2.2.3 Changing drag knife offset
A very important parameter for a drag knife is the offset. The offset is the distance between
the knife center and the knife tip.
NOTE: Knife offset should be set each time the knife is changed and should be checked if
the knife shows signs of wear.
Typical knife offset for Summa knives is between 0.41 and 0.45 for standard knives, and
between 0.9 and 0.97 for sandblast knives.
NOTE: Sandblast knives should be used when the material that needs to be cut is thicker
than 0.25mm.
