    Threaded Mount

    Thread these chucks onto the spindle of portable drills and stationary machines to hold bits. They're a keyed chuck, so they hold the bit tightly, preventing it from slipping under load. Use the included key to tighten and loosen the jaws. If your machine doesn’t have a threaded spindle, mount them with a threaded drill chuck arbor.
    To maximize grip and minimize wobble, choose a chuck where your drill bit diameter falls in the middle of the shank size range.
    Medium Duty—Medium duty chucks work for most drilling jobs in metal, wood, and plastic. A one-piece sleeve keeps them rigid when drilling in hard materials, such as steel. For accuracy and longevity, they have hardened wear points and center-ground jaws that grip the bit evenly.
