    Octagon Inserts

    Combine an insert holder with carbide inserts (sold separately) to create a milling cutter, also known as indexable milling cutters. They remove metal at least two times faster than comparable high-speed steel milling cutters. When the cutting edges dull, replace the carbide inserts instead of the entire tool.
    Use with an R8 shank arbor (sold separately).

    Face Milling Cutters

    Flat-Surface Cut Style

    With larger diameters than end mills, these cutters remove greater amounts of material to create a smooth, flat channel in the face of a plate, bar, or other wide workpiece. Compared to fly cutters, they’re more rigid, which makes for a better finish. Also known as shell cutters. Cutters with fewer teeth provide better chip clearance for high-volume, high-speed cuts. Those with more teeth provide a finer finish and generate less vibration at high speeds.
    Uncoated—Use uncoated cutters for general purpose milling and short production runs. They stay sharper than coated cutters when used on soft materials like aluminum.
    Titanium Nitride (TiN) Coated—Titanium-nitride (TiN) coated cutters create less friction than uncoated cutters, which means they last longer when run at similar speeds. Use coated cutters 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 cutters.
    Aluminum Titanium Nitride (AlTiN) Coated—Aluminum-titanium-nitride (AlTiN) coated cutters dissipate heat better than other cutters, 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. Use coated cutters 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 cutters.
    High-Speed Steel—High-speed steel cutters are good for general purpose milling in most materials including aluminum brass, bronze, and steel.
    Cobalt Steel—Cobalt steel cutters have better heat and wear resistance than high-speed steel. They can run at higher speeds and provide better performance on hard material such as iron, stainless steel, titanium, and tool steel.

    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.

    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.
    R8 Taper Shank—R8-shank end mills have internal threads on the tapered end for connecting to a drawbar.

    Square Insert

    Create your own versatile milling cutters. These kits include a cutter body, inserts, wrenches, and screws. Also known as indexable end mills, replaceable insert milling cutters remove metal at least two times faster than comparable high-speed steel milling cutters. When the cutting edges dull, replace the carbide inserts instead of the entire tool. The inserts come factory sealed from the manufacturer for maximum traceability.
    Use with an R8 shank arbor (sold separately).
    Kits come with either octagon or square inserts.
    Titanium Diboride (TiB2)-Coated Carbide Insert—Titanium-diboride (TiB2)-coated inserts reduce friction in nonferrous metals and composites, so you can use them without lubrication in material like aluminum, fiberglass, and plastic.
    Titanium Aluminum Nitride (TiAlN)-Coated Carbide Insert—Titanium-aluminum-nitride (TiAlN)-coated inserts dissipate heat better than other inserts, especially at high speeds. At high temperatures, the coating creates a layer of aluminum oxide that transfers heat to the chips, keeping the inserts cool, even when used without lubrication.
    Octagonal Insert—Use octagon inserts for general face milling. With eight cutting edges, they generate smooth cuts.
    Square Insert—Use square inserts to create a 90° corner when shoulder milling.

    Pair these carbide inserts with insert holders to mill the surface of plates and bars. They have a negative rake, so they have cutting edges on both sides—they last longer than comparable positive-rake inserts. As each edge dulls, you can rotate to a fresh one. When all the edges on one side are worn, flip the insert over. Built-in chip breakers prevent long chips from forming, so they won’t block the flow of coolant or damage your tool.
    Inserts sold individually come packed in a clear plastic case to protect cutting edges during shipment. Inserts sold in packs come factory sealed from the manufacturer for maximum traceability.

    Replaceable Carbide-Insert Square End Mill Holders

    Square Cut Style

    Pair carbide inserts with a holder to create end mills that reduce waste and cost in high-volume jobs. When the cutting edges dull, replace the inserts instead of the entire tool. These end mills are also known as indexable shoulder mills. 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 can’t be used for plunge cuts. They have a square cut style for creating square slots, pockets, flat surfaces, and edges.
    When choosing an end mill holder, consider the type of finish you want. The finer the finish, the more inserts you’ll need. More inserts mean tighter spacing, so you can machine at high speeds and remove material quickly while leaving a smooth surface. However, you’ll also need more machine power. Fewer inserts mean a coarser finish—the inserts are spaced apart to help with chip evacuation. A coarse finish is best for roughing applications, light machining, and cutting soft metals such as aluminum.

