If you wish to drill large-diameter holes in masonry, select a corded drill with a low speed gear. To do this you will need a drill with hammer action. Sooner or later you will almost certainly need to drill into masonry. Battery sizes typically range from 12V to 20V. The higher the voltage rating is, the more powerful the drill. For most basic home DIY jobs, a 550 watt drill is adequate.Ĭordless drill power is measured in volts. A higher wattage is better for drilling masonry, while if drilling into plasterboard, a lower wattage will suffice. What’s more, you can use the same battery with other power tools from the same brand, helping to reduce the cost of buying lots of batteries.Ĭorded power drills are rated in watts, typically ranging from 450 watts for basic models to around 1500 watts for the more powerful hammer drills. This technology allows the battery to be fully charged quicker (often in less than 60 minutes) and holds more power for longer. However, the most powerful cordless tools are usually more expensive than their corded equivalents.Ĭordless drills are now powered by more efficient, rechargeable Lithium-ion battery.
A cordless drill will give greater mobility as you can take it anywhere without having to tow an extension cable behind you.
If you opt for a mains powered, corded drill, you will also need to use an extension lead. Corded drills are often lighter than their cordless cousins as there is no heavy battery pack.
