Carbide Ball Nose Lollipop End Mill for Aluminum 3 Flute High Speed CNC Milling Cutter Tungsten Steel Long Neck Design for 3D Contouring

Introduction:

Our Carbide Ball Nose Lollipop End Mill is a specialized cutting tool designed for high-precision 3D contouring and finishing in aluminum and other non-ferrous materials. Featuring a unique long neck "lollipop" design crafted from ultra-fine grain tungsten carbide, this end mill delivers exceptional performance in high-speed CNC machining applications where deep cavities and complex geometries are required.

The 3-flute configuration and optimized ball nose geometry ensure superior surface finishes while maintaining aggressive material removal rates, making it ideal for aerospace, automotive, and mold-making industries.

Features:

1. Advanced Tool Geometry

• True ball nose design (R0.005mm tolerance) for precision 3D profiling

• Long neck "lollipop" reach (up to 10×D) for deep cavity machining

• 3-flute asymmetric design reduces harmonic vibration and chatter

2. Premium Material Construction

• Japanese-grade tungsten carbide substrate (0.4μm grain size)

• Nano-composite coating (AlTiN/TiSiN options) for extreme heat resistance

• Reinforced core structure prevents deflection during deep cuts

3. Performance Advantages

✓ 30% higher feed rates than standard ball nose end mills
✓ Mirror surface finishes (Ra 0.2μm achievable)
✓ 4× longer tool life compared to HSS alternatives
✓ Reduced cycle times through optimized chip evacuation

4. Customization Options

• Diameter range: 1mm-20mm (0.039"-0.787")

• Neck lengths: Standard (5×D), Long (8×D), Extra-Long (10×D)

• Shank configurations: Straight, Weldon flat, HSK compatible

• Special geometries: Custom corner radii, variable helix options

Advantages:

For CNC Programmers:

• Achieve complex 3D contours in single passes

• Maintain tight tolerances (±0.01mm) in deep pockets

• Optimize tool paths with our free speed/feed calculator

For Production Managers:

• Reduce tool inventory with multi-purpose performance

• Lower cost per part through extended tool life

• Minimize machine downtime with reliable cutting performance
