Before battery powered drills, woodworkers used hand drills to bore holes and drive screws. Nowadays, you just may want to work with your hands the old-fashioned way or you may be somewhere without power. Either way, there's nothing wrong with going old school especially when you know that most power tools aren't as responsive as hand tools. The best rotary hand drills have three jawed chucks with hardened teeth for tight grip and great concentricity that work well with round or hex bits. This drill has a 5/16" bit capacity and a 3-1/4" rotary plate with an overall length of 22-1/2" Imported.
