490R-MM

ZANHO 490R-140408M-MM is a high-precision 90° square shoulder milling insert designed for versatile CNC operations. Featuring a sharp, positive rake geometry, it delivers light-cutting action with reduced power consumption and vibration. The specialized MM chipbreaker provides stable performance in both step and face milling, while its integrated 1.7mm wiper edge ensures an exceptional surface finish, making it a cost-effective alternative for standard CoroMill 490 systems.

Key Technical Advantages

  • True 90° Square Shoulders: Engineered to produce exact 90-degree corners with minimal mismatch, ideal for high-precision step milling and pocketing.
  • Light Cutting Action: The large positive rake angle and sharp cutting edge reduce axial and radial forces, allowing for stable machining even on low-power spindles.
  • Superior Surface Finish: Includes a wide 1.7mm wiper flat (Bs) that acts as a smoothing tool, delivering high-quality surface results during face milling operations.
  • Stable MM Chipbreaker: The universal MM geometry optimizes chip formation and evacuation, preventing chip re-cutting and enhancing tool life across varied milling conditions.
  • 4 High-Precision Edges: Provides four usable edges per insert, offering excellent economic value and reduced cost-per-component.
