5 tips for you to use the drill correctly

The electric drill is one of the  equipment most used in works and each model has specific characteristics. To use correctly and safely, the first step is to carefully read the instruction manual of the purchased product.

It is worth noting that the more features the drill has, the more attention will be needed in its use. Also, the instrument needs to be chosen according to the type of work you intend to carry out.

There are several tools that are  similar in appearance and that perform different functions. Good examples are the industrial drill and the “hobby” — battery-powered, multi-purpose and with a quick coupling.

To eliminate doubts, we will present 5 tips for you to use the drill correctly . Read on and learn more!

1. Choose the ideal drill
There are several drill bits specifically designed for drilling in metal, wood and masonry. In this sense, it is necessary to know each model to make the correct choice.

Those with fine points are used for drilling wood, but some have three points. The central tip perfectly locates the center of the hole, preventing it from escaping from the starting point during work. The “flat” format drills are indicated for drilling ½ and ¾ holes.

Straight-cut, cylindrical shank twist drills are best suited for drilling metals. Video drills are ideal for drilling in concrete, brick and stone because they have a blunt and triangular head, piercing the surface due to impact (hammer position).

2. Know how to place the drill
When selecting and inserting the drill, it is critical that the drill is unplugged from the outlet. To insert it, just turn the mandrel (the base of the tip) so that the claws located on the tip are open and, thus, fit the drill to the bottom.

The chuck must be rotated again so that the bit is properly clamped. It is also necessary to consider that the mandrel has three holes around it.

Then, take the chuck wrench (T-shaped equipment), fit it one hole at a time, and tighten. This will ensure that the drill is 100% stuck to the drill, making it impossible for it to come out during use.

3. Perform a test to verify operation
Connect the drill to the outlet. With it lying on a smooth surface, turn it on to watch the drill work. It needs to rotate perfectly and without vibrations on the sides.

If you notice that the drill has lateral movements, it means that it is not secured correctly. So, go back to the previous tip and fit the piece again, watching the rotation to ensure that it worked.

4. Learn to hold the drill correctly
With the hand that you do most activities, hold the handle where the trigger is. This same hand will be responsible for activating the drill, pressing the trigger that makes the engine work.

The other hand is in a U-shape, supporting the front of the machine base. During the process, be careful not to close all the equipment's air vents.

In this sense, the drill support must be fitted and, with the hand that uses the least, hold it. With the other hand in the shape of a C, snap it into the back of the equipment and see if the little finger reaches the trigger button. Therefore, you must apply force in the direction of the drill to facilitate the hole.

• Extra safety equipment
• glove: only needs to be used on the hand that controls the trigger, as the hand that is close to the engine can pull some loose line from the glove;
• mask: protects the nasal passages from dust that comes out of the wall;
• ear protector: reduces the high noise produced by the machine, allowing greater concentration;
• goggles: prevents the eyes from contacting the dust released into the environment.

5. Define the location before drilling
With the location selected for the hole, fit the drill following the safety and use instructions that we presented in the previous topics. Furthermore, it is necessary to tap the drill so that it fits into the wall.

Ideally, choose the non-impact mode to start the hole and then switch to the correct or hammer mode, ending with a deeper hole. Practice brings about perfection and saves you from having to call someone to help.

Difference between hammer and drill
It is important to know the difference between an impact drill and a hammer to ensure they are used correctly.

Hammer drill
This model is ideal for works and renovations. In addition to working with rotation (turning), it also features the hammer function, which, in addition to turning, applies an extra force that helps in drilling. This function helps drill holes in surfaces such as concrete, masonry and stone.

There are types of drills that have a quick change button, which can switch between impact and rotation function. Models that contain this option are very advantageous as they can be used for simpler services.

It is possible, for example, to drill holes in less resistant surfaces (wood, conventional masonry and metal). When the user decides to carry out tasks a little heavier, just switch to the impact function.

hammer
It is also known as a demolition hammer. Widely applied in Civil Construction, it is a crusher model that serves to drill and break higher strength concrete, demolish columns, floors, beams, open gutters for the passage of pipes, drill asphalt concrete, among other functions.

Therefore, major renovations and even small changes to improve the home often require electrical equipment  that is often not part of the Basic Tool Kit of the common citizen or small contractor.

In this context, the ideal is to borrow the machine or buy something that, in addition to being expensive, can be used a few times. Thus, renting the drill is more advantageous, since the consumer is free from possible setbacks, purchase expenses and maintenance expenses .
