1/8" CNC Tapered Ball Nose Bit – 1/4" Shank

1/8" Tapered Ball Nose
Tungsten Carbide • Nano Blue Coated

Overview
Built for detailed 3D carving, contouring, and finishing passes where strength and surface quality matter. The tapered profile adds rigidity over straight ball nose tools to reduce chatter and deflection, while the ball nose tip produces smooth contours. Nano Blue coating helps reduce heat and wear during long finishing passes.

Best For

• 3D relief carving
• Contours and organic shapes
• Fine detail work
• Finishing passes

Why Choose It

• Tapered profile improves rigidity
• Ball nose tip creates smooth 3D surfaces
• Reduces chatter vs. straight ball nose cutters
• Great for detail and finishing work
