What drill do you use to drill stone?
Stone is the most popular building material together with wood. The reasons for this are simple: it is sturdy and durable, it insulates and it is relatively cheap and easy to produce. There are quite a few types of stone you can drill into: brick, grout, gas concrete and plaster are the most common ones. Incidentally, concrete is missing in this list. When we talk about drilling in stone, concrete is always excluded. Not that concrete is not a stone, but it has its own category when it comes to drilling (when drilling in concrete you use a drill or combi hammer in combination with a concrete drill).
Drilling in stone
With what kind of drilling machine you drill into stone depends on the hardness of the stone. In gypsum, aerated concrete (not to be confused with ordinary concrete) or sand-lime brick, you drill with almost every drill. A rotary movement is sufficient for these types of stone. If you drill into harder stone as brick or grout, use a hammer drill. In addition to a rotating, this makes a pulsating movement with which your rock is broken. The number of strokes per minute can usually be regulated; start slowly to avoid unnecessary damage.
The right drill bit
Drilling in stone with the wrong drill produces relatively little results. A stone drill (or a concrete drill) is a must to carry out the job as well as possible. This type of drill has a blunt tip with wings that cause the stone to be knocked away. The difference between a stone and a concrete drill is in the material that made this point. With a masonry drill, the entire drill consists of the same material, while with a concrete drill bit the point is made of even harder metal to effectively pass through the hard concrete.
If you drill in stone, you drill with a regular (cordless) drill when it concerns the softer types of rock. Drilling in brick and grout? Then use a hammer drill. Of course you drill with the necessary preparation.
