OSG Carbide 3 Flute End Mill Corner Radius - For Aluminium - 4mm x R1

The OSG Carbide 3 Flute End Mill with corner radius is a versatile tool designed for aluminum machining. Featuring three flutes and a corner radius, it excels in milling, profiling, and slotting with reliable material removal and stable cuts. This end mill is a trusted choice for machinists working with aluminum, delivering consistent, high-performance results where precision and efficiency matter.

With a 4 mm diameter and a 1 mm corner radius (R1), this tool produces crisp edges and repeatable profiles, making it ideal for both production runs and detailed prototype work.

• Three-flute geometry for efficient aluminum removal: The three flutes balance rigidity with chip evacuation, enabling smoother cuts, higher feed rates, and reduced chatter when machining aluminum.
• Corner radius for precise profiles and edge quality: The R1 radius helps produce sharp, repeatable corners and improves surface finish during profiling and slotting, reducing the need for rework.
• Carbide construction for durability and consistent performance: Solid carbide provides wear resistance and long tool life, delivering stable diameter and reliable results across multiple runs.

By combining a durable carbide body, a precisely engineered corner radius, and a geometry optimized for aluminum, this end mill helps you cut faster, reduce finishing passes, and achieve repeatable, high-quality surfaces across production, prototyping, and maintenance tasks.
