Frequently Asked Questions
Q: Do I need a specific holder for these bars? A: Yes, your lathe tool post needs to accommodate a 1/2″ shank, or you require a dedicated 1/2″ boring bar holder block.
Q: Are the cutting tips replaceable? A: The supplied data does not specify indexable inserts; standard solid bars require re-sharpening when dull.
