High-Speed Steel Square End Mills
4 Flute
Use these end mills for general purpose milling in most material, such as aluminum, brass, bronze, iron, and steel. They have a square end for milling square slots, pockets, and edges.
End mills with fewer flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts; end mills with more flutes provide a finer finish and operate with less vibration when run at high speeds.
Use uncoated end mills for general purpose milling and short production runs.
Center-cutting end mills allow plunge cuts into a surface.
