(Not sure where to post this, there are too many sub-forums these days.... I digress) I have a 6mm (small) stainless steel bolt sheared flush into an aluminum block. I tired using an easy-out, but the bolt was jammed harder than I thought and the easy-out snapped off 1/16" below the bolt surface. Any suggestions on how to drill this mess out now? My plan is to heli-coil.
