    High-Speed Steel Square End Mills

    2 Flutes

    Image of Product. Front orientation. End Mills. High-Speed Steel Square End Mills, 4 Flutes.

    4 Flutes

    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.
    Uncoated High-Speed Steel—Use uncoated end mills for general purpose milling and short production runs.
    Titanium Nitride (TiN)-Coated High-Speed Steel—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—Center-cutting end mills allow plunge cuts into a surface.

    Fast-Cut Carbide Square End Mills with Chamfer Corner

    Image of Product. Front orientation. End Mills. Fast-Cut Carbide Square End Mills with Chamfer Corner, 4 Flutes.

    4 Flutes

    A 45° corner chamfer improves cutting edge strength, so these end mills last longer than standard square end mills when milling hard material; however they do not create as sharp of a corner. Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life on hard materials. They have a square end for milling square-bottomed slots, pockets, and edges. All are center cutting, allowing plunge cuts into a surface.
    Made of solid carbide, these end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking.
    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.
    Aluminum Titanium Nitride (AlTiN)-Coated Carbide—Titanium aluminum nitride (TiAlN)- and aluminum titanium nitride (AlTiN)-coated end mills dissipate heat better than other end mills, especially at high speeds. At high temperatures, the coating creates a layer of aluminum oxide that transfers heat to the chips, keeping the tool cool, even when used without lubrication.

    Cobalt Steel Square End Mills with Two Milling Ends

    Image of Product. Front orientation. End Mills. Cobalt Steel Square End Mills with Two Milling Ends, 4 Flutes.

    4 Flutes

    When one end wears out, switch to the opposite end for two times the life of a standard cobalt steel end mill. With better heat and wear resistance than high-speed steel, these cobalt steel end mills can run at higher speeds and provide better performance on hard material, such as iron, hardened steel, titanium, and tool steel. Their square ends make them good for milling square slots, pockets, and edges. All are center cutting, allowing plunge cuts into a surface.
    4 Flutes—End mills with four flutes provide a finer finish and operate with less vibration when run at high speeds.

    Roughing High-Speed Steel Square End Mills

    Image of Product. Front orientation. End Mills. Roughing High-Speed Steel Square End Mills, 4 Flutes.

    4 Flutes

    Serrations along the cutting edge act as chip breakers, so these end mills can remove large amounts of material at high speeds. They are high-speed steel for general purpose milling in most material, such as aluminum, brass, bronze, iron, and steel. Their square end makes them good for milling square slots 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.
