In order to attract customers, the advantages of a cordless drill are obvious and worthy of emphasis. The 48-volt battery is more powerful than those on similar drills (or so it seems). This means you can work longer between charges. More importantly, light weight battery means you dont need to be equipped with as much weight when using so you will feel less tired during handling.Today's high quality 48V batteries have enough power to drive an impact wrench with over 60Nm maximum output torque--and all that energy is stored right in them for when you need it. So users can hit the toughest of materials without even breaking a sweat all that easily. Conveniently, it also means taking down rock and concrete walls which otherwise could not be managed with ordinary hand tools are a cinch. What's more, no power cable offers unparalleled maneuverability and ease, effectively eliminating the accidents that might arise from loose wires on-site. People can handle it as they need shape it.My final reason is its lightweight handheld style. You will not get any wrist, forearm or other strain; and can keep on plugging away at any task without feeling fatigued from having to lift up so much weight for long periods of time. As a good, sturdy and efficient tool is required by people using electric power tools-especially those who make a living with them.
