2 Flute Micro Diameter Ball Nose End Mills With 30 Degrees Helix Angle

Product Description:

Ballnose End Mills are precision cutting tools with a hemispherical tip designed for 3D contouring, surface finishing, and complex geometrical machining. Their rounded tip allows smooth engagement in all directions, reducing tool marks and enabling excellent surface finishes in mold making, die sinking, and aerospace part manufacturing.

Advanced grinding technology to achieve ultra-high blade
diameter and shank diameter accuracy, suitable for precision molds and parts processing;
High wear-resistant coating, arc transition structure to ensure high breakage resistance, to achieve Long-term cutting of hardened steel.

Features:

1. Ideal for 3D Contour Machining

The spherical cutting tip makes ballnose end mills perfect for machining complex geometries, curved surfaces, and mold cavities with precision.

2. Superior Surface Finish

The smooth, rounded tip reduces tool marks and produces high-quality surface finishes, especially in finishing operations.

3. Flexible Cutting Approach

Ballnose tools allow multi-directional machining, making them well-suited for 3-axis and 5-axis simultaneous machining applications.

4. Versatility for Roughing and Finishing

With options in flute number and geometry, the same tool type can be used for both roughing and precision finishing, reducing tool change times.

5. Suitable for a Wide Range of Materials

Ballnose end mills are compatible with various materials, including hardened steel, stainless steel, aluminum, copper, graphite, and composites.

6. High Wear Resistance with Coatings

Advanced coatings like TiAlN, AlTiN, and DLC enhance heat resistance and tool life, making them suitable for dry or high-speed machining.

7. High Rigidity for Stable Cutting

Constructed from solid carbide or coated HSS, ballnose end mills offer excellent rigidity and vibration resistance during cutting.

Applications:

1. Mold and Die Making
Ballnose end mills are widely used in the mold industry for machining 3D cavities, curved surfaces, and intricate contours in steel or graphite molds. Ideal for both roughing and finishing operations.

2. 3D Surface Profiling
Perfect for sculpted surfaces and freeform shapes in industries such as automotive design, aerospace components, and product prototypes. Enables smooth and accurate surface generation.

3. Aerospace Component Machining
Used for finishing turbine blades, impellers, and structural parts with complex geometries. The ball tip allows continuous engagement with curved surfaces and minimizes tool marks.

4. Engraving and Fine Detail Work
Small-diameter ballnose mills are commonly used for engraving, relief carving, and small radius detail cutting, particularly in CNC routers and engraving machines.

5. Medical Implant Manufacturing
Used in machining contoured surfaces of implants (e.g., hip joints, dental parts) that require precision and smooth finishes on titanium or cobalt-chrome alloys.

6. Graphite Electrode Machining
Graphite-compatible ballnose tools (often with DLC coating) are used to produce fine, wear-resistant details in EDM electrodes for precision die sinking.

7. Hard Material Finishing
High-speed finishing of hardened steels (HRC 50–65) using coated carbide ballnose end mills for applications in die finishing and precision tooling.

8. Wood and Composite Machining
In CNC woodworking, ballnose tools are used to create decorative curves, 3D textures, and artistic reliefs on materials like MDF, hardwood, or composite panels.
