How To Drill Holes Through Rocks
Rating: 4/5 (2 votes)
Quite a few people have asked me how I drill my rocks, so I took photos of today's process to share with you.
I recommend drilling softer sedimentary rocks (sandstone, limestone, etc). When scouring the beach for rocks, these tend to be well rounded. Those that are not rounded are probably harder igneous or metamorphic rock and are likely to break apart while drilling or break your drill bit.
