But every time I try to do 12L14 "leaded steel" a.k.a. leadalloy, which normally machines very easily, the parting blade likes to go along nicely and then suddenly hog in without any warning. I've broken 2 of the blades (1/2 x 0.060 HSS) in this learning experience. Still haven't found a solution. So for now I bandsaw 12L14 off and face the end to dimension.
