I'm surprised nobody has rated the Bosch HDS181-03 yet. This is great exercise. Rechargeable batteries have a large capacity and charge very quickly. The drill has plenty of torque and the hammer drill is a nice feature. Handling at low speeds is excellent. Markings are rarely necessary. On one occasion the chuck came loose when I came out of a wooden beam with a 12" long, 1/4" diameter universal drill bit. Knitted the pole on a chisel. I don't have a lot of arm strength so maybe I just didn't tighten them enough to get started. I don't use a drill very often, only at home. But it's a lot easier to use than my old geared drill and much lighter thanks to the small battery. This is a great help for me and I would buy it again.
