cast iron, steel, and stainless steel workpieces. The TK1501 grade targets high wear-resistance to moderate wear-resistance and toughness for P (steel), M (stainless steel), and K (cast iron) material groups. The M6 chip breaker geometry supports chip control in both roughing and medium-depth passes, making this insert a practical choice for general production work and interrupted cuts requiring a balance of edge strength and surface finish.

Key Features

• TK1501 grade CVD multilayer coating: TiCN, Al2O3, and Cr (Duratomic classification) for wear-resistance across P, M, and K material groups
• 80-degree diamond (C-shape) insert with negative rake and negative side clearance for strong, supported cutting edge
• M6 chip breaker optimized for roughing and medium machining chip control
• Four cutting edges per insert for extended tool life and cost efficiency
• Honed cutting edge style reduces micro-chipping and improves edge stability
• Compatible with clamp, pin, and lever lock toolholder holding methods
• Meets ANSI and ISO standards; ANSI code CNMG432, ISO code CNMG120408-M6

Compatibility

Designed for use in CNMG-style toolholders that accept a 1/2-inch inscribed circle, negative rake insert with clamp, pin, or lever lock holding methods. Suitable for boring, facing, and turning applications on steel, stainless steel, and cast iron.

Installation Notes

Installation is performed by machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or replacing inserts. Ensure the toolholder pocket and clamping surfaces are clean and free of chips before installing a new insert. Use the appropriate torque wrench for the clamping screw per the toolholder manufacturer specifications and do not overtighten, as this can cause insert fracture.
