S Class 3 User’s Manual
Basic operation 2-6
The offset is a very important parameter for a drag knife. The offset is the distance between the knife
centre and the knife tip.
NOTE: The knife offset should be set each time the knife is changed and should
be checked when the knife shows signs of wear.
NOTE: A typical knife offset for Summa knives is between 0.41 and 0.45 for
standard knives, between 0.90 and 0.97 for sandblast knives and between 0.49
and 0.52 for the 60° knife.
NOTE: Sandblast knives should be used when the material that needs to be cut
is thicker than 0.25 mm.
