What kind of steel is called drill rod?

The drill shank could be of high speed steel or tungsten carbide.add. The actual drill rod will be of tool steel, for it has to take a lot of hammering at the top. The lengths of rod are made in increasing lengths, increasing in about 6 ft increments. This is so one can drill six ft more, then go to a longer drill. That was in the old days of manual drilling. In the 50's the drill bits themselves had inserts of tungsten carbide - then a new material. Prior to that the bits were just hardened steel.So the drill rod would be a little more than an inch in diameter, with the drill head screwed on the end. The rods have a hole through their length through which air is periodically blasted to clear debris from the hole. This 'dry drilling' is now known to have been hazardous to humans on account of the silica dust discharged.

Is cold rolled steel rod harder than drill rod?

I believe drill-rod is harder than ordinary, cold-rolled steel - I cant give the specs to back that up definitively, but in my 14 yrs of industrial maintenance experience, I believe that to be correct. +++ I agree if I am right in thinking that "drill-rod" is the material called "silver-steel" in the UK. This is an alloy capable of being hardened and tempered to make cutting-tools, spindles etc, but is pretty tough to machine even in its annealed state. Cold-rolled mild-steel in turn, is tougher than hot-rolled m.s. but I don't know if it is any stronger. That would depend on the specific alloy rather than process.
