Wet or Dry? - Tormek
· wet grinding, the tool life is significantly prolonged, since less material is removed. The dry grinding method leaves a hard compacted burr, which is very difficult to remove. The evidence suggests that using a wet-grinding method gives a sharper edge and cleaner cuts with more than double the effective turning time between sharpening.
