  • Solid carbide necked shank end mill
  • Entire shank is reduced to .393 diameter up to the end of the flute.
  • This tool allows you to mill a pocket or wall up to 4.4 inches deep.
  • Shank will not rub against the side wall, reducing taper and cutting forces
  • Side wall surface finish will be greatly improved
  • A collet chuck is recommended for these tools because of the stepped down non standard shank size
  • We recommend a TG100-13/32 collet or a ER16,ER20,ER25,ER32, and or ER40 collet X 10mm diameter
  • 3 flute high helix with extra deep flute and 3rd land edge prep
  • Reduced shank 3 flute end mill finisher has an extra long shank, perfect for deep pocketing and mold making
