Q:Can an electric drill be changed into an impact drill?

Can not. If it is only the rotation without impact of the ordinary electric drill, and it is only when the rotation torque, so if to drill cement wall, caught in the impact on an electric hand drill drill, as determined by the characteristics of this kind of drill, does not have the "cutting", and has been in the cement friction. Can not rely on the impact to the loosening of the cement powder ash, cut off or vibration.

Q:What do you mean by pit drills?

Q:Can a torch drill against a wall?

In fact, mainly to see the drill bit, drill the strict requirements, only small drill can plug up what. The drill needs an alloy head, otherwise it burns easily.

Q:Is it necessary to use an electric drill or an impact drill to make holes in the wall?

Advise you not to do it yourself, because there are many kinds of building walls, can you make holes, use tools to make holes, and how to make holes, they are not such amateurs as you can operate.For example, the shear wall is a reinforced concrete wall. It is important to consider that the shear walls cannot be broken. Aerated concrete wall, hollow brick wall, that is, a hole is not good to install devices hanging objects

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 electric drills do not use brushless motors?

The second is the torque problem. Although brushless motors have the advantages of long life and low noise efficiency, these advantages are not useful in electric drills. It is limited by the weaker magnetic force of the permanent magnet, and the brushless motor can not produce large torque, which is very fatal. Because an electric drill requires great torque to overcome the resistance of the drill.

Q:Wall drilling, in addition to using an electric drill, there is nothing simple, easy to operate the way no?

That depends on what you are doing, and if you hang anything lighter, you can use cement nails, and a bit heavier hanging kit, it is best to electric drill, and the other will damage your home wall.

Q:Is the higher the voltage of the rechargeable flashlight?

When the output power of rechargeable power drill is the same, the higher the voltage, the smaller the rated current, because the power is equal to the product of the voltage and current. For example, long distance power transmission is the use of high voltage to reduce the delivery of electricity, although the high voltage line is thin, but it can deliver a lot of power.

Q:What about a charger without a charger?

The ordinary 12 volt output transformer can not be charged after rectification. This voltage is too low to charge electricity, and can not charge directly from the output transformer sub pole connection. The output of the pole is alternating current.

Q:What's the difference between an electric screwdriver and an electric drill?
