Check the listing for details. Criterion DBL-203D Boring Head Set- R8 shank. 1300A kit for Bridgeport mill.. Condition: Used. Listed at 459.00 USD. Gently used Criterion boring head kit from my personal tool box. This kit includes a nice fitted case, a DBL-203D head with a R8 shank and 5 assorted size bars along with the appropriate hex keys. Some of the bars have slight wear, but all still have a decent shape carbide edge. This kit is in overall great shape - I've only used it a handful of times over the twenty some years that I've owned it. I'm retiring and cleaning out some of my machinist tools.
