Description
The OSG Carbide End Mill is a 4 mm diameter, two-flute tool with a corner radius of 0.25 mm, designed for general machining. Its regular-length, center-cutting construction makes it capable of milling, slotting, and profiling with reliable control across a wide range of materials. The TiAlN coating boosts wear resistance and tool life, helping you push through tougher workpieces without frequent tool changes.
With the corner radius for smoother cuts and improved surface finishes, this end mill provides versatility for everyday manufacturing, repair, and prototyping tasks. The center-cutting geometry supports plunging and precise slotting, making it a dependable choice for both beginners and seasoned machinists.
- Two-flute carbide design for efficient material removal: Balances rigidity with chip clearance to deliver steady cutting and faster material removal on general machining tasks.
- TiAlN coating for longer tool life: Enhances wear resistance and heat tolerance to extend cutting life and maintain sharpness between re-sharpenings.
- 0.25 mm corner radius with center-cutting versatility: The corner radius enables smoother, higher-quality finishes on profiles and slots, while center-cutting allows plunging and flexible milling directions.
Together, these features translate into reliable, repeatable results across general milling tasks. The tool’s durability reduces downtime from tool changes, while the combination of corner radius and center-cutting geometry delivers smoother finishes and consistent depths of cut, improving overall workflow and part quality. Whether you’re engineering, maintaining, or prototyping, this end mill provides a dependable, long-lasting option for everyday milling, slotting, and profiling tasks.
