Hopefully, it will be helpful for you to decide which product – corded drill or cordless electric drill – suits you best!

Power Tools Buying Guide

Before you invest in any drill, it is necessary to know a few basics about it and how it works. This information will help you get a product that best suits your needs. Let’s start by examining various aspects of electric drills.

What is a Corded  Drill?

Dewalt Corded Drill

A corded drill comes with a powerful motor that is connected to a power source by an electric cable. The motor then turns the drill bit or screwdriver bit when you activate the trigger. The electric motors that run corded drills draw their power in their amperage rating. A typical corded drill can have a motor with a rating of 5 to 10 amps. The higher the amperage, the more torque the drill produces. 

It is also important to mention that corded drills are more powerful than their cordless counterparts. They are also lighter, and therefore fatigue is not a significant factor when working with these drills. However, they can inconvenience you because you can only work near a power source depending on the length of its cord. They are also noisy and, therefore, you may need here protection when using heavy-duty corded drills.

What is a Cordless Electric Drill?

Ryobi cordless electric drill

A cordless drill does not have a cord. Unlike a corded drill, it features a motor that is powered by a battery. Most brands rely on lithium-ion batteries which have more power capacity than ordinary batteries. Unlike corded drills that rely on motor amperage, the power in cordless drills depends on the battery voltage. Drills that come with high voltage batteries deliver more torque, which is the turning power applied on the drill bits. 

Some of the powerful cordless drills support 18 to 20 volts batteries. However, these batteries produce less power compared to the motors in corded drills. This feature limits most cordless drills to light-duty tasks. When it comes to size, cordless drills are bulkier since they have to compensate for the battery housing. This design makes them heavier and fatigue can be a factor when working with these drills.

Another advantage of cordless drills is that they offer you the convenience of working from anywhere without worry about a power source or the limitation of an electrical cord. This flexibility allows you to work in tight spaces with ease. These drills are also less noisy compared to corded ones and therefore make your working environment more comfortable.

Types of Drills

Corded and cordless drills have some design similarities that determine how they function and therefore their most suitable applications. Here are some of the most popular drill types.

Electric Screwdrivers

As the name suggests, these are power screwdrivers are limited to lightweight tasks such as tightening or loosening screws in tight places in tight spaces. They come in small, compact, and cordless designs. Unfortunately, they do not have enough power to drill holes.

Drill Drivers

Drill drivers are more versatile than power screwdrivers in that they provide you with enough power to drill holes through wood and metal surfaces. You can also use them to tighten and loosen screws.  If you are looking to put up shelves in your home or do similar jobs, then a drill driver is your best bet.

Combi Drills

These drills function the same way as drill drivers, what makes them different is that they have a hammering action that makes them ideal for masonry applications. Therefore if you wish to drill holes through brick surfaces such as walls, then go for a combi drill.  

Impact Drivers

Impact drivers come in more compact and lightweight designs. They are specially designed to produce more torque while reducing their impact on your wrist. This way, you can handle heavy tasks for longer with less fatigue. Impact drivers are most suitable for large projects that require repetitive screwdriving or drilling holes on metallic surfaces.

Hammer Drills

These drills are powerful, and ideal for drill holes through concrete and brick walls. It is common for hammer drills to have multiple torque settings. This way, you can regulate the power and keep the RPM low to allow for drilling while minimizing the damage to your surfaces. Unlike impact drills, they do not always have a reverse setting to loosen screws.

Slotted Drive System (SDS) Hammer Drills

The SDS hammer drills function like hammer drills. However, their design features a piston that fires the drill and pulls it back repeatedly drives the hammering action. This design results in increased efficiency while reducing friction and makes the SDS drills easy to work with. They use special drill bits to minimize cases of drill bit slipping. You will also need to use stronger bits that can withstand increased power from the SDS action.

How to Choose the Right Drill for you

Now that you know what corded and cordless drills are, let us examine what you need to look out for when choosing the best power drill for your needs.

Flexibility

When choosing an electric drill, it is important to consider the flexibility that comes with it. This will depend on the nature of your project. For instance, if you will be working from a workbench where you do not need to change your position now and then, then a corded drill can work for you. However, if you need to walk a lot, especially in a construction job, then a cordless drill is the best option. 

Power Source

As stated earlier, electric drills can run on either AC or DC power sources. Corded drills run AC motors. The Amps rating on these motors determines the amount of power they can deliver. The good thing with corded drills is that they have unlimited runtime as long as you have a reliable electricity connection.

 On the other hand, cordless models run on batteries. The best cordless drill models use lithium-ion batteries because they come in small and compact designs. They also take a short time to charge, have a longer shelf-life, as well a longer lifespan. Battery-powered drills allow you to work off-grid or during blackouts, albeit for a limited time because of their short runtime. However, you can extend their runtime by investing in electric drill sets with multiple battery packs.

Torque

The torque of a power drill is the amount of force it can produce to turn a drill bit, measured in inch-pounds. Generally, cordless drills with 12 to 20 volts batteries can produce enough torque for a wide range of applications. However, heavy-duty tasks such as masonry drilling and chiseling require more torque.   

Chuck Size

The size of the drill chuck determines the diameter of the drill/driver bit that the power tool can accommodate. If you are shopping for an electric drill for general applications, then a model with a 3/8″ chuck size is sufficient. However, if you are working on projects that require high torque, then go for a half-inch chuck size. 

