Master Wholesale President Blake Adsero shows you how to dry core drill in tile using a RockMaster Diamond Core Drill Bit.
You will need two pieces of wood, one for a template, and one to put under the tile so you don't drill into the surface you are working on. Start by using a hole saw wood cutting bit of the same diameter to cut a hole in the wood template. Once the hole is cut line up the template with the spot on the tile or stone that you wish to core through.
Before you switch to the RockMaster dry core bit, remove the center drill bit from the core bit with an Allen Wrench. The core bit works much faster without it.
Once you have done this, start drilling using the high speed setting on your drill. After the hole is started you may remove the template to finish the core hole.
