      Frequently Asked Questions
      What is the difference between SER/L and SNR/L threading tools?
      SER/L tools are external (outside diameter) threading tool holders designed for turning centres, while SNR/L tools are internal (inside diameter) boring bar-style holders used for threading inside bores and holes. Both series are compatible with DEREK indexable inserts.
      Which inserts are compatible with the SER/L and SNR/L tool holders?
      Both SER/L and SNR/L tool holders are designed to accept DEREK brand inserts. The specific insert designation (e.g., 11ER/L, 16IR/L, 22IR/L, 27IR/L) varies depending on the holder model and corresponds to the insert size and thread profile required.
      What shim and screw combinations are needed for SER/L holders?
      Smaller SER/L models (H=10, H=12) do not require a shim and use M2.5*8 screws. Larger models from SER/L1616H16 onwards use STM16, STM22, or STM27 shims with corresponding M3.5*12, M4*16, or M5*20 clamping screws, plus side screws (M3*6N or M4*6N) for additional insert security.
      How do I select the correct SNR/L boring bar for my application?
      Selection is based on the minimum bore diameter you need to thread. Each SNR/L specification lists a "Min dia" value — choose a holder whose minimum diameter is equal to or smaller than the bore diameter of your workpiece. Also consider shank diameter (d), overall length (L), and the required insert size.
      What wrench sizes are used for these threading tool holders?
      The required wrench size depends on the model. Common wrench sizes across the SER/L and SNR/L ranges include Q06, Q08, Q10, Q15, and Q20. Larger holders typically require two wrench sizes (e.g., Q15 and Q10) for the main screw and side screw respectively.
      Are the SER/L and SNR/L tools suitable for both right-hand and left-hand threading?
      Yes. The "R" and "L" in the product designation (e.g., SER and SEL, SNR and SNL) indicate right-hand and left-hand versions respectively. Both orientations are available across the full range of specifications, allowing flexibility for various threading directions and machine setups.
