What is the best drill bit for ceramic tiles and do you need a special bit to drill through tile? A bit that is made specifically for drilling through ceramic tile is the best way to ensure that you are able to drill through without breaking or damaging the tile or your bit. These bits have strong, long-lasting asymmetrical carbide tips that help them get through tile smoothly and cleanly. Diamond core bits can be used for heavy-duty industrial or granite tiles. It is also important to use a rotary drill and not a hammer drill, as hammering can very quickly break and damage ceramic tiles.

Do you need a special drill bit for porcelain or can any ceramic drill bit do the job? There are three main types of drill bits for ceramics - standard ceramic tile bits, glass and tile bits and diamond core bits. While glass and tile bits may work for regular tile, diamond core bits are made for granite tile. A specialised ceramic tile bit is the best choice to drill through porcelain without the risk of damaged tile or drill bit. Make sure that you use this bit in a rotary drill. Hammer drills can end up breaking the tile as they are not made for ceramics.

Can you drill into ceramic? Absolutely. You can drill into just about every type of material, as long as you use the right drill and the right drill bits for the material you are drilling into. Ceramic tile drill bits are the best choice for drilling into porcelain tiles. For granite tiles, a diamond core drill bit is a better choice. A general glass and tile drill can be used for medium-wear tiles as well as glass. Whichever drill bit you use, make sure that you use a rotary drill rather than a hammer drill, which can easily break ceramic.

How do you drill into ceramic tile without breaking it, you may be asking yourself? There are two answers to this question. First, you need to choose the right drill. Hammer drills are made to break through tile, with a vibrating action that will destroy tile very quickly. Rotary type drills will drill through tile, without the risk of damage. Next, you need to choose the right drill bit. There are many types of drill bits and each is made for the material you are drilling. A ceramic tile drill bit is always the best choice to get the job done properly.

A question we’ve often asked at Ruwag is, “Can I use a hammer drill on ceramic tile?” The answer to this is a definite no. With a hammering action that allows them to break through material rather than drill into material, hammer drills are best suited to masonry such as brick and concrete. They are not made for materials such as ceramics, however, and should not be used on tile. Using a hammer drill on ceramic tiles will shatter or break the tile very quickly when using the hammer function. Instead, use a rotary drill when drilling into ceramic tile.
