CORDLESS Drill machines are an indispensable part of maintenance and construction tools. Whether used by a professional or an ordinary person drill machines to consider an essential tool in every toolbelt. Drill machines do need even for every day house maintenance jobs as well as for DIY furniture and the like. This is a type of power tool almost everyone should be handy with.
Because it comes to use a lot of times in even a regular person’s life. Ranging from domestic woodwork and maintenance to industrial woodwork, metalwork, and construction. The significance of drill machines cannot imply to ignore. Its applications are numerous. And its classification is hence base on the type of application. The most basic type of classification of drills is Corded and Cordless Drills.
These are the types of drills that are to directly connect to a power source such as electricity. Due to it, they are not likely to use everywhere. A constant supply of electricity is a must for the usage of a corded drill but due to their direct connection with electricity. These types of drills are more powerful and durable than other types of drills.
Due to their vast uses, these types of drills come with various features. However, its components with day-to-day upgrades enhance, modify and ease the use of the machine. For example, for better ease and comfort different types of grips are available for a firm or comfortable fitting. They can be set at various speeds. And they can also use external accessories to enhance their use. Due to the different features their durability efficiency and comfort increase making them economically good. The chord helps in giving maximum input energy. And, thus, maximizes the power and speed of the drill which makes these drills the most powerful.
The main components or parts that make up the functionality of a drill dictate its working efficiency as well as its weight and design. There are a variety of different types of corded drills present which consist of various components with different functionalities. Following are the different components present in a corded drill that provide a variety in their functionalities for different applications:
Length of Cord/Wire:
The main component of a corded drill is very obviously its cord or connecting wire. Now the length of the cord plays a huge part in the applications the corded drill would use for. If the length is not suitable it would be difficult to reach far places or into angles and corners. While, if the length were too long, it would prove to be a hindrance and a safety issue for users. Hence, a variety of different length corded drills is present which can select based on their applications. Longer wired drills are to select for getting to specific targets and angles.
Apart from a suitable length for a cord, the material of the cord plays a role in the working efficiency of a drill. How? The material’s flexibility decides if the cord can stretch and be taken to specific points. Moreover, the material also dictates the quality of the wire and causes safety issues.
Chucks are the main components used in a drill. Because it dictates the different types of functions that can perform by the drill. Also, the accessories to add to the chuck perform most of the operation. Traditionally, corded drills have chucks with keys, which are used to add and replace the accessories used. However, keyless chucks for corded drills are available as well.
Control of Speed:
Different models of corded drills offer different alternatives to control the speed and power of a drill. Control of speed and power is important to control the size and accuracy of the drilled holes.
Drill bits can rotate in two directions, clockwise, and anti-clockwise. The presence of a direction switch provides the ease of switching the direction of rotation and hence helps in loosening and tightening screws.
Benefits of cordless drills
Corded drills have a truckload of benefits. The most important factor in their speed and power comes from its big diameter saw which not only cuts through tough timber and wood but is also used for day-to-day household activities.
The efficient plug-and-play functionality allows the user more maneuverability and thus restrictions for movements are very less, unlike many other saws that restrict movement.
The small size usage also offers another advantage with a cost that it is much cheaper than other drills because a lot of expensive items such as batteries and other things are avoided due to the cord and its compact size is smaller, so the cost greatly decreases.
In terms of power,
the corded drills have more power due to their direct connection with the energy source and thus some drawbacks occur too such as their storing problems and due to the power, it doesn’t have the same precision and is not beginner-friendly.
As these drills have a huge power it leads to another drawback which is the precision the more powerful the drill the harder it will be for the user to precisely point it at the appropriate location and thus decrease the drill’s precision and accuracy.
Different types of corded drills exist for different functions, some main ones are as follows:
- Basic Drill: A multi-functional drill that is preferred for almost every time application, is highly efficient and powerful.
- Hammer Drill: This type is preferred for harder materials such as stone or concrete and is, therefore, heavier and more expensive.
- Rotary Drill: This type of corded drill is preferred for heavy-duty work.
- Angle Drill: Angle drill is preferred for drilling at a particular angle especially to reach corners and nooks. This type is usually used by electricians and plumbers.
These drills are relatively much more popular due to their innovative design and their ease of use. They do not require a direct power source such as being connected to a socket directly instead single or multiple batteries are used for power whose charging depends upon the speed of use and the capacity of the battery itself. Most of the drills usually have a charging time of 2 hours approximately if used at a moderate speed.
