Iron Turning Blanks, although useless on their own, can be modified in the Turning Table to be turned into a handle or a drill bit, required for crafting the Mining Laser and Diamond Drill respectively.

In IC2 Experimental the entire Turning Table recipe became depreciated and no longer craftable.
All previous recipes that required Turning Blanks no longer require them.
