    8 Cutting Edges

    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.
    Positive Rake Angle—Positive-rake angle inserts are designed to reduce vibration and keep thin workpieces from bending. They have cutting edges on only one side.
    Chip Breakers—Inserts with chip breakers prevent long chips from forming, so they won’t block the flow of coolant or damage your tool.

    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.

    Insert Case

    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.
    Inserts have a positive rake angle, which means the cutting edge is angled to reduce vibration and prevent thin workpieces from bending. For a longer life, each insert has two cutting edges—rotate the insert when the first side wears down. 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 in a clear plastic case to prevent damage during shipping. Inserts sold in packs come factory sealed from the manufacturer, which makes them easy to trace.

    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.
    Inserts have a positive rake angle, which means the cutting edge is angled to reduce vibration and prevent thin workpieces from bending. For a longer life, each insert has two cutting edges—rotate the insert when the first side wears down. They have chip breakers to stop long chips from forming, so they won’t block the flow of coolant or damage your tool.

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.
