    R8 Taper to Jacobs Taper Drill Chuck Arbors

    Image of Product. Front orientation. Contains Annotated. Drill Chuck Arbors. R8 Taper to Jacobs Taper Drill Chuck Arbors.
    Adapt machines with R8 taper spindles to mount Jacobs taper drill chucks. These arbors are made of hardened steel and are precision ground for accuracy. They thread onto your machine’s drawbar for a secure connection. Strike the top of the arbor to seat them onto a drill chuck. To separate them, use a drill chuck removal tool.
    Economy—Economy arbors are great for occasional or low-volume jobs.
    Industrial—Industrial arbors are harder and more wear resistant than Economy arbors.

    Keyless

    Chuck

    Keyed

    Chuck

    Minimize runout and slippage under heavy cutting forces from drill presses and Bridgeport milling machines. These chucks have an integrated arbor for a one-piece design that makes them more accurate and compact than chucks with a separate arbor. Made of hardened steel, they resist wear from repeated use. They thread onto your machine’s drawbar for a secure connection.
    To maximize grip and minimize runout, choose a chuck where your drill bit diameter falls in the middle of the bit shank size range.
    Keyless Chuck—Keyless chucks let you swap bits in and out with a quick twist of the sleeve. As torque increases, their grip will tighten. These chucks only tighten in the clockwise direction, so they may loosen under heavy reverse loads, such as during left-hand drilling.
    Keyed Chuck—Keyed chucks use a worm-and-gear design to deliver exceptional grip on bits for the highest torque and accuracy when drilling in hard materials. They're so strong they can even be used for light duty milling in soft materials such as aluminum. Use their Torx key to tighten and loosen the chuck.
    McMaster-Carr Approved—McMaster-Carr approved chucks are made on the same equipment that once produced Jacobs chucks in Europe, so you get high-quality performance without the brand-name price.
    Albrecht—Albrecht chucks are known for their unmatched quality. Made in Germany, every chuck undergoes multiple inspections and tests to ensure they operate smoothly and keep your bits aligned over their long life.

    Quick-Change Milling Machine Tool Holders

    Image of System. Front orientation. Exploded view. Contains Annotated, MultipleImages. Milling Machine Tool Holders. Quick-Change Milling Machine Tool Holders.
    Swap tool holders in seconds without a wrench. This R8 quick-change system replaces conventional drawbar setups that require multiple turns to change tooling. A brass locking button and spring-loaded collar allow one-handed tool changes, so you can move quickly between drilling, milling, and facing operations. The R8 body installs in your milling machine spindle, letting you switch holders to reduce downtime between operations.

    Boring Milling Machine Tool Holders

    Instead of widening a hole using a lathe, which turns the workpiece while the cutting tool stays still, use these holders to turn your boring bar in a milling machine and keep the workpiece stationary. They’re good for creating holes that are too large to drill or a diameter you don’t have a drill bit for. To help you bore holes to precise diameters, these holders have an adjustment dial with fine increments. Mount them in your milling machine using their shank. They’re also known as boring heads.

    R8 Taper Collet Chucks

    Image of Specification. Front orientation. Contains Annotated. Milling Machine Collet Chucks. R8 Taper Collet Chucks.
    Hold collets tightly in Bridgeport and other manual machines with R8 spindles to grip tools for milling, drilling, and routing. These chucks let you use the same ER or TG collets as other machines. This reduces the number of collets you need while also giving you a strong grip on your tools. Insert your collet and tighten the nut to clamp your tool in place. Internal threads on the shank let you connect them to your machine’s drawbar system.
    To maximize grip and minimize runout, choose a chuck where your tool diameter falls in the middle of the bit shank size range.
    Collet Stop Screw—Chucks with a collet stop screw set the tool depth in the chuck for consistent, repeatable performance when you change tools.
