How to Hand Drill Holes in Stone and Concrete
Handheld rock drills are still very relevant in specific instances. They weigh much less than motorized drills and are far smaller. Bolted rock climbing anchors are still commonly installed in hand drilled holes.
I love the idea of the tool going full circle--from hand, to pneumatic, to electric (and also battery powered), and then back to hand--but with a modern bit. Wow!
