Yes, it's best to use a carbide-tipped masonry bit when drilling into concrete. These bits are harder and more durable than standard bits, so they're designed for drilling into tough surfaces like concrete. A different bit is likely to break and pose a safety hazard so you'll definitely want to stick with one that's specially designed for concrete. 

Drying concrete faster after rain is tricky because you’d need to increase the temperature or airflow over your slab, both of which are challenging to do outdoors. It can help to remove water from your concrete quickly, though, as the faster you remove rain from the surface, the lower the risk of the water affecting the ratio of your concrete mix. Use squeegees or mops to remove water, and consider covering your slab with a tarp to protect it from future rainfall.