Features Cardless drill:
Although it lacks power due to its drawback in power it provides better precision and accuracy and has many other benefits. For example, it has an ergonomic handle. It also has a variable speed setting and can be used on different types of materials with different speeds and thus enhances the machine’s and the user’s ability to be more careful and efficient when it comes to doing difficult jobs.
It has a work-light installed within the tool which helps the device be more user friendly and efficient.
Due to the device being cordless it is more portable and easier to carry and thus also helps in storing the drill. Various grips and other accessories are also available for these devices too and it comes in 4 types. The built-in battery is used as a power source for these drills which is re-chargeable.
Components of Cordless Drill.
The elements in a cordless drill make up the total weight of the machinery. Moreover, the different options provide different types of functions for each specific model. Cordless drills consist of the following components and options available for different applications do explain below.
As the cordless drills need an energy source because of their direct disconnection with the socket batteries are essential for the working of cordless drills. There are mainly two types of batteries which are to use for this purpose.
Nickel Cadmium battery and Lithium-ion batteries
are the most usable batteries for Cordless Drills. There is, however, a slight drawback of using the Ni-Ca batteries as they are toxic and not much excitement friendly the new latter type was to introduce in newer models which are safe to use.
Chuck is to use to determine the functions you can do with your drill and defines the operations set by the drill and the accessories to attach to it. The width of the holes to drill is also determined by the standard of the chuck. Mostly the common models have a standard chuck the size of 10 MMS. Chuck has two types: the key-less chuck and the Key chuck. The key-less chuck is better as the changing of instruments can take place by hand, saving a lot of replacement time.
The clutch is an important component of the drill which is used to slow down the drill from over driving itself. This is done by decreasing the speed of the drill’s head. Clutch variations may occur for different models and the kind of work. Various tasks may also perform by changing the clutch settings to be suitable for the kind of work.
This is one of the most important components of the drill. The drill needs to allow the user to control the speed which can do by installing a small easy to use trigger on the grip. The user should have a firm grip on all speeds and needs to have complete control of the drill in case of any type of friction on any type of material.
The cordless drills have great mobility and as an added advantage in the form of a work light also installed within the drill. In case of any poor lighting conditions and in places where light reaches lesser than normal the work light ensures you’re never stuck while saving you. And your body from any kind of harm which may come from using other means to light the target up using a torch in the other hand or so.
Since cordless drills have less power because they are not directly connected to the energy supply. They provide more precision and accuracy. The power input and the output are to control by the user. So they provide better precision than corded drills.
It is storage-friendly. Because it has no wire or cord to store. And care for and can place anywhere suitable for its size.
The drill also comes in various speeds to do help in every field of work. And it can modify to the user’s need at the time being.
Due to it is not tied to a socket or switch it provides more mobility and convenience which allows you to drill at every location.
Although these drills are efficient and more user friendly and have great modifications. But these are not powerful as corded drills due to their lack of direct energy supply. The battery mostly runs out after 2 hours.
And it has limited energy only supplies limited power. So in terms of power, they fall behind corded drills. But in terms of mobility and efficiency such as the storage problems and other various household problems, they surpass the corded drills.
Although there are numerous different types of cordless drills to use these days for various purposes. The main types include:
- Drill Drivers: Usually prefer wood, plastic, and metalwork.
- Hammer Drills: This type is usually to prefer for concrete, stone, and brick materials as it has a built-in hammer, which provides extra load, but at the same time requires more power.
- Rotary Hammers: This type is similar to hammer drills. But it uses a pressure mechanism to work but is more weighted than hammer drills.
- Impact Drivers: These are to prefer for the most basic function of tightening and loosening screws. And other household operations and are the lightest out of all cordless drill types.
MAIN DIFFERENCES BETWEEN CORDED AND CORDLESS DRILLS:
The obvious difference between a corded and cordless drill is the presence and absence of the wire connecting to the power source, respectively. Secondly, the power source for a corded drill machine is the voltage supplied to an electric outlet either at homes or in industries. Whereas the cordless drills have batteries as their power source. Now, these being the obvious differences, there are some main distinguishing features for both types which are as follows:
As stated before, cordless drills run on batteries, usually 18-20V lithium batteries. Whereas corded drills have direct electricity. Their main power source and, therefore, has a much better power supply than the former.
Corded drills, due to having a wire attached to them are not portable and are difficult to manage. They are also in terms of safety, a hazard, as the wire would increase chances of tripping over it and causing an accident. Whereas cordless drill machines are to prefer especially for their portability, because of the lack of a wire or any attached external power source.
