step 1: drill holes. For this, I am using a hammer drill. I have no great brand loyalty here….but here's the one I've been using for the past couple years. Holding up well, so far! Usually, I drill a pilot hole first, using a smaller sized drill bit (masonry SDS bits).This is a time saver–you first dill all the way through the stone, using a quarter inch sized drill bit or similar.

For instance, igneous rocks such as granite and basalt are generally denser than sedimentary rocks like sandstone and shale. A rock's density can also be affected by the presence of voids and fractures within it. ... While a jackhammer is a powerful tool for breaking rock, there are other methods such as traditional drilling and blasting ...

The first step in selecting a rock-breaking tool is to understand the type of rock you'll be working with. Different rocks have varying hardness, density, and fracture properties. Softer rocks like sandstone or limestone may require less power, while harder rocks like granite or basalt demand more robust tools.

With increasing tip width, the peak penetration force linearly increases, and the specific energy first increases and then decreases. The optimal rock breaking performance was obtained when the tip width was approximately 1 mm. Compared with the traditional rock breaking method, the preslotting method can significantly reduce the cutter load.

For example, granite and basalt are both igneous rocks with different chemical composition and structure and, therefore, different weathering rates. Rocks with minerals that crystallize late in Bowen's reaction series, like granite, are usually more resistant to chemical weathering than those with minerals that crystallize early, like basalt.
