I just purchased a router crafter and having trouble finding plunge bits. For spirals in need a 3/16" quarter round sears number 25567 or a 9/32" point cutting ogee. Most seem to have a bearing on the end. I need something that will plunge. Anyone have any source for this type of bit? I have cut flutes with a cove bit and it worked well. I tried cutting spirals with a V bit and it cut the pattern well but need something that will round off the corners. Thanks Larry
