Description
The OSG Carbide 4 Flute End Mill Square, 20 mm diameter, is a high-performance cutting tool designed for general machining tasks. Made from solid carbide and featuring a TiAlN coating, this square-end mill is tailored for reliable milling, slotting, and profiling across a wide range of materials. Its center-cutting geometry enables plunge cutting, making it versatile for both pocketing and through-slots.
With a long-length design, it reaches deep into pockets, channels, and hard-to-reach features while maintaining rigidity and consistent cutting performance. This makes it a dependable choice for engineers, machinists, and hobbyists who demand accuracy, repeatable results, and long tool life in everyday milling jobs.
- Long-length design for deep reach: Access deep pockets, slots, and challenging features without repositioning or changing tools, while preserving cutting efficiency and rigidity.
- TiAlN coating for extended tool life: The TiAlN coating reduces wear and heat buildup, helping the tool last longer in demanding materials and high-speed milling.
- Four-flute, center-cutting geometry: Efficient material removal with smooth finishes, reliable plunging capability, and stable performance in profiling and slotting tasks.
This end mill helps you streamline setups, reduce tool changes, and deliver precise, repeatable results—from roughing to finishing. Its combination of wear resistance and extended reach supports faster cycle times, cleaner finishes, and dependable performance across a broad range of general machining applications.
