12 1/4" New/Surplus 5 blade PDC drill bit. This bit is new/surplus from Smith Tools, but it is a much older design than what is used now. It has 6-5/8" API Reg pin. Shipping will be via an LTL freight carrier so you will need the ability to unload it with a fork lift or loading dock. If you have an issue with shipping please let me know and we will work with you to figure out a solution. If you have any questions feel free to ask. We sell drill bits in sizes from 3" to 36" in both new and rerun including PDC bits, tricone bits, hammer bits, drag bits, and hammers. Visit our website for a full list of products.
