Why Drill Bits Matter For Tile

When it comes to working with tile, using the wrong type of drill bit can shatter or crack the tile, making your project even more difficult because you'll need to repair or replace damaged tiles. So, why use a diamond-tipped bit on tiles? The diamonds in the bit create friction, and this works to rub and grind the tile, making the hole that you need.

Because of the friction created as you drill, bits and tiles can heat up, which is why you need to keep the bit wet to stay cool while drilling. A wet containment piece or ring is a suction tool that holds water while you d to lubricate and cool the bit. The location of the containment piece also acts as a guide, so you know you are drilling in the specific area for the hole.

When it comes to the tungsten carbide tip, you'll need to maintain a slow and steady speed to prevent either damaged or cracked tile and broken drill bits.

Below you'll see some examples of drill bit sets. Of course, it is always possible to purchase individual bits, but opting for a full set provides cost-effective, high-quality options.
