    Collet Set

    Keep a set of R8 collets on hand to hold cutting tools in the spindle of your Bridgeport or other milling machine. These collets thread onto your machine’s drawbar, pulling them into the spindle so they can clamp tightly around your bit.
    The lower the runout, the higher the accuracy and the longer the tool life.
    0.0008" Total Indicated Runout (TIR) Accuracy—An accuracy of 0.0008" works well for roughing and heavy material removal, where tight tolerances aren't critical.

    Collet Set

    Keep a set of ER collets on hand to hold cutting tools for milling, drilling, and routing. They’re the most versatile and widely used type of collet. Spring slots clamp evenly around the shank to minimize runout for clean, accurate cuts and long tool life. The slots flex to grip slightly undersized shanks too, so you don't need an exact match for each cutting tool in your lineup. You can also use these collets in ER collet fixtures and custom setups to keep small round parts centered.
    52100 Alloy Steel—Hardened 52100 alloy steel collets are made from the same tough material used to make bearings. They’re more wear-resistant than basic spring steel collets but will wear faster than hardened chrome-moly steel collets if you change bits frequently.
    Chrome-Moly Steel—Hardened chrome-moly steel collets are more wear-resistant than hardened 52100 alloy steel collets. They hold their shape better over time and have lower runout, even with frequent bit changes. Often used for high-volume production runs, they stand up to high-speed, high-force machining in any material.

    TG Collet Sets

    Image of Product. Front orientation. Milling Machine Collets. TG Collet Sets.
    Keep a set of TG collets on hand to clamp cutting tools for rough milling and drilling. These collets have a steep taper angle for a tighter, more stable grip than ER collets. This design gives them the strength to handle large tools and aggressive cuts. However, their grip range is smaller than ER collets, so you'll need more collets to hold the same range of shank sizes. Use them in CNC machines and drill presses.
