Product Description
The SECO 02959927 is a WNMG331-M3 trigon-style indexable turning insert manufactured from solid carbide and finished with a CVD-applied Duratomic multilayer coating (TiCN, Al2O3, Cr). It carries the TP2501 manufacturer grade, placing it in the P10-P35 material grade range suited for general and interrupted steel turning at moderate to high cutting speeds. The insert features a neutral hand orientation, a chamfered and honed cutting edge style, and the M3 chip breaker geometry. With 6 available cutting edges and compatibility with clamp, pin, and lever lock holding methods, it delivers consistent tool life across high-volume turning operations. Designed for productive use in boring, facing, and turning applications.
This insert is intended for CNC and manual lathe operations on steel as the primary workpiece material, with stainless steel and cast iron as secondary applications. The M3 chip breaker geometry handles medium-depth finishing and semi-finishing passes well. The insert conforms to both ANSI and ISO standards, with the ISO code WNMG060404-M3 providing direct cross-reference to global tooling catalogs. It is sold individually (package quantity of 1) with a minimum order quantity of 10 units. Trade machinists, tooling engineers, and CNC setup technicians are the typical end users for this insert type.
Key Features
- CVD Duratomic multilayer coating: TiCN, Al2O3, and Cr layers for wear and heat resistance in steel cutting
- M3 chip breaker geometry suited for medium-depth semi-finishing and finishing passes
- 6 cutting edges per insert for extended tool economy
- Neutral hand orientation accepts clamp, pin, and lever lock holding methods
- Chamfered and honed cutting edge style reduces micro-chipping on entry and exit
- Conforms to ANSI and ISO standards; ISO code WNMG060404-M3
Compatibility
Designed for use in toolholders accepting WNMG-style trigon inserts with clamp, pin, or lever lock holding methods. Primary workpiece material is steel (ISO P); secondary materials include stainless steel (ISO M) and cast iron (ISO K). Suitable for boring, facing, and turning operations.
Installation Notes
Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing the insert. Ensure the insert pocket and seating surface are clean and free of chips before clamping to avoid seating errors that can cause premature edge failure. Do not exceed the maximum depth of cut stated in the toolholder manufacturer specifications for this insert geometry.
