Some errors that cause the drill to work poorly

There are many reasons why the drill works poorly, but the following 5 reasons are common:

Drill motor problem

The motor is an important part of the drill structure. An unstable motor will cause the drill to operate inefficiently. Signs that the drill motor has a problem are that the motor sound is not continuous, or stops suddenly, there is smoke, and a burning smell coming from the machine.

If you encounter the above signs, you should bring the drill to a reputable warranty and maintenance center for inspection and repair.

Old drill bit

Drill bits are often used on hard materials such as wood, concrete, and metal, so they are easily worn out and no longer as sharp as they were originally. This will directly affect the drilling performance of the machine. If you find that the drill is not working properly, check the drill bit and prepare a spare drill bit in advance for replacement.

Carbon brushes are worn or damaged

The important component in the motor of the drill is the carbon brush. This is the part that maintains and supplies electricity to the rotor of the drill to rotate continuously. The working principle of the carbon brush is to use a spring to push the carbon head of the carbon brush to contact and slide on the commutator to help the current in the rotating part operate continuously.

Due to frequent operation, heat is generated, a lot of friction causes wear after a period of using the drill. To solve this problem, you should buy a new carbon brush to replace it. Replacing the carbon brush is not too difficult, so you can do it at home without having to repair it at the warranty center.

Engine dusty, dry oil

The drill is not maintained and cleaned after a period of operation, causing the drill to dry out, the engine to collect dust, and run weaker. Common signs of an uncleaned drill are that the machine heats up quickly, makes strange noises when operating, or has a burning smell when operating. To avoid this situation, you should clean the drill periodically, apply specialized oil to the bearings and gears, and perform maintenance every 3-6 months.

The switch is broken.

This is a part that works quite a lot when the drill user has to frequently press and release the trigger. Therefore, the switch often wears out and loosens when using the drill for a long time. The way to fix the switch error is quite simple, you replace the new switch or use glue to fill the worn area.

Notes when using a drill to ensure safety and efficiency

When using a drill, you should note the following points to ensure safety and efficiency:

Read the accompanying instructions carefully before use.
Choose the appropriate drill bit for each different material surface.
Store the drill, maintain it regularly, and keep it out of reach of children.
Use goggles and a mask to prevent dust and debris from flying in.
Prepare earplugs to reduce noise from the drill.
If the motor or drill components are damaged and make strange sounds, go to a reputable maintenance and repair center to fix the error.
