Description
The OSG Carbide 3 Flute End Mill with Corner Radius is a versatile center-cutting tool designed for general machining tasks. With a 4 mm diameter and a 0.25 mm corner radius, it handles milling, slotting, and profiling with smooth edges and consistent results.
- Corner Radius for Smoother Cuts: The 0.25 mm radius reduces edge chipping and delivers smoother finishes in corners and profiles, improving stability and overall surface quality.
- TiAlN-Coated for Longer Tool Life: The TiAlN coating enhances hardness and wear resistance, helping the tool maintain sharpness and perform reliably under demanding cutting conditions.
- Three-Flute, Center-Cutting Design for General Use: The three-flute geometry provides a strong cut with efficient chip evacuation, while center-cutting capability enables plunge cuts for versatile milling from slots to pockets.
This end mill is crafted to deliver consistent, high-quality results across a broad range of general milling tasks. The combination of a rigid three-flute geometry, durable TiAlN coating, and precise corner radius helps you achieve cleaner finishes, reduce rework, and extend tool life, supporting faster project completion and dependable performance in everyday machining.
