    Combine a holder with carbide inserts 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).
    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.
    Titanium Diboride (TiB2)-Coated Carbide—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 Carbon Nitride (TiCN)-Coated Carbide—Titanium-carbon-nitride (TiCN) coated inserts 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.
    Titanium Aluminum Nitride (TiAlN)-Coated Carbide—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.
    Octagon—Use octagon inserts for general face milling. With eight cutting edges, they generate smooth cuts.
    Round—Use round inserts for roughing and heavy cuts. Their shape makes them stronger than octagon and square inserts.
    Square—Use square inserts to create a 90° corner when shoulder milling.

    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.

    Replaceable Carbide-Insert Square End Mill Holders

    Image of ProductInUse. Square Cut Style. Front orientation. End Mill Insert Holders. 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.

    Shank Mount Shown

    with Inserts (Sold

    Separately)

    For shank mount holders, you’ll need two or three positive-rake-angle inserts. Both the holders and inserts are designed to reduce vibration and keep thin workpieces from bending. However, the inserts have cutting edges only on one side. Chip breakers on the inserts keep long chips from forming, so they don't damage your tooling or restrict coolant flow.

    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.

    Fasten one insert to the center of these end mills and three more to the sides, and you can use them for drilling, shoulder milling, contouring, and finishing. When the cutting edges dull, switch out the inserts instead of replacing the whole tool. These end mills help you reduce waste and costs in high-volume jobs. The inserts are locked in place with a screw for a hold that’s strong enough to handle the high speeds of a CNC machine.

    Cut down on waste and cost during high-volume jobs. These end mills consist of a holder and a carbide insert, so you can swap in a fresh cutting edge without replacing the whole tool. The 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’re held at an angle, so you can create chamfers, bevels, and other angled cuts. You can also use them like a face mill for flat surface cutting.

    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.

    Designed to reduce waste and costs during high-volume jobs, these counterbores consist of both an insert and a holder. When the cutting edges dull, you can replace the insert rather than the entire tool. The inserts are locked in place with a screw for a hold that’s strong enough to handle the high speeds of a CNC machine. These counterbores create flat-bottomed holes that allow socket head screws to sit flush with the surface of your material.

    Individual Carbide

    Insert Case

    Inserts have a positive rake, which means the cutting edge is angled to reduce vibration and prevent thin workpieces from bending. For longer life, each insert has three cutting edges—when one edge dulls, rotate to the next one. They have chip breakers to stop 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.
