    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.

    End Mill with Coolant Hole

    Variable spacing between the flutes reduces vibration, allowing these end mills to provide fast cuts, smooth finishes, and long tool life on hard materials. Often used for slotting and pocketing cuts in mold and die making, these end mills have a 90° profile and rounded corners, which reduce flute breakage and chipping. Also known as corner radius end mills.
    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.
    A titanium aluminum nitride (TiAlN) or aluminum titanium nitride (AlTiN) coating allows them to 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. This makes these good for aggressive machining while roughing or making interrupted cuts.
    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.
    End Mills for Extreme Ramping and Plunging—End mills for extreme ramping and plunging are good for both angled and vertical cutting. Choose these end mills so you can have one tool for ramping and plunging. They can enter the material at up to a 45° ramping angle to reach your desired depth faster than standard end mills, which typically machine at 1° to 3° angles. These end mills also evacuate chips faster and last longer.
    End Mills for Coolant Holes—End mills with coolant holes allow coolant to run through the tool and directly to the cutting edge to help flush out chips. Use them in CNC machines with coolant-through technology.
    Center Cutting—Center-cutting end mills allow plunge cuts into a surface.
    Noncenter Cutting—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.
