    Designed to run at high speeds with very little vibration, these motors often drive smooth, steady cuts in CNC machines. They’re brushless, so they run faster, last longer, and are more efficient than brushed DC motors. They also have a higher torque-to-weight ratio. You’ll need a brushless DC motor driver (not included) to power and control these spindle motors. They’re not compatible with automatic tool changers.
    They come with an ER-11 collet for holding round-shank tools, such as router bits, drill bits, and end mills. Collets for larger shank sizes are sold separately.
    Total Indicated Runout (TIR) Accuracy—Total Indicated Runout (TIR) is a measure of rotational smoothness—the lower the value, the less wobble a rotating tool will have and the more accurate it will be. When choosing a replacement spindle motor, you want one that has an equal or better TIR.

    ER Collets

    The most widely used type of collet, these collets hold cutting tools in ER collet chucks for milling, drilling, and routing. 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.

    Sealed

    Made with high-performance machining in mind—these collets not only grip your cutting tool but also direct coolant to the tool's cutting edge. They have coolant channels designed to work with through-spindle coolant (TSC) systems to clear chips and reduce heat from friction, resulting in clean cuts and long tool life. Place them directly into your ER collet holder, no need to fuss with special collet nuts, coolant rings, or repositioning hoses and nozzles with every setup change.
    You get the benefits of using an ER collet, too. Spring slots clamp evenly around the shank to minimize runout for accurate cuts. Keep in mind, these collets must form a tight seal around the tool shank for proper coolant delivery, so match the shank size to the collet size exactly for the best results.
    Sealed Coolant Delivery Collet—Sealed collets run coolant through the cutting tool, so they only work with tools that have coolant holes. Since the coolant runs through the tool, they’re a better choice for deep-hole drilling and high-speed machining than collets with angled ports. Steel seals are built into their body, so they withstand higher pressure and last longer than collets with rubber seals.
    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 too frequently.

    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. 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.

    Secure ER collets inside collet chucks and fixtures. Tightening these nuts squeezes the collet around the cutting tool to clamp it firmly in place.
    Low Friction—Low-friction coated nuts tighten more smoothly than standard collet nuts for even clamping and longer tool life. Replace them when the coating wears away.
