      Frequently Asked Questions
      Q What is the difference between MGEHR/L and MGEVR/L grooving tool holders?
      MGEHR/L holders are external grooving tool holders designed for standard turning applications, available in a wide range of shank sizes (12×12 to 32×32 mm) and groove widths (1.5 mm to 8 mm). MGEVR/L holders are a specific external grooving series optimized for narrower groove widths (2 mm to 4 mm) with a 20×20 mm shank. Both series are compatible with DEREK MGMN-series inserts.
      Q What insert types are compatible with MGIVR/L internal grooving boring bars?
      MGIVR/L internal grooving boring bars are compatible with DEREK MGMN series inserts including MGMN150-G, MGMN200-G/M, MGMN250-G/M, MGMN300-M/G, MGMN400-M/G, MGMN500-M/G, and MGMN600-M/G, depending on the groove width required. The corresponding screw sizes range from M4*10N to M5*12N.
      Q How do I select the correct QF face grooving tool holder for my application?
      When selecting a QF face grooving holder, you need to consider: (1) the workpiece diameter range (D min–max), which determines the H-suffix (e.g., -48H, -60H) for the LL/RR type or L-suffix for the R/L type; (2) the groove width (W), available in 3 mm, 4 mm, 5 mm, and 6 mm; and (3) the tool overhang (T), available in short (10/13 mm) or long (17/22 mm) options. Match these parameters to the specification table to find the correct holder.
      Q What are the SNGR/L holders used for, and what inserts do they accept?
      SNGR/L holders are small-diameter internal grooving boring bars designed for very tight bore diameters starting from as small as 10 mm (SNGR/L08H07). They accept dedicated DEREK grooving inserts: 7GR200 (for 2 mm groove width) and 8GR300 / 9GR300 (for 3 mm groove width). The clamping screws are M2.2 or M2.5 type, and they use a Q06 or Q08 wrench.
      Q What is the purpose of the "-T10" and "-T15" suffix in MGEHR/L specifications?
      The "-T10" and "-T15" suffixes in MGEHR/L specifications indicate a reduced tool overhang (T dimension). For example, MGEHR/L2020-3-T10 has a T value of 10 mm instead of the standard 18 mm for the -3 series. This reduced overhang is used when machining in restricted spaces or when a shorter cutting edge projection is required to improve rigidity and reduce vibration during grooving operations.
      Q What are ZQ tool holders used for, and how do they differ from QE/QF holders?
      ZQ tool holders are external parting and grooving holders designed to accept ZQMX-series inserts (ZQMX3N11-1E and ZQMX4N11-1E), which feature a unique clamping mechanism. They are available in shank sizes from 16×16 mm to 32×32 mm with groove widths of 3 mm and 4 mm. Unlike QE/QF holders that use DEREK ED/FD/GD-type inserts with a screw-clamp system (M6*20Q), ZQ holders use a top-clamp or wedge-style insert seating with M5*17Q or M6*20Q screws, making them suitable for high-feed parting and deep grooving applications.
