How do I choose a drill?
Power: There are two values you'll need to keep an eye out for here: voltage and torque. The general rule of thumb is that a higher voltage means a more powerful drill. Most cordless drills today are 18V, although lower (7.2V) and higher (20V) options are available.

What is a corded drill?
A hand-held corded electric drill. A lightweight magnetic-mount drill. A drill or drilling machine is a tool primarily used for making round holes or driving fasteners. It is fitted with a bit, either a drill or driver, depending on application, secured by a chuck. Some powered drills also include a hammer function.
How does a hammer drill work?
The hammer action of a hammer drill is provided by two cam plates that make the chuck rapidly pulse forward and backward as the drill spins on its axis. This pulsing (hammering) action is measured in Blows Per Minute (BPM) with 10,000 or more BPMs being common. Because the combined mass of the chuck and bit is comparable to that of the body of the drill, the energy transfer is inefficient and can sometimes make it difficult for larger bits to penetrate harder materials such as poured concrete. A standard hammer drill accepts 6 mm (1/4 inch) and 13 mm (1/2 inch) drill bits. The operator experiences considerable vibration, and the cams are generally made from hardened steel to avoid them wearing out quickly. In practice, drills are restricted to standard masonry bits up to 13 mm (1/2 inch) in diameter. A typical application for a hammer drill is installing electrical boxes, conduit straps or shelves in concrete.
What is a rotary hammer drill?
The rotary hammer (also known as a rotary hammer drill, roto hammer drill or masonry drill) . Generally, standard chucks and drills are inadequate and chucks such as SDS and carbide drills that have been designed to withstand the percussive forces are used. A rotary hammer uses SDS or Spline Shank bits. These heavy bits are adept at pulverising the masonry and drill into this hard material with relative ease. Some styles of this tool are intended for masonry drilling only and the hammer action cannot be disengaged. Other styles allow the drill to be used without the hammer action for normal drilling, or hammering to be used without rotation for chiselling. In 1813 Richard Trevithick designed a steam-driven rotary drill, also the first drill to be powered by steam.
How many watts does a rotary hammer drill use?

Why buy a corded electric drill?
Although cordless drills have made great advances, you're still reliant on a battery when you use one. A corded electric drill works anywhere there's a power socket – and it works all day and night if you need it to. Performance doesn't deteriorate as it does with cordless drills, and torque is usually higher, too.
Electric drill power
Corded electric drill power is measured in amps. An entry-level model for light-duty DIY tasks will be rated for around three amps. At the other end of the scale, general-purpose drills of professional-grade quality are rated at up to nine amps.
Electric drill speed
When evaluating the speed of an electric drill, consider that maximum speed is less important than variable speed. If you have a small drill bit and want to make a 1/16-inch hole in a piece of aluminum, you need high speed. However, if you're using a 1/2-inch spade bit in wood, you need slower speed.
Electric drill chucks
There are two types of chuck: keyed (also called Jacobs) and keyless. Keyed chucks have been around since the invention of the electric drill. The use of a key allows you to apply more force to tighten the drill bit.
Other electric drill features
Weight: General-purpose corded electric drills weigh anywhere from three to six pounds. That’s not particularly bulky, but it could be a consideration for users with reduced hand or arm strength. It's worth checking the weight of a drill before you buy because high performance doesn't always mean a heavier drill.
Electric drill prices
If you’re in the market for a low-cost electric drill, you can find a good one from a trusted brand like BLACK + DECKER for $30 or less. We advise potential buyers to stick with known brands with a proven track record for durability and reliability.
Safety tips
Be careful with the cord or extension lead attached to your electric drill. To keep it out of the way, consider looping it over your shoulder.
Overview
A drill is a tool used for making round holes or driving fasteners. It is fitted with a bit, either a drill or driverchuck. with hand-operated types dramatically decreasing in popularity and cordless battery-powered ones proliferating.
Drills are commonly used in woodworking, metalworking, construction, machine tool fabrication, construction and utility projects. Specially designed versions are made for miniature applications.
History
Around 35,000 BC, Homo sapiens discovered the benefits of the application of rotary tools. This would have rudimentarily consisted of a pointed rock being spun between the hands to bore a hole through another material. This led to the hand drill, a smooth stick, that was sometimes attached to flint point, and was rubbed between the palms. This was used by many ancient civilizations around the world including the Mayans. The earliest perforated artifacts, such as bone,
Types
There are many types of drills: some are powered manually, others use electricity (electric drill) or compressed air (pneumatic drill) as the motive power, and a minority are driven by an internal combustion engine (for example, earth drilling augers). Drills with a percussive action (hammer drills) are mostly used in hard materials such as masonry (brick, concrete and stone) or rock. Drilling rigs are used to bore holes in the earth to obtain water or oil. Oil wells, water wells, or hole…
Surgical
Drills are used in surgery to remove or create holes in bone; specialties that use them include dentistry, orthopedic surgery and neurosurgery. The development of surgical drill technology has followed that of industrial drilling, including transitions to the use of lasers, endoscopy, use of advanced imaging technologies to guide drilling, and robotic drills.
Accessories
Drills are often used simply as motors to drive a variety of applications, in much the same way that tractors with generic PTOs are used to power ploughs, mowers, trailers, etc.
Accessories available for drills include:
• Screw-driving tips of various kinds - flathead, Philips, etc. for driving screws in or out
• Water pumps
Drill bits
Some of the main drill bit types are
• twist drill bits - a general urpose drill bit for making holes in wood, plastic, metals, concrete and more
• Counterbore Drill Bits - a drill bit used to enlarge existing holes
• Countersink Drill Bits - a drill bit to create a wide opening for a screw
Capacity
Drilling capacity indicates the maximum diameter a given power drill or drill press can produce in a certain material. It is essentially a proxy for the continuous torque the machine is capable of producing. Typically a given drill will have its capacity specified for different materials, i.e., 10mm for steel, 25mm for wood, etc.
For example, the maximum recommended capacities for the DeWalt DCD790 cordless drill for sp…
