    6 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.
    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.

    Shave shallow layers of material off your workpiece to create a smooth even finish. These fly cutters hold a lathe tool (sold separately) and run on your milling machine. Compared to end mills, these make a wider cut per pass. They also generate less heat, so you can run them at higher speeds. In the long run, these cutters will save you the cost of replacing entire end mills once they dull—you can either sharpen your worn lathe tool or just replace that one part.

    Dovetail Cut Style

    Use these versatile end mills for milling in most material, including aluminum, brass, bronze, iron, and steel. They create dovetail slots for connecting two components with a sliding fit.
    Uncoated High-Speed Steel—Uncoated end mills are for general purpose milling and short production runs. They stay sharper than coated end mills when used on soft materials like aluminum, leaving a better finish.

The coating reduces friction and vibration as they’re used, making them more wear resistant than uncoated end mills.
    Titanium Carbon Nitride (TiCN)-Coated High-Speed Steel—Titanium carbon nitride (TiCN)-coated end mills have a hard, smooth finish that resists chipping and wear and prevents material from accumulating on the cutting edge. They’re especially good for use in aluminum. Use coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. The coating reduces friction and vibration as they’re used, making them more wear resistant than uncoated end mills.
    Aluminum Titanium Nitride (ALTiN)-Coated High-Speed Steel— 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. This makes these good for aggressive machining while roughing or making interrupted cuts. Use coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs. The coating reduces friction and vibration as they’re used, making them more wear resistant than uncoated end mills.

    Made of carbide-tipped high-speed steel, these end mills provide a sharper, harder edge at high temperatures than plain high-speed steel. Because they aren’t as brittle as solid carbide, they can be used in less rigid setups, such as manual milling machines. The teeth are angled in two directions so you can make top and bottom chamfers without having to flip the workpiece.

    Use these tools with low-horsepower, manual milling machines. They have clamps for holding inserts that do not have a mounting hole. Replaceable carbide-insert end mills reduce waste and cost in high-volume jobs—when the cutting edges dull, replace the carbide inserts instead of the entire tool. End mills have a square cut style for milling square slots, pockets, and edges. All are noncenter-cutting for operations where the sides of the teeth do most of the work, such as shoulder milling, contouring, and finishing. They cannot be used for plunge cuts.

    Get speed and longevity when cutting keyseats with these carbide end mills that have staggered teeth. The alternating right- and left-hand tooth style removes more material at high speeds than straight-tooth keyseat cutters. They mill precise notches in rotary shafts to fit machine keys and can also be used for slot milling. 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.
    Uncoated Carbide—Use uncoated end mills for general purpose milling and short production runs. They will stay sharper than coated end mills and leave a better finish on soft materials like aluminum.
    Aluminum Titanium Nitride (AlTiN)-Coated Carbide—Use aluminum titanium nitride (AlTiN)-coated end mills for demanding, high-speed jobs in hard material as well as for longer production runs.

    Keyseat Cut Style

    Made of solid carbide, these cutters 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. Use them to mill precise notches in rotary shafts to fit machine keys. They can also be used for slot milling.
