[QUOTE="sidesh0wb0b, post: 359348, member: 7594"] 2.7mm should be a good enough offset. and if it wasnt, then you would most likely see the same issue in both pucks. (i am presuming the offset on both was 2.7mm) was the chipped unit nested close to the bottom of the puck? we just ran into a tooling error for the first time regarding a unit nested too close to the top of the puck. not saying it would cause chipping, just tossing out ideas. otherwise i lean toward tool life. margins look plenty thick enough, and 2.7mm offset is more than the standard 2.5mm we run on 90% of our units. what size tools do you run? 2mm, 1mm, .6mm, .3mm?
