An end mill is specified by four dimensions: the cutting diameter, the flute length, the shank diameter and the overall length. The tables below list the standard sizes in chapter 04 of our 2026 catalog, grouped by series, with each diameter also given in inches.

How to read the tables

  • Dia. D1 is the cutting diameter. All end mills in this chapter are ground to h7 on the diameter.
  • ≈ in is the cutting diameter divided by 25.4, rounded to three decimals. It converts the metric size; it is not an inch-size tool.
  • Flute length L1 is the length of the cutting flutes. Choose one that covers your depth of cut.
  • Shank D is the diameter that goes into the holder. Shanks are metric. Some sizes are listed with two shanks, for example Φ4 with a 4 mm or a 6 mm shank.
  • Overall length L: choose the shortest the part allows; a shorter tool is stiffer.
  • For ball nose end mills the ball radius is half the diameter. For tapered ball nose end mills, D1 is the tip diameter and α is the taper angle per side.
  • Where the catalog lists the same dimensions under two order codes, the size appears once here. A few sizes from the catalog tables are not listed here. If you need one of them, ask us.
