Pete:
Any drill bit with a tungsten carbide point on it is meant to bash a hole in the masonary in front of it. There's no such thing as a masonry bit meant to cut a hole the same way a twist drill bit does. Putting a masonry bit in a drill that only rotates is just going to grind a hole in the masonry, and that will only work for very soft materials like brick mortar.