    Arbor Mount Shown

    with Inserts (Sold

    For arbor mount holders, you’ll need four or more negative-rake-angle inserts. Since the inserts have cutting edges on both sides, they last longer than positive-rake inserts. When all the edges on one side are dull, flip the insert over. These holders have a hole that passes coolant from your machine onto the workpiece, minimizing heat.

    Serrations along the cutting edge act as chip breakers, so these cutters can remove large amounts of material at high speeds without sacrificing tool life. With larger diameters than end mills, they remove greater amounts of material to create a smooth, flat channel in the face of a plate, bar, or other wide workpiece. Compared to fly cutters, they’re more rigid, which makes for a better finish. Also known as shell cutters. With better heat and wear resistance than high-speed steel, these cobalt steel cutters can run at higher speeds and provide better performance on hard material, such as hardened steel, iron, and titanium.
    Uncoated—Use uncoated cutters for general purpose milling and short production runs. They stay sharper than coated cutters when used on soft material, such as aluminum.
    Titanium Nitride (TiN) Coated—Titanium-nitride (TiN) coated cutters create less friction than uncoated cutters, which means they last longer when run at similar speeds. Use coated cutters 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 cutters.
    Aluminum Titanium Nitride (AlTiN) Coated—Aluminum-titanium-nitride (AlTiN) coated cutters dissipate heat better than other cutters, 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. Use coated cutters 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 cutters.
    Coarse Pitch—Coarse pitch cutters create large chips for better performance on soft metals, such as aluminum, brass, and bronze.
    Fine Pitch—Fine pitch cutters last longer than coarse-pitch end mills and produce smaller chips for better performance on hard metals, such as hardened steel, iron, and titanium.

    Holders for Replaceable Carbide-Insert Face Milling Cutters

    Image of ProductInUse. Front orientation. Face Mill Insert Holders. Holders for Replaceable Carbide-Insert Face Milling Cutters.
    Designed for milling the surfaces of plates and bars, cutters consist of multiple carbide inserts and a holder. They help you reduce waste and cost in high-volume jobs—when the cutting edges dull, replace the inserts instead of the entire tool. Cutters have a large mill diameter for making wide, shallow cuts on the face or side of your workpiece. They also have a hole that passes coolant from your machine onto the workpiece, minimizing heat.
    When choosing a holder, consider the grit rating you want. The finer the grit, the more inserts you’ll need. More inserts mean tighter spacing, so you can machine at high speeds and remove material quickly while leaving a smooth surface. However, you’ll also need more machine power.

    Carbide Inserts

    Inserts are locked in place with a screw for a hold that’s strong enough to handle the high speeds of a CNC machine. They have a negative rake, which means they have cutting edges on both sides. They last longer than comparable positive-rake inserts. As each edge dulls, you can rotate to a fresh one. When all the edges on one side are worn, flip the insert over. Built-in chip breakers prevent long chips from forming, so they won’t block the flow of coolant or damage your tool. Inserts sold individually come packed in a clear plastic case to protect cutting edges during shipment. Inserts sold in packs come factory sealed from the manufacturer for maximum traceability.

    Coated inserts are best for demanding, high-speed jobs and hard materials. They’re harder and more wear resistant than uncoated carbide inserts.
    Pair these carbide inserts with a holder to create end mills that reduce waste and cost in high-volume jobs. When all the cutting edges dull, replace the inserts instead of the entire tool.
    Choose inserts with a smaller tip radius to reduce vibration and create smaller chips, so chip evacuation is easier. Choose inserts with a larger tip radius for more aggressive machining—they have a stronger cutting edge, so they remove more material with each pass.
    Inserts sold individually come packed in a clear plastic case to protect cutting edges during shipment. Inserts sold in packs come factory sealed from the manufacturer for maximum traceability.
    Use uncoated inserts for general purpose milling and short production runs.
    Negative Rake Angle—Negative-rake angle inserts have cutting edges on both sides, so they last longer than positive-rake inserts. When all the edges on one side are dull, flip the insert over.
