      Result: Compared to standard milling cutter, screwed-on milling cutter with solid carbide holder enjoys a much longer tool life and lighter vibration.
      ❓ Frequently Asked Questions
      Q What is a screw-on milling cutter and how does it differ from a standard milling cutter?
      A screw-on milling cutter uses a threaded connection to attach the cutter head to the shank, allowing quick and precise head replacement without removing the entire tool from the machine. Compared to standard milling cutters, screwed-on milling cutters with solid carbide holders offer significantly longer tool life, reduced vibration, and greater machining flexibility — especially in deep-reach applications.
      Q What inserts are compatible with DEREK screw-on milling cutters?
      DEREK screw-on milling cutters are designed to be compatible with DEREK brand inserts as well as leading third-party brands. Depending on the cutter model: ASR and RCF series are compatible with DEREK or HITACHI inserts; EMR, TRS, 300R/400R, and AJU series accept DEREK or Mitsubishi inserts; and BF series supports DEREK or WALTER inserts.
      Q What is the advantage of using a DS Solid Carbide Holder with a screw-on cutter?
      The DS Solid Carbide Holder provides superior rigidity and vibration damping compared to steel shanks, which is especially beneficial in long-reach or deep-cavity machining. Test results show that combining a DS solid carbide holder with a screw-on cutter (e.g., DS-C19-M10-150 + 300R-20-M10-2T) results in a much longer tool life and significantly lighter vibration than a conventional steel tool shank setup.
      Q What is the difference between the RCF and BF ball-nose cutter series?
      The RCF series (Screw-on Ball-nose Cutter For Roughing) is designed for heavy material removal with a robust insert design suited to roughing operations. The BF series (Screw-on Ball-nose Cutter For Finishing) is optimized for precision finishing passes, offering finer surface quality. Both feature a screw-on design for easy insert replacement, but they use different insert types to meet their respective machining requirements.
      Q What diameter and thread size options are available for DEREK screw-on cutters?
      DEREK screw-on milling cutters are available in a wide range of diameters, typically from 16mm to 35mm for cutter heads, with thread sizes of M8, M10, M12, and M16 to match various holder and spindle configurations. The DS Solid Carbide Holder extends from 12mm to 32mm in diameter with lengths ranging from 100mm to 400mm, providing versatile reach options for different machining depths.
      Q Can the AJU screw-on cutter be used for both drilling and milling operations?
      Yes, the AJU series is specifically designed as a Screw-on Cutter For Drilling Milling, making it a versatile choice for combined drilling and milling operations. It supports multiple insert options (such as CCMT and CPMT types) to handle different cutting tasks, and is compatible with both DEREK and Mitsubishi inserts for added flexibility in production environments.
