Used for roughing in, an angle drill fits perfectly between studs and joists. Powerful enough to drill holes in white oak timbers, medium-duty angle drills easily cut holes for waste lines, vents, and wires in softwood for new construction. Features to look for in an angle drill include: weight distribution, trigger design, handle size, and speed change location. Optional features like slotted chucks, detachable cords, and clutches can make a big difference in your choice of an angle drill.