The durability or simply put, the life span of the cordless drill comparatively, is lower than that for a corded drill. This is again because of their different power sources. Although lithium batteries are highly advance and suitable for use during long periods of time, they get discharged or eventually run out and then must be charge or replace.
Since cordless drills have an internal electricity source in the form of batteries, they have more weight as compared to corded drill machines. The weight of the corded drills varies because of the different types of batteries used, for example, 4–8-volt batteries are sufficiently lightweight as compared to 12–18-volt batteries.
WHY ARE CORDED DRILLS MORE POWERFUL?
We know that corded drills are more powerful than cordless drills, but the question is, why exactly is that? Why exactly are corded drill machines more powerful than their cordless counterparts? The answer is simple and yet complex. The simple explanation is that the difference in power is due to the different sources of electricity to use i.e. since corded drills use direct electricity supply, about 110 volts of voltage supply which when compared with the cordless drills, having only an 18–20-volt supply, is a huge amount.
The more complex explanation
is that the power of these drills can calculate in the number of revolutions per minute, i.e., their speed and torque. The torque produced in advanced cordless drills also known as max-watts-out cordless drills is seriously impressive for its small-sized battery. However, the fact remains that corded drills have more power as compare to cordless drills, even after the countless novel technical advancements in cordless drills and their batteries.
Which one should you choose Cordless drill?
When selecting a drill, some factors should keep in mind to select the most suitable one according to your application or service. Although corded drills provide more power and durability cordless drills come with their own advantages, therefore, it is not a simple comparison to make. Therefore, the selection of either corded drill or cordless drill depends on the type of work they will ultimately have to be used for. The following factors should consider when selecting the type and model of drills:
The amount of power in a drill dictates the speed of the drill bit’s revolutions as well as the torque produced. It affects the main function of the drill and is hence, the most important factor to consider when choosing a drill. Therefore, the application or service for the drill should first observe. And then the drill it should choose. When a higher power service is required, corded drills should choose as mention before, that they have a higher power supply and hence prove to be more effective in high-power demand applications.
The size of a drill affects many factors including convenience, accuracy, and mobility. The size of a drill mainly depends on its components, i.e., the battery in case of a cordless drill. Since corded drills do not consist of batteries in their internal structure, they are relatively light-weight and smaller in size.
In terms of portability cordless drills are to prefer because they do not require a power source and consist of internal batteries. They are highly mobile and unlike corded drills to use in crooks and corners to reach far off places. When the service application comprises of far-away places where an electrical output is not available, cordless drills do utilize.
Having a good grip of a drill while functioning highly affects the accuracy, precision, and errors in the work performed. In this case, both types of drills come in a variety of different grip handles to increase the working efficiency of the drill. Choosing the correct type of grip handle for the drill plays a good role in determining the accuracy of the service results.
When choosing the correct drill for your service or use, you should know how much power the drill would require for the tasks in your mind for its application. The time for the project should take into consideration as well. In the case of corded drills, they can work effectively for hours on end, but there isn’t an electric outlet present at every project site. Therefore, when cordless drills are to utilize the power limit and battery time should consider beforehand. The selection of the correct drill with the suitable battery will thus depend on the project time and power requirement.
Although the accuracy of the holes does not matter in a lot of projects, there are still some high-profile projects that require the highest possible precision. The whole working phenomenon of some construction or machinery may highly depend on the accuracy of these holes and therefore, in such projects, the selection of a suitable drill becomes highly significant. Usually, cordless drills to prefer for high accuracy due to their low vibrating tendency.
Of course, another very important factor to consider before selecting and purchasing a drill machine for your projects is the allocated budget. Usually, corded drills cost less than their cordless counterparts because of the presence of an extra component i.e., the battery in the latter choice.
Drills have been with us since the industrial revolution. They have helped shape our modernization just like the bolt and the nut. The choice of the drill depends upon the application for which it will use. For hard or dense material, a more powerful drill to use whereas for a durable and ductile material the more precise and accurate drill will use. In terms of power, the Corded-Drill far outmatches the cordless drill. It has raw power and can use for almost any to every material cut through timber wood. The lumber with great ease due to its humongous saw.
The cordless drill lacks power but has far greater precision and accuracy than the corded drill. Both the drills have their own unique purpose and have to shape our homes schools and construction techniques. The invention of a drill has saved countless man-hours and has to help the labor to be more efficient speedy as they are reliable. Drills have been a building block in the construction tree and can never replace.
