      Frequently Asked Questions

      QWhat is a DCK boring adapter and what is it used for?
      A DCK boring adapter is a precision toolholder interface component used in CNC machining centers. It connects the machine spindle (HSK, BT, BBT, SK, CAT, etc.) to DCK-series boring tools, enabling precise inner diameter boring, back boring, and chamfering operations on workpieces.
      QWhat spindle interface types are available for DCK boring adapters?
      DCK boring adapters are available for a wide range of spindle interfaces including HSK-A (HSK50A, HSK63A, HSK100A), BT (BT30, BT40, BT50), BBT (BBT30, BBT40, BBT50), SK (SK30, SK40, SK50), and CAT (CAT40, CAT50), covering most standard CNC machining center spindle types.
      QWhat does the "L" suffix in the specification model number mean?
      The "L" suffix in a model number (e.g., HSK63A-DCK1-100L) indicates a long-reach or extended type adapter with a mid-section extension body (Figure B). These models include an additional diameter parameter (d) and extension length (L2), allowing the boring tool to reach deeper into workpiece cavities compared to the standard type (Figure A).
      QWhat is the difference between DCK Extension and DCK Reducer accessories?
      DCK Extensions are straight connectors that increase the overall reach of the boring assembly while maintaining the same DCK interface size on both ends (e.g., DCK 1-1, DCK 2-2). DCK Reducers allow connection between two different DCK interface sizes, enabling a larger boring head to be used with a smaller-shank adapter, or providing step-down compatibility across the DCK size range (DCK1 through DCK7).
      QWhat insert brands are compatible with the CR Chamfering Cutter?
      The CR Chamfering Cutter series is compatible with inserts from DEREK, KYOCERA, and MITSUBISHI. The insert model series VC**1103 and VC**1604 are specified for different cutter sizes, and each is secured with its corresponding locking screw and wrench.
      QHow do I select the correct DCK boring adapter size for my application?
      Selection depends on four key parameters: (1) your machine spindle type (HSK, BT, SK, CAT, etc.); (2) the required boring diameter (D), which corresponds to DCK sizes 1–7; (3) the required gauge length (L) to reach the machining depth; and (4) whether a standard (Figure A) or long-reach (Figure B, suffix "L") configuration is needed. Refer to the specification tables above and match the d1 (bore fit diameter) to your DCK tool shank size.
