    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.

    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.

    Aluminum Titanium Chromium Nitride (AlTiCrN)-Coated Carbide—Coated inserts are used for demanding, high-speed jobs in hard material. They’re harder and more wear resistant than uncoated carbide inserts.
    Uncoated Carbide—Uncoated inserts are best for general purpose milling and short production runs.

    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.

    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.
