How do I stop my core drills from clogging?

Core drills won't clog up so long as plenty of water is used which will wash out the debris as you drill.

Try drilling in an up and down motion which will allow more water to flow up inside the core. If they still clog it could be because the material you're drilling is too soft, they're designed to drill through hard material such as gemstone and glass.
