7.00mm Cobalt Drill Bit

This heavy duty jobber length drill bit is the proper size for 7mm barrel pins. The best way to do it is to drill at 17/64 and ream at 7mm but for those with a really good drill press that like to drill once at 7mm and pin it this is for you

  Good price on a hard to find tool. Never hurts to have 2. Will buy more as needed.
