Did you try using a cutting lube for the rubber? WD-40, dish soap, etc? I've learned that when drilling holes, (with any type of drill bit) the holes drill easier, and the bits last longer if lube is used.

FWIW, call around to find a sharpening service. They should be able to sharpen those step drills too, if they can sharpen regular drill bits.
