    Compressing

    Deburr using your CNC machine without complex programming. These holders grip your deburring tools and extend and retract along the shape of your part to smooth away burs—no overcutting. All you need to do is tell your CNC machine which direction to go. Use them with ball burs.
    To mount these tool holders to your machine, you will need another rotary tool holder or a collet that accepts a 20 mm diameter shank, such as an ER-32 collet. They should not be held by hydraulic chucks or shrink-fit holders. To install your bur, you'll need an ER-11 collet. Use the spanner wrench (sold separately) to tighten the tool holder nut around the collet.
    These tool holders should not be used with cutting fluid; clear any fluid or debris off your workpiece before deburring.
    Fixed Spring Load—Tool holders with a fixed spring load apply a consistent amount of force. They apply force by pushing down (compression) when working on the front of your part and pulling back (tension) when working on the back of your part, so you can deburr both sides with a single holder.
    Adjustable Spring Load—Tool holders with an adjustable spring load have four levels of deburring force. They only apply force by pushing down (compression) on your part, so they can only deburr the front.
    Light Spring Load—A light spring load has a delicate cutting action, applying about the same amount of pressure as your pinky finger. It is ideal for aluminum, plastics, and other soft materials.
    Medium Spring Load—A medium spring load is best for moderate cutting action, applying about as much pressure as your index finger. Use it when deburring steel.
    Heavy Spring Load—A heavy spring load is best for aggressive cutting—it gives about the same force as pressing down with your palm. Use it on stainless steel and other hard materials.

    Image of Attribute. Top orientation. Contains Annotated. CAT Taper to Morse Taper Shank Adapters.
    Adapt CNC machines with CAT taper spindles to mount tools with a Morse taper shank, including drill bits, drill chucks, and reamers. These adapters are made of hardened steel to resist wear. Their shank is precision ground to the industry standard AT3 tolerance for a secure fit that minimizes runout in your machine spindle. They meet ANSI/ASME standards for CAT spindles to ensure compatibility. Internal threads on the shank let you attach a retention knob, so you can connect them to your machine’s drawbar system.
    Slide your tool into these adapters and then press firmly to seat it. To separate them, use a Morse taper removal tool.

    Morse Taper Shank Size Adapters

    Image of Attribute. Front orientation. CrossSection view. Contains Annotated. Machine Taper Shank Adapters. Morse Taper Shank Size Adapters.
    Change your Morse taper machine spindles and lathe tailstocks to mount tools with different Morse taper shank sizes. These adapters are precision ground for accuracy.
    Slide your tool into these adapters and then press firmly to seat it. To separate them, use a Morse taper removal tool.
    Adapters—Adapters are great when all you need is a simple size change. Their compact design makes them more rigid than extension adapters, so they vibrate less and your tools last longer. Also known as drill sleeves.
    Extension Adapters—Extension adapters add length to your tools while changing shank sizes. Use them to help access hard-to-reach places while machining. Also known as drill sockets.
    Nylon—Nylon adapters prevent bits from breaking under high torque and sudden jolts. Their sleeve is designed to break before your bit is damaged. If your spindle is scratched or slightly worn, the sleeve conforms to those imperfections to keep your bit centered.
    Steel—Steel adapters have a soft body that can be machined and then hardened for wear resistance. The tang is already hardened.
    Hardened Steel—Hardened steel adapters resist wear better than steel adapters.
