Abstract: A knuckle deburring cutter and a method of knuckle for removal of burrs at a lower ball head hole of a knuckle and burrs in the locations where the lower ball head hole, a pinch bolt hole and a pinch bolt slot intersect one another. The knuckle deburring cutter includes a cutter shank in a circular bar shape having a diameter less than that of the lower ball head hole. A deburring cutter head is positioned at an end of the cutter shank with the shape of the deburring cutter head matching that of the pinch bolt hole. A sharp-angle part of lettering is positioned at an end of the deburring cutter head with a width of the sharp-angle of lettering being less than that of the pinch bolt slot. The knuckle deburring cutter and associated method provides benefits, such as low rejection rate, ease of machining, short production rhythm and the like.
