BB Ball Nose End Mill – 3 & 4 Flute Solid Carbide (BF2055 / BB2055)

Precision-ground solid carbide ball nose end mills optimized for semi-finishing and finishing of complex 3D contours and mold cavities. Choose between 3-flute and 4-flute geometry based on your workpiece material.

Which Series Should I Choose?

Series	Flutes	Best For	Advantage
BF2055	3 Flute	Aluminum, non-ferrous metals	Larger chip clearance, prevents built-up edge, excellent surface finish on Al
BB2055	4 Flute	Steel, stainless steel, hardened steel	Higher rigidity, better surface finish on ferrous materials
