Upcut spiral router bits are perfect for creating quick and efficient grooves, slots and dados in hardwood, softwood, MDF, plywood and particleboard. The upcut grind directs woodchips up and away from the surface helping to prevent tool breakages and extending the life of the bit. These bits are the best choice for most standard milling operations. These bits are precision ground from M2 Hight Speed Steel (HSS) and will maintain a sharp edge.
