Influencing factors
Clearance dimensions / plunge cut for cut knurling
„ „ Clearance dimension for cut knurling – workpiece collar
Due to the design-related inclination
b (30°) of the knurling head and
the overhang of the cover plate, knurling up to a collar is not possible
with a cut knurling tool.
Dimension a corresponds to the increase in the step (mm).
Dimension b corresponds to the minimum clearance for the respective
knurling wheel (Ø specified in mm).

„ „ Minimum width of the plunge cut – cut knurling
If knurling is to be applied in the middle of the workpiece, a “knurling undercut”
is needed (the knurling wheel requires a chamfer for centring).
Depth of the plunge cut: at least 1/2 pitch + 0.3 mm.
