The drill, which is used for decorating living spaces, making renovation works and professional construction works, is a very useful tool. It is often used for drilling, screwdriving or hobby work on any floor. As in every product, there are varieties with different functions and areas of use in drill models. In other words, the model you will buy for a hobby and the model you will buy for a professional job should not have the same features. In this article, you can find everything you need to pay attention to when buying a drill.
The drill, which has a very wide usage area, is used to drill holes on hard surfaces or to expand the existing hole in different sizes. It has two different types as its working principle. These are impact drilling and rotary drilling methods. Rotary drilling method is mostly used in mining and drilling works. Impact drilling is the model used in living spaces, workshops, workplaces, in short, everywhere in daily life. Now let’s take a closer look at the information about the selection of drills.
What are the Drill Types?
If it is necessary to divide the drills into main groups, there are basically 4 types of drills. They are divided into groups according to both drilling styles and connection types.
- Impact drill: Used in hard areas such as concrete and masonry, the impact drill uses the energy generated by the collision of two discs in the drilling process. The biggest disadvantage is that it works at high volume. Also, some models are a little heavy.
- Drill without impact: The hammerless drill, which is quieter and more practical than impact models, works by transmitting the energy of the piston, which compresses the air, to the drill bit. Ideal for drilling or widening holes in relatively soft areas such as wood, metal, plastic. You can choose this model in areas such as professional use, housework, renovation and hobby.
- Corded drill: Apart from the working principles, the energy connection also divides the drills into different categories. The models that get their energy needs from the socket plugged into the plug are called wired. Many of the models that require high energy to operate are in this category.
- Cordless drill: This model, known as a cordless drill or a battery drill, works wherever you want without the need for an electrical connection thanks to its battery. In this way, it is very practical and useful. It also eliminates problems such as cable length. When buying, you need to pay attention to the battery capacity and life.
Considerations When Buying Drills
- The part holding the drill bit is called chuck. chuck; It has two options, keyed and keyless. On keyed models you need a wrench to change the bit. You cannot do any other tip change. On keyless models, you don’t need any keys. Therefore, it is a fact that keyless models are more practical.
- If you are going to use battery-powered models, you should pay attention to the Volt value, which expresses the power of the device. The higher the Volt value of a device, the greater the drilling power. Low Volt power will quickly end the battery life as it will consume a lot of energy in long operations. The model you will use for standard work at home must have a power of at least 10 Volts.
- If you prefer a wired model, this time you should look at the Watt power of the device. You need 500-800 Watts for a standard model that you will use for housework, and more than 900 Watts for more professional works and sanding.
- Another issue to be considered in battery-powered models is the amperage value. The higher the amperage, the longer the charging time. Therefore, if you want a long charging time, you should prefer high-amperage models.
- The turning power of the drill is expressed in terms of torque and speed. Models of 1300 rpm and above will work for you in housework. For more extensive processes, wooden and metal surfaces, devices with 3800 or more revolutions are required.
- Finally, it will be useful to research the brand, service network and spare parts supply capacity of the model you have chosen. In case of possible malfunctions, brands with a wide service network will help solve the problem quickly.
