CMT bull nose bits create beautifully finished edges on stair treads, window sills and shelves in a pass. Ad a final touch by using a cutter with a bead diameter wider than the stock thickness. CMT bull nose bits have bead diameters from 6,35mm (1/4?) to 25,4mm (1?) and each bit features carbide-tipped cutting edges, anti-kickback design and the orange PTFE non-stick coating trademark. Safety tips: to be used only on router tables equipped with a fence. Do not remove the workpiece while the bit is routing.
