Description
The OSG Carbide 4 Flute End Mill with Corner Radius is a 16 mm diameter cutting tool designed for general machining tasks. Featuring a precise R0.5 corner radius, four flutes, and a regular-length body with center-cutting geometry, it delivers efficient material removal for milling, slotting, and profiling. The TiAlN coating enhances durability and wear resistance, helping maintain sharpness through demanding operations and longer production runs.
This end mill is built to perform across a broad range of materials and shop environments, making it a dependable choice for engineers, machinists, hobbyists, and technicians. The four-flute configuration provides good balance between chip evacuation and surface finish, enabling smooth operations from prototype work to routine production tasks.
- Corner Radius for Smoother Finishes: The 0.5 mm corner radius smooths entry and exit on corners, reduces chipping at sharp features, and yields cleaner, more consistent surface finishes with fewer passes.
- TiAlN Coating for Durability and Heat Resistance: TiAlN coating increases wear resistance and helps maintain cutting performance under higher temperatures, extending tool life in demanding materials and speeds.
- Four-Flute Design with Center-Cutting Capability: Four flutes provide efficient material removal and stable cuts, while center-cutting geometry enables plunging and versatile setups in pockets and fixtures for general machining.
With its combination of versatility, robust coating, and reliable geometry, this end mill helps you complete precise cuts more quickly, reduces downtime, and delivers consistent results across a wide range of general machining applications.
