The use of rotary drill in various industries, especially in the construction industry, is very high. This drill is used to connect fittings to different surfaces. If you want to install lamps and lighting devices on the wall or ceiling, you should know how to use a rotary drill to make your work easier. This drill is also used for cabling in the walls.
The shape of the rotary drill
What is the shape of a rotary drill?
The rotary drill is a hollow cylinder with teeth on its edges. The application of the rotary drill is determined by closing the drill. With the help of a drill, holes and clean cuts are formed on the surfaces. But you should know that the cylindrical shape of this drill causes the drilling depth to be limited. For this reason, rotary drills are available in different sizes and shapes, so you can buy and use them according to your needs.
The body of the turbines is made of steel. Only the edges are made of other alloys. The metal body or cylinder of the rotor is installed on the axis. The teeth on the walls improve the use of the rotary drill. These serrations prevent chips and dust from clogging the drill bit.

Different types of teeth in the application of rotary drill
The use of the rotary drill is determined by the shape of the teeth on it. The desired drill is installed on the drill. Then, by turning on the torque drill, it rotates rapidly and the desired surface is drilled. In the following, we will learn about different types of teeth.
saw tooth
The teeth of this drill model have an angle of 60 degrees. This angle increases penetration and creates better and smoother cuts. The use of a rotary drill with saw teeth is to cut wood, plastic and soft metals.
Rotary drill teeth
Square edge or round edge
Drills whose edges are round or square, teeth are wide and help to grind surfaces more. Don’t expect powerful cuts with this drill. But it does the job of payment in the best way. Square or round drill bits are mostly used for cutting bricks, tiles and stones.
Blade cover
You cannot use a rotary drill to cut work on all surfaces. For this reason, you have to prepare dust collectors with different coatings. Usually, the coating on the blades is made of tungsten carbide. If you want to use a rotary drill for grinding surfaces, it is better if the blades have a diamond coating.

The role of the axis in the use of rotary drill
The axis plays an important role in the application of the rotary drill. The axles usually hold the different components of the drill together. One of the important tasks of the axis in the rotary drill is the connection between the drill and the drill. The axes are usually located on the drill. But if you want to buy them individually, you should pay attention to the dimensions and model at the time of purchase. The axes are sometimes in the form of a spring, which in this case is compressed during drilling and pushes the chips out of the hole.
Rotary drill axis
Types of axes
Fixed axis: If you want a drill with a certain size and you don’t need to change the size of the drills, the rotary drill with a fixed axis is suitable for you. With these drills, you don’t lose time and you can easily do cutting work.
Movable axes: Movable axes are used for blades of different sizes. If you need to change the blades while working with drills, it is better to use the moving axis to speed up the work. With this, you can easily adjust and replace the axles.
Small axis: these rotors have a rod length of 8.7 mm. The diameter of the blades in these grinders is 14 to 30 mm.
Big axis: the length of the rod in these axes is 11.1 mm. The blade diameter of these turbines is 32 to 210 mm.
The use of a guide drill in all types of grinders
The guide drill is located in the middle of the rotary drill. The main job of the guide drill is to hold the drill and prevent it from vibrating on the work surface. The guide drill marks the center of the desired circle and fixes the tip of the drill on the work. The other end of the guide drill goes into the three systems and the rotary drill is fixed inside the drill.

Advantages of using a rotary drill
One of the advantages of using a rotary drill is the ease of doing things and creating a circular hole. If you don’t want to use this drill, you must first cut the central part of the circle with a small drill. Then expand it with larger drills until you reach the desired circle. This takes a lot of time and energy. Do the same with a rotary drill in less time and more accurately. The bigger the circle you want to make, the easier it will be with the rotary drill.
Among the other advantages of the rotary drill, we can mention the reduction of power and energy consumption. The walls of the drill are thin and create little friction with the desired surface. This causes a small force to enter the drill for drilling. In this case, both the life of the drill is increased and the user uses little force for drilling. Also, you have created a lot of holes in a short period of time.
Due to the availability of different sizes and diameters, the flexibility of the rotary drill has made its applications popular, especially in the industries that deal with wood.

What is the material of the rotary drill?
The material of the blades of the rotary drill is different and the type of the blades determines the use of the rotary drill. In the following, we will learn about different types of rotary drill.
Carbon steel blade
From
This type of blade is widely used in domestic applications. Because it has the ability to cut low-density and non-dense materials such as wood, plastic and plaster.
Bimetal blade
These blades have more power and strength than carbon steel blades. You can safely use bimetal blades for heavy and long-term work. This model of grinders has steel teeth that have a high speed in drilling. The operator can change the cutting speed according to the need. The application of bimetal or bimetallic rotary drill is suitable for high density and hard surfaces such as hardwood, aluminum, zinc and copper. The maximum cut you can make with this drill is 42.5 mm.
Tungsten carbide blade
Drills with this material increase the speed of drilling. For this reason, you can continuously work with the drill and create many holes. The most common use of this drill is for industrial work. You can cut wood, plastic and all kinds of metals with a tungsten drill.
Diamond tipped blade
Diamond coating is used a lot to strengthen the blades. With the diamond coating, high heat and wear with the surface will not damage the blades. The use of a rotary drill with a diamond head is suitable for drilling holes on tiles and ceramics. It is recommended to use water and coolants when working with this blade so that the temperature does not rise too much.

Advantages of using a rotary drill
Drill selection method
Choose the drill using the following methods so that your work is done quickly and with quality.
Determine the required circle size
First, you need to know the required size in order to select and adjust the right drill bit and install it on the drill. Don’t forget to use oil or coolants during cutting.
Choose the right axis
If you are using drills with adjustable axes, be careful to choose the right axis with the rotor. You should also be careful to match the axis with the three drill systems.
How to adjust the axis?
Once you have chosen the right axis, you need to connect it to the rotor. Turn the rotor until the shaft is completely tightened.
How to tighten the rotor?
After we have fixed the hub and the shaft on each other, it is time to tighten the hub on the drill. For this, it is enough to fasten the end part of the axis on three drill systems.
Fixing the axle on three systems
Twist the three systems to a certain extent so that the axis is firmly inside it.
Safety tips when using a rotary drill
The use of a rotary drill is useful and effective for you when, in addition to using it correctly, you observe safety measures. You must use special glasses, safety gloves and ear protection. Use a drill with a protective handle to drill metal and hard surfaces.
