      ? Frequently Asked Questions
      Q What is the main advantage of DSK collet over ER collet?
      The DSK collet features a smaller taper angle and longer clamping length compared to the standard ER collet, resulting in higher clamping strength and superior concentricity. This makes it ideal for high-precision machining applications that demand tighter tolerances and improved tool stability.
      Q What is the TIR runout specification for the GSK/DSK collet chuck series?
      All GSK and DSK collet chuck models in this series achieve a TIR (Total Indicator Reading) runout of ≤0.003mm, ensuring exceptional precision and repeatability for demanding CNC machining operations.
      Q What balance grade and maximum speed are these collet chucks rated for?
      The HSK-A-GSK and SK-GSK series collet chucks are balanced to G2.5 at 25,000 rpm, while the SK-DSK series is balanced to G2.5 at 20,000 rpm. These balance ratings make them suitable for high-speed machining centers and spindle applications.
      Q Are collets, axial fix screws, and wrenches included with the collet chuck?
      No. The axial fix screw ("T"), collets, and wrenches are not included with the collet chuck and must be ordered separately. Please refer to the specification table for the compatible collet type (e.g., DSK6, DSK10, DSK16, DSK20, DSK25) when placing your order.
      Q What shank interfaces are available for the GSK/DSK collet chuck series?
      The collet chuck series is available with HSK-A (HSK40A, HSK50A, HSK63A, HSK100A) and SK (SK30, SK40, SK50) shank interfaces, covering a wide range of machining center spindle standards to suit different machine tool requirements.
      Q What is the purpose of the DSK Collet Extender and what sizes are available?
      The DSK Collet Extender (C20 series) is designed to extend the reach of DSK collets for deep-cavity or hard-to-reach machining applications. It is available in DSK6 and DSK10 configurations with overall lengths of 120mm, 150mm, and 180mm, providing flexible options for extended-reach precision toolholding.
