Electric drill type 1 Wireless handheld electric drill
The drill direction can be selected on the body of the handheld electric drill, with the button arrows backward being reversed (counterclockwise) and the button arrows turning forward (clockwise).
The drilling speed can be adjusted above the electric drill body.
The rotary circle of the drill head adjusts the drill torque. Torque can control the drill bit force to prevent drilling too deep, when the number on the knob is larger, the greater the force when the electric drill rotates, and the drill bit will not stop due to external force when rotating to the drill bit symbol.
It is generally relatively safe to use a power drill when turning the knob to 13-15.
The speed of the drill can be adjusted by pulling the trigger with different forces.
A spare drill bit can be placed in front of the base of the handheld electric drill.
Wireless handheld electric drills are generally used for drilling, and when used, fix the object that needs to be punched, hold the electric drill and pull the electric drill trigger.
Electric drill type two Impact drill
The impact drill has more force and the drill bit is a slot design that does not need to be rotated and fixed, if you want to remove the drill bit, simply pull open the sleeve.
Impact drills are mainly used to drill screws and make holes in wood. When using, just fix the plank, fix the nail with the drill bit, pull the trigger and press down.
Electric drill type three Small impact drill
Also suitable for women, the compact impact drills are lightweight and can be used by simply pressing down.
To pull out a nail, simply press the nail with an electric drill by toggling the directional button.
When removing the screw with an electric drill, do not touch the screw with your hand due to the high friction temperature.
Electric drill type four Wired electric drill
The power of the wired electric drill is larger for larger engineering use.
The drill or mixing bit can be fixed by twisting the fixed torsion wheel of the electric drill.
The above is the simple use of four common electric drills, for the use of electric drills, which can make perfect, remember to pay attention to their own safety when using, when hitting the wall, the drill bit should not be crooked, the crooked drill bit may be broken.
Some drill bits use and precautions:
Common questions
Q: What objects are impact drills used to drill?
A: Brick wall, concrete, ceiling, cement, rock, etc. (electric drill must open the impact function, concrete needs to use a better drill bit)
Q: What objects are twist drill bits used for drilling?
A: Steel, aluminum containing gold, stainless steel, plastic, composite panel, wood, etc. (electric drill turns off the impact function, drilling thick metal needs to use a better drill bit)
Q: What objects are triangular drill bits used for drilling?
A: Triangle drill bit, also known as porcelain drill, is generally used for tile drilling, if necessary, water is added for cooling, often used in bathrooms, open rooms and other wall tile drilling (electric shutdown impact function}
Q: What kind of objects are woodworking drills used to drill?
A: Woodworking drill bit for wood drilling (electric drill closing impact function)
Q: When the machine is working, there are sparks inside the body and there is a burning smell of plastic, is it a quality problem?
A: The friction between the motor and the carbon brush will inevitably produce sparks, not caused by electric current, no safety question, due to the new machine, the smell will disappear after a long time of use.
Q: Will the machine be hot when working, will it affect the use?
A: The heat is more obvious during high elasticity operation, because the motor generates high heat when the machine load is working, which is a normal phenomenon that does not affect the use.
Q: Why can't the wall go in, hit the concrete wall so hard, there is no impact function?
A: First of all, make sure that you use impact drill bits, operating specifications, concrete hardness is high, need to cooperate with better drill bits, the machine itself has no problem.
Q: The drill bit is broken when drilling in metal, is the drill bit too bad?
A: The twist drill bit has high hardness and is very harsh, and it must be vertically balanced with force, and a slight deviation is likely to break.
