Abstract
A mill bit for the manufacture of a wind turbine blade includes an elongate based body having a proximal end, a distal end, an outer surface, and an internal bore that defines an inner surface, one or more flutes formed on the outer surface that defines one or more teeth, and an abrasive coating on at least a portion of the outer surface, wherein the one or more flutes are free of the abrasive coating. An abrasive coating may be selectively applied on the inner surface to provide flutes on the inner surface. Additionally, porting bores may be provided through the mill bit to fluidly connect the outside and inside of the mill bit. A method of making a mill bit is also described.
