What’s the difference between reamers and end mills?

  • Reamer is straight edge, end mill is a spiral edge.
  • Milling cutter has a bottom edge, but a reamer has no bottom edge.
  • Reamers are used to finish holes, while milling cutters can mill surfaces, grooves and side milling for different purposes.
  • The blade of the reamer is short and the neck is long, so it looks like a long dumbbell.
  • The cutter teeth of the end mill are relatively long, accounting for 1 / 2 ~ 2 / 3 of the overall length of the cutter. The neck is very short. The cutter teeth are spiral, and the number of teeth is relatively small, which looks very sharp.
