Hold collets tightly in CNC machines with HSK taper spindles for milling, drilling, and routing. Made from high-grade nickel chrome-moly steel, these chucks remain rigid and accurate while resisting wear. They’re also precisely balanced for high speeds, which leads to longer tool life and better finishes on workpieces compared to less balanced chucks. They meet DIN and ISO standards for compatibility across machines with HSK spindles.

These chucks have nuts with internal ball bearings for the smoothest and most uniform clamping. This results in a stronger grip, better accuracy, and less wear on your tool. Insert your collet and tighten the nut to clamp your tool in place. They have a collet stop screw that sets the tool depth in the chuck for consistent, repeatable performance when you change tools. An RFID chip hole holds a small RFID tag for automatic tool identification and tracking.

To route coolant through these chucks without washing away the grease in your spindle, install HSK coolant tubes. 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.
