Carbide Tapered Ball Nose Ø0.5mm

Ideal for 3D carving and surface finishing for smooth, detailed contouring across a range of materials. The tapered shaft adds strength and reduces deflection, making it perfect for finishing passes on wood, plastics, foams, and soft metals. A reliable choice for sign-makers, sculptors, and CNC professionals needing clean, consistent results in medium-to-fine detail work.

Shank: 6mm | Cut Length: 20.5mm | Cut Radius: Ø0.25mm

Key Features:

• Ball Radius: 0.25mm – extremely small, ideal for ultra-fine details and tight corners
• Tapered Shaft: The shaft gradually narrows from the shank to the ball tip, which increases rigidity and reduces vibration
  
• Material: Made from solid carbide, offering excellent wear resistance and cutting edge sharpness
  
• Flute Count: 2 Flute for wood and plastics
  

Applications:

• 3D carving and relief engraving on wood, plastic, wax, and soft metals
  
• Creating fine textures, engraved patterns, and delicate curves
  
• Ideal for finishing passes in 3D modelling/CAD-CAM workflows, such as:
  
  • Sculptures
    
  • Jewellery moulds
    
  • Topographic maps
    
  • Lithophanes

Material Suitability:

• Hardwood and softwood
  
• MDF and plywood
  
• Plastics (e.g., acrylic, polycarbonate)
  
• Foam board and modelling materials
  
• Soft metals like aluminium and brass (with proper settings)
  

Advantages:

• High precision for fine detail and sharp resolution in 3D work
  
• Tapered design reduces breakage and vibration
  
• Allows deeper reach than straight ball nose bits without compromising accuracy
  
• Produces smooth surface finishes on 3D contours

Limitations:

• Very slow material removal rate due to small radius – best suited for final detail passes
  
• Fragile tip – can break if pushed too hard or used on hard materials
  
• Requires high spindle speed and precise feed rates for optimal results
