OSG Carbide 3 Flute End Mill Corner Radius DLC Coated - For Aluminium - 25mm x R3

The OSG Carbide 3 Flute End Mill with a corner radius and DLC coating is a precision machining tool designed specifically for aluminum. With three flutes and a defined corner radius, it balances fast, efficient material removal with stable, accurate finishes—making it a dependable choice for professionals and serious hobbyists alike.

Engineered for aluminum workpieces, this DLC-coated end mill delivers extended tool life and consistent results in demanding milling operations. The 25 mm diameter with a 3 mm corner radius supports clean radii, smooth pocketing, and reliable edge quality across a range of aluminum alloys.

• DLC coating for longer life: The Diamond-Like Carbon coating reduces wear and resist built-up edge, helping edges stay sharp longer so you can run longer between tool changes and maintain consistent finishes on aluminum.
• Three-flute geometry for stability and efficiency: The 3-flute design provides a good balance between chip evacuation, rigidity, and a smooth cut in aluminum, reducing chatter and improving surface finish.
• 25 mm diameter with 3 mm corner radius: The larger diameter and defined corner radius create clean radii in pockets and profiles, reduce burrs, and preserve part geometry while delivering reliable cutting performance on aluminum.

In practical terms, this end mill helps you finish jobs faster, with fewer passes, and with consistent results across runs. The DLC coating reduces downtime for tool changes, while the three-flute design handles aluminum's dynamics and allows for robust engagement per pass, boosting productivity. The defined corner radius gives your parts precise radii and sharp corners without sacrificing tool life, making it suitable for both production and prototyping environments.
