Precision-crafted by Sumitomo, the WNMG080408N-UP inserts are premium-grade, double-sided turning inserts designed for high-efficiency machining of steel and stainless steel. Featuring a negative 80° trigon (triangular) shape with six usable cutting edges, these inserts offer excellent cost-per-edge value for medium to finishing applications.

The UP chipbreaker geometry provides smooth cutting action with low cutting forces, making it ideal for operations that demand a superior surface finish and reliable chip evacuation — even on tougher materials or interrupted cuts.

Key Features:

Insert Style: WNMG080408 – 80° trigon, double-sided, 6 cutting edges
Chipbreaker: UP – optimized for finishing to medium turning
Material Compatibility: Designed primarily for stainless steel and steel (including alloy and carbon steels)
Applications: Light to medium cuts, finishing operations
Finish Quality: Excellent surface finish with minimal vibration or chatter
Grade Options: Typically offered in high-performance CVD/PVD-coated grades for long tool life and heat resistance

These inserts are ideal for use on CNC lathes and turning centers in industries requiring tight tolerances, clean finishes, and consistent chip control — such as automotive, energy, and general engineering sectors.
