Shopping Guide: Everything you need to know about electric drills
There are many types of electric drills, so you should be aware of their many possible features before choosing one. It’s important that you know the tools well before you decide to buy one. Here’s a list of frequently asked questions from users, to answer any questions you may have and help you make a good purchase.
What is an electric drill exactly?
For starters, electric drills are very versatile tools. They are usually shaped like a pistol and have a trigger-shaped switch that activates the mechanism. Drills have a housing that covers the motor and the frame, this casing is usually made of reinforced plastic. The final part is the end piece called the “mandrel,” this part is on one end of the tool and it holds the drill bit.
Standard electric drills are for manual use, while the larger ones are held in columns. The latter are for professional use and are usually found in workshops. Their power varies greatly depending on the drill type; they range from 12 watts for battery drills to 1200 watts for column press drills. The average voltage offered in general use tools is around 600 watts of power.
How do electric drills actually work?
As their name would imply, they work with electricity, provided either by socket or by batteries. Electricity generates a movement in the motor bearings that rotate the mandrel and thus the drill bit. It is through this rotation that the material being worked on is perforated. Most drills have speed controls which will determine whether to generate more or less power depending on the material being worked.
What are the advantages of using electric drills both with cords and battery operated?
Which drills are better, with cords or with batteries? This is an important question that users of these types of tools often ask themselves. When it comes to choosing between the two types of electric drills, you need to know what you’re going to be using it for. Below is a list of the pros and cons of each type.
Electric drill – with cable
Electric drill – cordless
What is the difference between a traditional electric drill and a hammer drill?
Traditional electric drills function through their rotation movement. The motor bearings transfer movement to the drill and the drill penetrates the materials. This makes it possible to drill into different matter, such as wood and metal. This function does not work on hard surfaces such as concrete or rock.
Percussion (hammer or impact) drills, in addition to having the rotation movement, also exert percussion and impact. This movement is exerted from front to back repeatedly. This allows the material to be pounded. This movement is generated by two grooved discs that rotate in contact with each other, impacts are then transmitted to the drill bit.
To avoid accidents, what measures should be followed when using an electric drill?
Electric drills are very powerful tools. You must be careful when using them to avoid accidents and injuries. Misuse of the electric drill can cause bad injuries. After all, the drill bits are made to be sharp and very dangerous. In this section we will show you the safety guidelines for using an electric drill without any issues.
- Safety goggles: When drilling and hammering, metal or stone chips can jump out. Furthermore, some electric drills have internal brushes that can generate sparks. For these reasons, it is essential to protect the eyes from sparks and splinters with protective goggles.
- Gloves: Actually, it is not recommended to use gloves with electric drills. Gloves are often loose and the fabric can get caught in the drill bit causing some serious accidents. These types of incidents are common in workshops and should be prevented at all costs.
- Applied pressure: The drill has its own power, it penetrates the material at its own pace, make sure not force or push the tool. If the drill doesn’t penetrate, it is likely because the tool doesn’t have sufficient power. Don’t push it, if the drill bit snaps it can fly off and seriously hurt others.
- Overheating: This goes along the same lines as the previous point. Drills have their set power and should not be forced. If forced they can overheat and the engine will burn. If this happens, it will not only damage the electrical installation of the tool, it could also cause a fire.
- Materials: Do not use the electric drill on materials outside of its intended use. For example, if your drill doesn’t have a hammer, don’t use it on stone.
- Holding: The drill chuck must always be securely fastened. If the drill bit is loose and moves around, it can break and wound people.
In order to choose the best electric drill it’s important to pay attention to some criteria that will facilitate the purchasing decision. In this section we will go over every aspect you need to consider before buying a product. With this mini guide you’ll be able to adjust your search for a specific quality and price.
The criteria to consider before making your final decision are as follows:
- Safety stop
- Handle and accessories
The suitable power allowance of a conventional DIY drill, with cable, is typically between 500 W and 850 W. Beyond that, if used for small tasks that we need to perform around the home, it would be an oversized – this type of product is indicated only for professional use. The power provided by wireless drills are usually differentiated by the voltage in the batteries.
Drills with 18 V batteries will have more powerful motors. The power they deliver, in watts, usually does not reach 500 W.
For more power you have to resort to a larger budget and more professional models. Despite having lower power output, the only limitation of this type of drill is manifested when facing hard materials such as concrete.
This is a very important feature for user safety. The automatic brake causes the drill to stop rotating immediately as soon as you release the trigger. On models without this feature, the bushing continues to rotate until it stops naturally. This safety feature is standard in wireless tools, newer models are hard to find without it.
Handle and accessories
Drills usually have two types of designs: T-shaped and pistol-shaped. There are also angular and column drills. Angular drills are ideal for working in difficult places. Keep in mind these are tools of very a specific modality and we have not covered them in this guide. When it comes to handle, the most important thing is that it’s design is ergonomic and comfortable.
It is also greatly appreciated by users when the handle has added gripping, which some models include as a standard. Comfort is much appreciated when handling these tools for extended periods of time. Some drills can weigh more than two kilograms, keeping weight in mind comes in handy during jobs that require a lot of drilling. Trust us, your body will feel it. Another great extra feature is the safety stop.
Percussion – Impact
A powerful hammer drill with a cable can handle almost any surface, including the much dreaded concrete. They have toothed gears that are activated when the torque begins to experience difficulty. This transmits impact on the material, which facilitates the perforation of hard surfaces.
You can find hammer drills with cables and cordless, but for harder surfaces such as concrete, as well as hammer drills, they have to be powerful. Most wireless drills aren’t powerful enough to handle these tough materials. One drawback is that percussion drills are usually more expensive.
The best cable drills for DIY aficionados and professionals alike have multiple mechanical speeds or “gears” that control the machine’s speed and power. For example, for concrete it is convenient to use position “1” because, although it turns with less speed, it delivers more power and the impact is what does the job.
In addition to providing control over the engine torque, in some models you can select the chuck position depending on the tool. These can have between 10 and 30 positions. Other functions that can be selected are the specific job of the drill: screw, drill or hammer.
Did you know that wireless drills always have two mechanical speeds?
Battery-operated drills have less power. When their battery is drained you have to stop working until it is charged again. Some models incorporate an extra battery as an added feature, but this is not the standard. Some batteries have a fast-charge function, allowing you to have a full charge in less than sixty minutes.
Drill batteries are usually lithium ions. These modern batteries are lightweight and have longer life. Moreover, these don’t have the dreaded memory and battery loss effect, so they’ll always have the same capacity. Cheaper cell batteries don’t last as long, take longer to charge and do have the memory effect which depletes its life capacity over time.
Buying an electric drill is always a good choice. You can also do any do-it-yourself work with these versatile and easy-to-use tools. These items allow you to carry out all sorts of repairs and DIY projects in less time and with less effort. Keep in mind, you just have to take into account your needs and the materials you will be working with.
If you intend to buy an electric drill take into account the criteria we have presented in this article. As you may have seen in the last section of this article, materials, spare parts and safety are important things to consider, but so are the battery life and the value for your money. Make sure to take all factors into account when making your purchase!
