Seco 02730829 Wnmg 433-MF5 TH1000 Carbide Turning Insert

Product Description

The SECO 02730829 is a solid carbide indexable turning insert in the WNMG 433-MF5 series, designed for high-performance metal cutting in CNC turning, boring, and facing operations. It carries a TiAlSiN multilayer PVD coating under the manufacturer grade TH1000, engineered for heat resistance and wear performance in demanding cuts. The insert features an 80-degree trigon shape, a neutral hand orientation, a 0.5-inch inscribed circle, and a corner radius of 0.0472 inches (3/64 inches). With 6 usable cutting edges and a chamfered-and-honed cutting edge style, it delivers consistent performance across multiple index positions. Installed by machinists and CNC turning specialists, this insert is a direct catalog replacement for standard WNMG 433-MF5 tooling.

This insert is suited for turning, boring, and facing operations on superalloys, titanium, and hard materials — material grade designations S05 and H05. It is a negative-rake insert with an MF5 chip breaker geometry, optimized for finishing and semi-finishing passes on difficult-to-machine workpiece materials. It meets both ANSI and ISO standards, with the ISO code WNMG080412-MF5 and the industry standard number WNMG433-MF5. It is compatible with toolholders that accept WNMG-style inserts using clamp, pin, or lever-lock holding methods.

Key Features

• TiAlSiN multilayer PVD coating (TH1000 grade) for heat and wear resistance on superalloys and hard materials
• 80-degree trigon insert shape with 6 cutting edges for maximum index value per insert
• MF5 chip breaker geometry optimized for finishing and semi-finishing on difficult materials
• Chamfered and honed cutting edge style for edge stability and reduced chipping
• Negative rake, neutral hand — compatible with standard WNMG lever-lock, clamp, and pin-style toolholders
• Meets ANSI and ISO standards; ISO code WNMG080412-MF5

Compatibility

Designed for use in WNMG-style toolholders accepting clamp, pin, or lever-lock insert retention. Primary workpiece material compatibility is superalloys and titanium (code S) and hard materials (code H), per material grades S05 and H05. Conforms to ANSI and ISO WNMG080412-MF5 standards, ensuring fitment with any standard WNMG 433 toolholder pocket.

Installation Notes

Installation is performed by a qualified machinist or CNC turning technician. Power down and lock out the machine spindle before indexing or replacing the insert. Seat the insert fully in the toolholder pocket and verify the clamp, pin, or lever-lock mechanism is secure before resuming cuts. Do not exceed the maximum depth of cut specified for the toolholder and insert combination in use.
