Dolphin 55 HRC 2 Flute Ball Solid Carbide End Mill

The Dolphin 55 HRC 2 Flute Ball Solid Carbide End Mill is a specialized cutting tool designed for high-performance milling applications, particularly suited for machining hardened materials. Here are the key details and features of this specific end mill:

1. Material and Hardness:

   • Material: Solid carbide
   • Hardness: 55 HRC (Rockwell Hardness C scale)

   The end mill is made from solid carbide, which provides excellent hardness and wear resistance, ideal for machining tough and hardened materials up to 55 HRC. This hardness rating indicates the end mill's capability to cut through or shape hard materials effectively.

2. Flute Design:

   • Flute Type: 2 Flute (Two cutting edges)
   • Ball End: The end mill has a ball-shaped cutting end.

   The 2 flute design means the end mill has two cutting edges, which can provide better chip evacuation and smoother cutting action compared to higher flute counts. The ball end geometry allows for contouring, profiling, and 3D milling operations, especially useful for creating curved or sculpted surfaces.

3. Applications:

   • Hardened Materials: Suitable for milling hardened materials up to 55 HRC, such as hardened steels, tool steels, stainless steels, and other alloys.
   • Precision Machining: Ideal for precision machining tasks, including mold making, die sinking, and high-accuracy surface finishing.
   • Profile Machining: Effective for profile milling, contouring, and finishing applications that require smooth surface finishes.

4. Performance and Benefits:

   • High Hardness Capability: Can efficiently machine materials with a hardness rating of up to 55 HRC, maintaining cutting edge integrity and tool life.
   • Precision and Accuracy: Provides precise and accurate results, especially in intricate milling operations.
   • Chip Evacuation: The 2 flute design aids in effective chip removal, reducing the risk of chip buildup and improving machining efficiency.
   • Versatility: Suitable for a range of applications from roughing to finishing, offering versatility in machining tasks.

5. Usage Recommendations:

   • Cutting Parameters: Optimize cutting parameters (such as spindle speed, feed rate, and depth of cut) based on the material being machined and the specific application.
   • Tool Holding: Ensure secure tool holding using suitable tool holders to minimize vibration and ensure dimensional accuracy.
   • Coolant/Lubrication: Use appropriate cutting fluids or lubricants to improve tool life and surface finish, especially when machining hardened materials.
