feather and wedge method | how to split boulders and stone slabs

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.

Difference Between Basalt and Granite

Basalt Vs. Granite . Summary of Basalt Vs. Granite. Basalt is an igneous, volcanic rock that forms commonly in oceanic crust and parts of continental crust. It forms from lava flows which extrude onto the surface and cool. Its principle minerals include pyroxene, feldspar, and olivine. It is common both on Earth and other planetary bodies.
