Variable angle's processing cutter

The utility model relates to a variable angle's processing cutter, including blade, tool bit, cutter arbor, the clamp plate that has the through -hole and screw, this tool bit includes blade tip part and hollow cylinder portion, and the blade fixed mounting be in on the blade tip part of tool bit, the one end of cutter arbor has the cylinder somatic part, and tool bit and cutter arbor are connected in the inside and outside spline tooth cooperation of cylinder somatic part through setting up. Adopting such variable angle's processing cutter, when unscrewing the screw, taking off clamp plate and tool bit, change the number of teeth, size, shape and the tooth top of spline tooth and the cooperation position of tooth root, just can conveniently change the cutting angle that processes the cutter, process intensity and machining precision, increased and processed the cutter to the application scope of machining part in the machining field, the elongated hole of applicable counter shaft class, structure carries out
