      ❓ Frequently Asked Questions (FAQ)

      What workpiece materials are these DP series end mills suitable for?
      According to the Work Piece Table, these end mills are highly recommended (◎ Excellent) for Carbon Steel, Alloy Steel, Pre-hardened Steel, Hardened Steel (up to 55HRC), and Cast Iron/Nodular Cast Iron. They are also suitable (○ Good) for Stainless Steel machining.
      When should I choose the 2-flute (DP-2) vs. 4-flute (DP-4) configuration?
      2-flute end mills (like DP-2-E and DP-2-EL) provide larger chip pockets, making them ideal for roughing, slotting, and efficient chip evacuation. 4-flute end mills (like DP-4-E and DP-4-G) offer higher core strength and rigidity, making them excellent for side milling, finishing, and high-feed machining where a smoother surface finish is required.
      What is the difference between the Standard (E/B/R) and Long (EL/BL) series?
      The Long (EL/BL) series features a longer cut length (H) and overall length (L) compared to the Standard (E/B) series. This allows for deep-pocket machining, extended reach, and profiling in deep cavity molds, though feed rates may need adjustments to account for the longer overhang.
      What are the advantages of the Corner Radius (DP-R) end mills?
      Corner Radius end mills feature rounded cutting edges (R) instead of sharp square corners. This design helps distribute cutting forces more evenly, significantly reduces corner chipping, extends tool life, and allows for the machining of precise radius transitions in mold and die cavities.
      Can these end mills machine hardened steels above 55 HRC?
      These specific models are optimized and highly recommended (◎) for workpiece hardness up to 55 HRC. For materials from 55 HRC to 68 HRC, it is recommended to consult specific high-hardness series or carefully adjust the cutting parameters (speed, feed, and depth of cut) to avoid premature tool wear.
      What do the 'Figure A' and 'Figure B' designations represent in the tables?
      'Figure A' and 'Figure B' refer to the neck/shank configuration design of the end mills. Typically, Figure A represents a straight shank design where the cutting diameter (D) is smaller than the shank diameter (d), whereas Figure B represents a straight shank where the cutting diameter is equal to the shank diameter.
