      ❓ Frequently Asked Questions
      Q What is the difference between the Standard (E) and Long (EL) series end mills?
      The Standard series (E) features a shorter overall length and cutting depth (H), making it ideal for general milling tasks requiring rigidity and stability. The Long series (EL) provides an extended flute length and overall reach, suitable for deep cavity machining or applications requiring greater projection from the holder.
      Q What is the difference between 2-flute (DP-2) and 4-flute (DP-4) end mills?
      2-flute end mills offer larger chip gullets, making them well-suited for softer materials and slotting operations where chip evacuation is critical. 4-flute end mills provide a smoother surface finish and higher feed rates, making them preferred for finishing passes and harder materials such as hardened steel or cast iron.
      Q What materials are these DP series end mills suitable for?
      The DP series end mills are rated Excellent (◎) for carbon steel, alloy steel, pre-hardened steel (up to ~55HRC), and nodular cast iron. They are also rated Good (○) for stainless steel. They are designed for a wide range of ferrous materials in precision CNC machining applications.
      Q What does the "G" designation mean in DP-4-G-E and DP-4-G-EL?
      The "G" designation in the DP-4-G-E and DP-4-G-EL series indicates a specific geometry or coating variant optimized for enhanced performance. Please refer to the product specification sheet or contact our technical team for detailed information on the specific geometric differences compared to the standard DP-4-E series.
      Q How do I select the correct shank diameter (d) for my application?
      The shank diameter (d) should match the collet or tool holder bore in your CNC machine. Common shank diameters in this series are 4mm, 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, and 20mm. For small-diameter cutting tools (D ≤ 4mm), a 4mm shank is typically used. For larger cutting diameters, the shank diameter is matched proportionally to ensure rigidity.
      Q What is the difference between Ball (B/BL), Square (E/EL), and Corner Radius (R) end mills?
      Square end mills (E/EL) have a flat cutting end and are used for general profiling, slotting, and facing. Ball end mills (B/BL) have a hemispherical tip ideal for 3D contouring, curved surface machining, and die/mold work. Corner Radius end mills (R) combine a flat end with a small radius on the cutting corners, offering improved tool life, reduced chipping, and better surface finish compared to sharp-cornered square end mills.
