Double angle cutter offers the flexibility of milling on both sides. Teeth are placed on both sides at an equal or alternative angle. This means that it can be used by technicians preferring the right or left hands. The two surfaces intersect at an angle that allows you to cut from either side. Double equal cutters are only available 90, 60 and 45 degrees. This is because of the technicalities of doubling the cutting edges. Either side is as strong and effective as the other.
