High-Speed Steel Square End Mills



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. Use titanium-nitride (TiN) coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. They’re more wear resistant than uncoated end mills, which means they last longer when run at similar speeds.
Center-cutting end mills allow plunge cuts into a surface. Noncenter-cutting end mills are for operations where the peripheral teeth do most of the work, such as shoulder milling, contouring, and finishing. They cannot be used for plunge cuts.

High-Speed Steel Square End Mills for Aluminum, Brass, and Bronze

With a higher helix angle than standard high-speed steel end mills, these clear more chips and generate less heat, making them good for milling soft material, such as aluminum, brass and bronze. They are center cutting for making plunge cuts into surfaces and have a square-end cut style for milling square slots, pockets, and edges.
End mills with two flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts.
Use uncoated end mills for general purpose milling and short production runs.

High-Speed Steel Square End Mills with Two Milling Ends


When one end wears out, switch to the opposite end for two times the life of a standard high-speed steel end mill. Made of high-speed steel, these end mills are for general purpose milling in most material, such as aluminum, brass, bronze, iron, and steel. Their square ends make them good for milling square slots, pockets, and edges. All are center cutting, allowing plunge cuts into a surface.
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.

High-Speed Steel Ball End Mills


Use these end mills for general purpose milling in most material, such as aluminum, brass, bronze, iron, and steel. They have a ball end for milling rounded slots, slopes, and contours. All are center cutting, allowing plunge cuts into a surface.
End mills with two flutes provide better chip clearance for high-volume, high-speed plunge, slotting, and roughing cuts. Use uncoated end mills for general purpose milling and short production runs. Use titanium-nitride (TiN) coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. They’re more wear resistant than uncoated end mills, which means they last longer when run at similar speeds.
