Dolphin 4 Flute High Performance Solid Carbide Ball Nose End Mill 55 HRC

A Dolphin 4 Flute High Performance Solid Carbide Ball Nose End Mill with a hardness of 55 HRC is a specialized cutting tool designed for demanding milling applications, particularly those involving hard materials. Here's a breakdown of its features: 1. **Dolphin Design**: The term "dolphin" likely refers to the specific flute geometry of the end mill. This design feature may enhance chip evacuation, cutting performance, or tool longevity. Without specific details, it's difficult to ascertain the exact design elements associated with the "dolphin" designation. 2. **4 Flute**: This indicates that the end mill has four cutting edges or flutes. Four-flute end mills are often used for applications requiring higher feed rates and increased chip evacuation compared to two-flute designs. They can provide better stability during cutting operations. 3. **High Performance**: This suggests that the end mill is engineered for high-speed and high-efficiency machining applications. High-performance end mills typically feature advanced geometries, coatings, and materials to improve cutting performance, tool life, and surface finish. 4. **Solid Carbide**: The end mill is made from solid carbide, a high-performance material known for its hardness, wear resistance, and ability to maintain sharp cutting edges. Solid carbide end mills are suitable for machining a wide range of materials, including metals, plastics, and composites. 5. **Ball Nose**: The "ball nose" feature indicates that the end mill has a rounded end, resembling a ball. This design is particularly useful for contouring, profiling, and 3D machining operations, allowing for smooth curves and precise geometries in the workpiece. 6. **55 HRC**: This specification denotes the hardness of the end mill material. HRC stands for Rockwell Hardness Scale C, which measures the hardness of materials, particularly metals. A hardness of 55 HRC indicates that the end mill is specifically suited for machining materials with a similar or lower hardness, such as hardened steels, stainless steels, and other tough alloys. Overall, a Dolphin 4 Flute High Performance Solid Carbide Ball Nose End Mill with a hardness of 55 HRC is designed to deliver exceptional cutting performance, tool life, and surface finish in challenging milling applications, particularly those involving hard materials.
