Listers, please give me advice.
Due to inferior steel, a cotter ring has rusted badly, and I am unable to remove the remnants from the pin.
So far, a hardened-steel drill bit (Irwin brand) is simply enlarging the hole around the edges, but not removing the ring remnants.
Is there chemical solution? 
Any thoughts would be greatly appreciated.
