Product Overview
WNMG-BM is an 80° peach-shaped double-sided indexable carbide turning insert with a professionally optimized BM chipbreaker and high-quality golden PVD coating. It is specially developed for semi-finishing turning of stainless steel and is also suitable for processing ordinary carbon steel.
- The 80° corner structure ensures high nose strength
- Double-sided six-edge design greatly improves insert utilization and reduces processing costs
- Optimized BM chipbreaker effectively reduces cutting resistance
- Solves common processing problems of austenitic stainless steel including tool adhesion, built-up edge, and chip entanglement
- Enables stable chip breaking performance
- PVD coating features thin thickness, strong adhesion, low friction, excellent edge toughness, anti-adhesion, and wear resistance
- Prevents edge chipping and reduces workpiece burrs
- Supports multiple turning processes including outer circle turning, facing, and profiling
- Adapts to continuous and light interrupted cutting conditions
Technical Parameters
Application: General turning of steel semi-finishing
Chipbreaker: BM chipbreaker
Recommended Grade: Typically used with PVD grades such as HR7225 / HR7125
