Description
The OSG Carbide 4 Flute End Mill with Corner Radius and TiAlN coating is a regular-length, center-cutting cutting tool designed for general machining tasks. Sized at 5 mm in diameter with an R1 corner radius, it delivers precise milling, slotting, and profiling across a wide range of materials and everyday applications.
This versatile end mill combines a four-flute configuration, multi-edge geometry, and a durable TiAlN coating to boost efficiency, surface finish, and tool life. Its center-cutting design enables plunging cuts and internal pocket work, making it a dependable choice for engineers, shop floors, and hobbyists alike.
- Four-flute design for efficient material removal: The four cutting edges provide fast metal removal and stable cuts, enabling higher throughput and clean, consistent finishes. Improved chip evacuation supports smoother operation and longer tool life.
- Corner radius for smoother cuts and better finishes: The R1 corner radius helps produce smoother tool paths and cleaner edges on profiling and slotting tasks, reducing edge chipping and improving surface quality.
- TiAlN coating for extended wear resistance: The TiAlN coating enhances hardness and heat resistance, delivering longer tool life and maintaining sharpness under demanding general machining workloads.
Designed for reliable performance in general machining, this end mill helps you achieve precise dimensions with fewer passes, reduces downtime from tool changes, and consistently delivers high-quality finishes across a variety of everyday tasks. Its center-cutting capability makes it easy to start cuts anywhere on the workpiece, while the durable coating and geometry support longevity and predictable results.
