Description
The OSG Carbide 4-Flute End Mill with Corner Radius is a versatile, general-purpose cutting tool designed for a wide range of machining tasks. With a 12 mm diameter and a 1 mm corner radius, this 4-flute carbide end mill delivers precise milling, slotting, and profiling across common workholding setups. TiAlN coating enhances wear resistance and allows you to push speeds a bit higher while maintaining tool life. Its regular length and center-cutting capability make it suitable for both plunging and planar milling in demanding general applications.
- Corner Radius for Smoother Cuts and Improved Finish: The 1 mm radius softens entry and exit cuts, reduces chatter, and yields cleaner radii on pockets and shoulders, helping surfaces look and feel better with less post-processing.
- Four-Flute Design for Efficient Material Removal: A rigid, four-flute geometry enables higher feed rates and more consistent chip evacuation, delivering faster milling, cleaner slots, and reliable performance on a variety of materials.
- TiAlN Coating for Durability and Longer Tool Life: The TiAlN coating boosts hardness and wear resistance, helping the end mill hold sharpness longer under tougher cutting conditions and reducing downtime for tool changes.
This end mill is a dependable choice for engineers, machinists, and hobbyists who require predictable, repeatable results in general machining. The combination of a precise corner radius, robust four-flute geometry, and durable TiAlN coating supports steady workflows, reduced rework, and improved overall productivity across milling, slotting, and profiling tasks.
