    Access hard-to-reach places while machining—these extensions add length to drill bits, arbors, and other tools with a Morse taper shank. Also known as drill sockets.
    Slide your tool in, then press firmly to seat it. To separate the tool from these extensions, use a Morse taper removal tool.
    Steel extensions have a soft body that can be machined and then hardened for wear resistance. The tang is already hardened.
    Hardened steel extensions resist wear better than steel extensions.

    Straight-Shank Collet Chucks

    Extend your tool holder’s reach or adapt it to fit different collet systems on manual and CNC lathes and machining centers. Made from hardened alloy steel, these chucks remain rigid and accurate while resisting wear—even at high speeds. Their shank is also precision ground for a secure fit that minimizes runout in your machine spindle. Insert your collet and tighten the nut to clamp your tool in place.
    These chucks have a collet stop screw that sets the tool depth in the chuck for consistent, repeatable performance when you change tools. They’re also through-bore coolant-compatible, so they can route coolant through their center to clear chips, improve the finish of your workpiece, and extend the life of your tool. If you have a machine that sends coolant through the spindle, pair them with an ER coolant control collet for the best results.
    To maximize grip and minimize runout, choose a chuck where your tool diameter falls in the middle of the bit shank size range.
