AMANA Ball Nose Spiral Bit

Features

• Solid carbide ball nose spiral bits for smooth 3D contouring, relief carving and mold work
• Rounded tip geometry leaves smooth, stepless surfaces on curved and sculpted profiles
• 9 variants spanning 0.5mm to 38mm cutting diameter with ball radii from 0.25mm to 3mm for fine detail through large-area roughing

How to Use

Select bit radius based on the smallest detail in your 3D toolpath, then run a roughing pass with a larger-radius bit before finishing with a smaller radius for detail. Use consistent stepover in CAM software (typically 10-20% of tool diameter) for a smooth finished surface, and reduce feed rate on the smallest diameters to prevent bit deflection or breakage.