It is also important to mention that drill chuck can be keyed or keyless. Keyed chucks are common with corded drills. These models require you to use a key to lock or loosen the chuck when changing bits. Keyless chucks on the other hand are common with cordless drills. You can easily change the bits with your hand in under 5 seconds.  

Type of Motor

Before purchasing a cordless drill, it is important to determine the type of motor it is running on. The motor could be brushed or brushless. Brushed motors come in large designs and can be heavy. 

However, they are cheaper and easy to repair. On the other hand, brushless motors are more efficient than their brushed counterparts and produce 30% more torque. They also provide longer runtime and have a longer life span. This way, they give you value for money in the long run. 

Their better power-to-weight ratio results in lighter drills, which result in less fatigue and improved work output. Therefore, if you are looking for a drill for occasional use, a brushed motor model could serve you well. However, for more demanding tasks, a brushless model is the ideal pick. 

Ergonomics

When choosing power drills, go for models that are comfortable and easy to use. For instance, rubberized handles are soft and provide a non-slip feature. This way, you have a firm grip on the drill for a stable and safe working experience. Other features such as variable speeds and clutch settings give you added flexibility when using powered drills. Models that come with magnetic trays, drill bit docks and LED lights make you more productive by saving you time. 

Weight

The weight of an electric drill affects your overall output, especially when working on a big project. Lightweight electric drills translate to less fatigue, thus allowing you to work longer hours.

Pricing

It is necessary to consider the pricing of power drills before purchasing one. Different models are priced differently depending on their features. Generally, you can get a good electric drill for a price of $30 to $100. However, do not focus on price but the features of the product. The idea is to get a drill that suits your needs.

Warranty

The best electric drill brands in the market provide consumers with warranties as a guarantee for the quality of their products. Most companies offer 2 to 3-year warranties for their electric drills. Make sure you observe the warranty terms and conditions for it to hold.

How to Use Drills Properly

When using power drills, it is advisable to read through the manufacturer’s manual. This document gives you an in-depth understanding of your and any special features that might come with it.

  1. Once you are ready, connect your drill to a power course and select a drill that is suitable for your application. This action will determine the outcome of your project. For instance, failure to use the right drill bit might split your wooden surface.
  2. Now loosen the chuck and put in the drill bit. If you are using a corded drill with a keyed chuck, use the key to secure the bit in place. Keyless chucks on cordless drills are easy to use. Just turn the chuck in the anticlockwise direction to open it up and then place the drill bit shank in the jaws of the chunk. Re-tighten the chunk by turning it in the clockwise direction.
  3. Confirm the drill settings, such as the desired speed to produce the right torque for the job. Also, confirm that the drill is set to run in the right direction. For example, if you wish to loosen some screws, you will need to set the drill to move in the counterclockwise direction. 
  4. Make sure that the materials you are working on are firmly held in place. For instance, if you are working on a workbench, secure the surface with clamps. If you are drilling holes on a piece of wood, leave some clearance to avoid drilling into the workbench. 
  5. Now drill the hole in the desired surface. Start by placing the tip of the drill on the surface at a reasonable angle. For instance, for straight-through drilling, hold the drill bit at a right angle to the surface. Now, use your finger to apply pressure on the trigger to start drilling. Once the drill bit has cut in the surface increase, the pressure on the trigger. This move will speed up the drilling.
  6. Examine the hole to confirm whether your desired bolt or rivet can fit in the hole. If the bolt is too large for the hole, use a slightly larger drill bit. Hopefully, the bolts will fit perfectly. Clean the workbench and remove any chips that might have accumulated on it. 

Drill Safety Tips

It is advisable to handle electric drills with a lot of care to avoid accidents. Here are infallible tips to help you operate your power drill safely.

Avoid Loose Clothing

When working with electric drills, it is advisable to avoid loose clothes as they can get entangled with the rotating part of the drill. If this happens, you can suffer serious injuries that could affect your daily life for a long time. To be on the safe side, avoid ties and long-sleeved shirts. You may also need to tie back your hair if it’s long.

Keep Your Working  Area Neat and Secure

Whether you are drilling holes or fastening screws, you need your working surface steady and secure. If it’s loosely held in place, it could shift and fall or hit you. The drill could also slip and land on your hand. Such accidents could cause damage to your property or lead to serious injuries.

Invest in Protective Gear

The drilling action of the drill could send metallic, concrete, or wood particles flying in the air without a warning. Such debris could find its way to your eyes. If this happens, you could suffer serious injuries. In this case, you need to invest in quality safety goggles to protect your eyes. Also, use fitting but comfortable gloves for your hands as well as a face mask to keep off dust.

Use Pilot Holes for Your Screws

Before driving screws into any surface, it is advisable to make drill pilot holes. The holes hold your screws in place and make sure that they drive straight. Pilot holes also prevent drills from slipping and eliminate the need to apply a lot of pressure on the tool.

Secure Your Drill Bit In Place

Before you use a power drill, insert the drill bit in the chuck and ensure that it is firmly and securely fixed in its place. Failure to do so could prevent you from drilling straight holes. You also risk the drill slipping and causing accidents.
