Q:How big is the screw hole at the back of the torch chuck? Is it a rebound?

Usually around M5 or M6.If the chuck is to be assembled, stop the spindle from turning, and some have a rectangular edge that clamps the parallel edge with a thin, corresponding opening.

Q:Why is it that the motor of the drill has a buzz when it touches the switch lightly? It is not like the sound made by the mechanical structure. Is it the sound of the current?

The first step is to start with the starting principle of the motor. When the motor starts, there is a response time. Not to say that a power supply begins to rotate immediately. When the motor is not reached before starting speed, which transform magnetic field between the rotor and the stator of the motor, the magnetic field will transform energy if the energy is not driven from the rotor starts to rotate would be released by another, or fever, or noise, or magnetic leakage. Generally, what we can intuitively understand is sound and heat.

Q:Can you tell me what kind of good electric drill for household use? Impact drill or general electric drill good? Sometimes it's possible to hit the wall. How big is the power?

Impact drill work in a drill chuck adjustment knob, adjustable drills and impact drills in two ways. But the impact of drilling is the use of internal gear to achieve mutual beat of impact, but the impact is far less than the hammer. It can also drill steel and concrete, but the results are poor.

Q:When an electric drill is used, it does not change when it is erected

Drill power is not big, if the force is too large, the motor belt does not move, naturally not turn, will burn the motor.

Q:How to use the ordinary electric drill in drilling the tile hanging things?

An ordinary drill can, but must use an open bore with an alloy head (sold in a hardware store). First break to the center of the enamel drilling tools, crack a little on the line, convenient to locate drill drilling, without slipping on the tile, 6mm more than a dozen holes do not in place, leaving a little margin, according to the required aperture and then drill a hole will not be broken.

Q:How can a drill chuck without a connecting screw be mounted on an electric drill?

When equipped with positive and negative reverse switch and electronic speed regulating device, it can be used as electric screwdriver. Some models are equipped with rechargeable batteries, which can work normally within a certain period of time without external power supply. Special model: right angle drill --- suitable for use in narrow working space. (the nose of the electric drill is 90 degrees and the working space is reduced.)

Q:How to buy domestic electric drill

Look what you do. Hand drill: only drilling operations on metal plastic wood, electric drill without impact function, so it can not drill drill drill to drill: the impact of 2 /, including flat drill drill function, also has the function of shock, the ordinary brick concrete drilling (impact drill by internal 2 the impact of gear collision friction block impact) hit the wall slowly, but can not penetrate walls, mainly suitable for family wall drilling installation (such as small pendant paintings mirror small pendant, towel and so on) is not suitable for wall drilling engineering

Q:Can the starting machine be an electric drill?

If you want to directly mounted on the motor shaft of the boot drill chuck, the difficulty is very high, it is difficult to ensure the concentricity of the first drill, drill is not biased in a little, also because of low speed, can drill like wood,

Q:Why does the electric drill press the switch? Sometimes it turns, sometimes it doesn't turn. What's the reason?

The switch or power line is out of order and the contact is bad.The brush has been used for a long time and needs to be replaced.
