"JUSTDOWORK"... you didn't mention the material that you are trying to cut. Based on the fact that you can't make much progress using a hack saw... I would guess that the material is steel. In this case, you will definetly need a new hack saw blade or use a die-grinder or dremel tool. Using a drill is dangerous...unless you have something to hold the bars in place.
Are you trying to make one or two slits? If two slits, then use a hack saw...that will be the fastest. If one slit, use a dremel or grinder.
Good Luck!
