Description
The OSG Carbide 3 Flute End Mill Square with TiAlN coating is a versatile, general‑purpose cutting tool designed for a wide range of machining tasks. With an 8 mm diameter and a regular length, it’s built for center cutting, making it ideal for milling, slotting, and profiling in everyday production and hobbyist projects alike. The TiAlN coating helps the tool resist wear and maintain sharpness, so you can trust consistent performance through longer runs and tougher materials.
- TiAlN-coated carbide for longer tool life: The hard TiAlN coating reduces wear and enables higher cutting temperatures, helping the end mill stay sharper longer and reducing tool changes in demanding jobs.
- Three-flute design for efficient material removal: The 3-flute geometry strikes a balance between fast material removal and good surface finish, boosting productivity on general milling tasks while maintaining control and stability.
- Regular length, center-cutting square end for versatile use: Center-cutting capability and a square end support simultaneous milling, slotting, and profiling in a single tool without swapping setups.
This end mill delivers reliable, consistent results across a broad spectrum of everyday machining needs. By combining durable carbide with a protective TiAlN coating, it supports steady throughput, reduces downtime due to wear, and helps you achieve smooth finishes and precise dimensions with fewer tool changes.
