      Frequently Asked Questions
      QWhat is the difference between the DH-2-E and DH-4-E square end mills?
      The DH-2-E is a 2-flute square end mill designed primarily for milling in grooves, offering excellent chip evacuation. The DH-4-E is a 4-flute square end mill suited for side-milling and grooving, providing higher rigidity and better surface finish due to more cutting edges. Both support high-speed dry-cutting.
      QWhat materials are the DH series end mills suitable for?
      The DH series end mills are rated excellent (◎) for pre-hardened and hardened steels up to ~55HRC and ~68HRC, and good (○) for ~50HRC steels and nodular cast iron. They are optimized for high-hardness steel machining and are also compatible with carbon steel and alloy steel applications.
      QWhat is the advantage of the micro series end mills such as DH-2-ES and DH-2-BS?
      The DH-2-ES (Square/Micro) and DH-2-BS (Ball/Micro) feature micro neck diameters and micro flute diameters respectively, enabling high-precision performance at high spindle speeds. They are ideal for fine detail work, intricate contours, and precision machining where tight tolerances are required.
      QWhen should I choose a Long Neck / Short Flute end mill like the DH-2-EP or DH-2-BP?
      Long Neck / Short Flute end mills such as the DH-2-EP and DH-2-BP are designed for rib-processing, deep cavity machining, and operations requiring reach into confined areas without tool interference. The short flute reduces vibration while the long neck provides the necessary clearance for deep-feature machining.
      QWhat is the purpose of the corner radius end mills (DH-4-R, DH-4-RF, DH-4-RP)?
      Corner radius end mills add a small radius to the cutting edge corners, significantly improving tool life by reducing edge chipping and stress concentration. The DH-4-R is for standard operations, the DH-4-RF features a short flute for high-feed high-speed cutting, and the DH-4-RP combines a long neck with short flute for deep pocket-milling applications.
      QDo the DH series end mills support dry-cutting?
      Yes. The DH-2-E, DH-4-E, DH-2-B, and other series are specifically engineered for high-speed dry-cutting operations. Their advanced coatings and geometry allow efficient heat dissipation and chip evacuation without the need for coolant, making them suitable for clean and efficient machining environments.
