End mills and indexable inserts are the cutting tools for milling machines, CNC machining centers and lathes. This section covers solid carbide and HSS or cobalt end mills in 2, 3 and 4 flute designs, square end, ball nose and corner radius profiles, roughing end mills, chamfer mills, and carbide inserts for turning, facing, grooving and milling. Coatings such as TiN, TiAlN and AlTiN extend tool life in specific materials.

What to check before you order

• Flute count. Two and three flute end mills clear chips well in aluminum and other soft metals. Four or more flutes give a better finish and more strength in steel.
• Tool material. Carbide runs faster in rigid CNC setups. HSS and cobalt are more forgiving on manual machines.
• Coating. Some coatings help in steel but are a poor match for aluminum. Check the maker's material recommendations.
• Insert geometry. Match the insert shape, size, relief angle, nose radius and chipbreaker to your holder and material. The ISO insert code spells these out.
• Length of cut. Use the shortest tool that reaches the feature to reduce chatter.

Common questions

How many flutes should an end mill have for aluminum?

Two or three flutes are a common choice, because the larger flute space clears soft chips without packing.
