Because inside diameters of graphite shafts can vary quite a bit, there is not one bit that would work for all. Also, it sounds like you are needing to drill down from the butt end of the shaft, which would require a long drill bit. Currently we do not carry a long drill bit that could do what our needing. 1/8" bit size is generally what you could use, but again, it would need to be on a 42" - 48" rod.
