      Frequently Asked Questions

      Q1 What is the difference between MTA and MTB Morse Taper Holders?
      MTA (Morse Taper Adapter) holders are standard adapters that connect HSK, BT, or SK spindle interfaces to Morse taper tooling without a tension screw mechanism. MTB holders incorporate a built-in tension screw system, which provides a more secure clamping force and is suitable for applications that require higher pull-out resistance during heavy-duty cutting operations.
      Q2 What spindle interface types are available for Morse Taper Holders?
      Our Morse Taper Holders are available in three main spindle interface types: HSK-A (HSK50A, HSK63A, HSK100A), BT (BT30, BT40, BT50), and SK (SK30, SK40, SK50). Each interface type is compatible with the corresponding machine spindle standard, ensuring precise and reliable tool holding performance.
      Q3 What Morse Taper numbers (MT.NO) are supported across the product range?
      The product range covers Morse Taper numbers MT1 through MT5. MT1 and MT2 are suitable for smaller diameter tooling (Φ10–Φ22mm), MT3 and MT4 for medium diameter tooling (Φ24–Φ50mm), and MT5 for larger diameter tooling (Φ55–Φ60mm). The specific MT number available depends on the spindle size selected.
      Q4 Is a tension screw or pull stud included with the MTB holders?
      Yes. For BT-MTB Morse Taper Holders, a long pull stud is included with each holder. For SK-MTB Morse Taper Holders, the tension screw is included. The specific tension screw specification for each model is listed in the product specification table to ensure compatibility with your machine tool setup.
      Q5 What do the Figure A and Figure B designations mean in the BT-MTA tables?
      Figure A and Figure B refer to different length configurations of the same Morse Taper number. Figure A typically denotes the shorter (standard) length version, while Figure B refers to the extended length version. Extended length holders (Figure B) provide greater reach for deep-hole machining or applications where additional clearance is required between the spindle and workpiece.
      Q6 How do I select the correct Morse Taper Holder for my application?
      To select the correct holder, first identify your machine spindle interface (HSK-A, BT, or SK) and its size (e.g., BT40, SK50). Next, determine the Morse Taper number required by your tooling (MT1–MT5) based on the tool shank diameter. Then choose between MTA (standard) or MTB (with tension screw) based on your clamping requirements, and select the appropriate length (Figure A or B) based on your machining reach requirements. Refer to the specification tables for exact dimensional data.
