How to choose
- Flutes: 2-flute end mills clear chips well in aluminum and for slotting; 4-flute end mills give better finish and strength in steel.
- Material: HSS for general and manual milling; cobalt for tougher steels and stainless; solid carbide for higher speeds, CNC work and longer tool life.
- Shape: square end for flat bottoms and shoulders; ball end for 3D contours and fillets; corner rounding for edge radii; roughing for fast stock removal.
- Single vs. double end: double-end end mills give two cutting ends per tool for lower cost per edge.
- Size: choose the largest diameter and shortest length that fit the feature to limit chatter and deflection.
