Description
The OSG Carbide 3 Flute End Mill with Corner Radius is a 16 mm diameter carbide tool designed for general machining tasks. It features a 3-flute design, a regular-length body, and a TiAlN coating for added durability. With a built-in R3 corner radius and center-cutting capability, it excels at milling, slotting, and profiling in a wide range of materials.
This end mill is aimed at engineers, machinists, and hobbyists who need dependable performance across everyday machining jobs. The TiAlN coating enhances wear resistance, helping the tool maintain sharpness longer and resist heat during demanding cuts, while the sturdy carbide body stands up to recurring use in busy workshop environments.
- TiAlN-coated durability: The TiAlN coating provides exceptional wear resistance and heat tolerance, helping the tool stay sharp longer and extend tool life in challenging materials.
- Corner Radius for smoother cuts: The R3 corner radius delivers cleaner edges and a smoother surface finish while reducing edge chipping and chatter during milling, slotting, and profiling.
- Center-cutting general-purpose design: Regular-length, center-cutting geometry enables plunging, slotting, and contouring with one tool, delivering reliable, versatile performance across a wide range of general machining tasks.
Choosing this end mill supports a smoother workflow: quicker setup, fewer tool changes, and consistent results from project to project. The combination of carbide strength, wear-resistant coating, and the corner radius helps you achieve higher-quality finishes with less rework, making it a dependable choice for everyday machining needs.
