Wet diamond drilling system
No-load speed (min
Wet core drill bit diameter (mm)
Wet diamond drilling system
No-load speed (min
Wet core drill bit diameter (mm)
The given speeds are to be viewed as maximum speeds for the given wet diamond core drill bit diameters.
Depending on the property of the material to be drilled, such as concrete with steel reinforcement of differ-
ent thicknesses, the speed is set "by feel". When drilling through concreted in steel with large wet diamond
core drill bit diameters the 1st gear is always set.
