A corded drill needs considerable power. While it is lighter than a cordless variant, it provides comparable functionality. The amp rating of a corded drill indicates its power. A constant power source translates into increased runtime since there is no need to stop replenishing the battery. The cable, on the other hand, does limit movement. A corded drill may need an extension cord depending on the distance between your work area and a power outlet. Keep reading for more information.
Certain skills are required for certain jobs, while others merely make the job simpler. Consider the following when selecting a portable power drill:
Drills are offered in the following sizes: 1/4-inch, 3/8-inch, and 1/2-inch. These dimensions relate to the drill chuck’s size — the portion that holds the bit — and reflect the drill’s maximum bit shank size. For a light-duty drill driver, a 1/4-inch chuck is adequate. A 3/8-inch drill takes a broad variety of bits, making it useful for a variety of household chores. A 1/2-inch drill is suitable for more demanding tasks.
Speed: A variable-speed drill with an adjustable clutch enables you to drill a range of materials and bits. Drilling softwood, hardwood, metal, and stone all need varying amounts of torque, or rotating force. Difficult materials and bigger bits need slower speeds and more torque. With softer materials and smaller bits, higher speeds and less torque are advantageous. The drill trigger is used to regulate the speed. The clutch is adjusted to the appropriate torque level. A correctly set clutch prevents you from driving a screw too deeply and minimises the risk of stripping or breaking a screw head. Drills equipped with a gearing switch enable you to choose between low speed and high torque and high speed and low torque.
While some drills have keyed chucks that need a tool to tighten or loosen, many drills feature keyless chucks that you can tighten or loosen by hand. If you often switch between drill and driver bits, a keyless chuck makes the work faster and easier, especially if the chuck can be adjusted with one hand.
Additional Features of a Power Drill
A brushless motor is very efficient, which results in increased runtime, increased power, increased durability, and less maintenance. Additionally, a drill powered by a brushless motor will be lighter and quieter. For more information, keep reading.
Another way to describe a drill’s power capacity is via its power output. A units-watts-out (UWO) value is used to describe the output as a function of both speed and torque.
- A built-in light illuminates the area in which you are drilling or driving.
- A built-in level enables more precise drilling and installation of fasteners.
- With an adjustable side handle, you can drill with more stability and control.
- Cases, extra batteries, and drill and driver bit sets are all examples of accessories. When looking for a cordless drill, check to see whether it has a charger. Take note that bare-tool drills do not include batteries or chargers.
