How to choose a good electric drill, the difference between an electric hammer percussion drill and

An electric drill is a drilling machine that uses electricity as a power tool. It is a conventional product in power tools, and it is also the most demanded power tool products. Electric drills are only available in a rotating mode and are particularly suitable for drilling holes in materials that require very little force, such as cork, metal, brick, tile, etc.

The electric drill simply relies on the motor to drive the transmission gear to increase the rotation force of the drill bit, so that the drill bit does scraping on metal, wood and other materials.

Impact drills rely on rotation and impact to work, and can be used on natural stone or concrete. When the percussion drill is working, there is an adjustment knob at the drill bit chuck, which can be adjusted in two ways: ordinary hand drill and percussion drill. However, the impact drill uses the gears on the inner shaft to jump out of each other to achieve the impact effect, and the impact force is far less than that of the electric hammer.

It can also drill reinforced concrete, but it is not very effective.

Electric hammer is a type of electric drill, mainly used in concrete. Floor. Drill holes in brick walls and stone.

Specializing in wall, concrete, stone punching, as well as multi-functional electric hammer, adjusted to the appropriate position with the appropriate drill bit can replace the ordinary electric drill, electric pickaxe use. The electric hammer uses the bottom motor to drive two sets of gear structures, one to realize it drilling, and the other set to drive the piston, just like the hydraulic stroke of the engine, producing a strong impact force, accompanied by the effect of drilling. Strength can split stones into gold.

Electric drills can't hit walls! If you want to hit the wall, you need at least a percussion drill, and it is better to buy an electric hammer! Of course, you can use an electric drill to hit the wall, but the electric drill is useless!

If you buy an off-the-shelf drill, maybe it's a one-off! The impact drill is almost the same as that of the electric drill, the impact drill is to add a gear to the electric drill, and the others are almost the same! Why not buy a percussion drill!

There are also current percussion drills and electric drills that have forward and reverse rotation, which can be used to screw up! There are very few without forward and reverse drilling function! For home use, it is recommended to use a percussion drill!

I think if you drill wood, or drill holes in walls and bricks, small and shallow, and ensure the regularity of the holes, you can use an ordinary electric drill; If you drill a large and deep hole, you have to use a percussion drill.

Hello. If you don't often use an electric drill, it is recommended that you buy one without impact, which only plays a labor-saving role, and it is actually used for long-term use of electric drills. As long as the ordinary electric drill is practical and proper, it will not destroy the drill bit, it is recommended that you use an ordinary electric drill to expose the drill bit a little shorter, about 1 2 cm on the line.

If the depth is not enough, you can adjust the length of the drill bit. Don't be afraid of trouble, you don't use it often anyway, in order to save you a little money, if you don't think the impact drill is expensive, then you can choose the impact drill. Save effort and hassle. Forget to adopt.

Things are not afraid of many functions, maybe somewhere to use them! Like people, it's too late to buy it when you use it.

The hammering can only be used when the hole is opened, and it can be hammered with a special concrete drill bit, and the effect is average. You can use a triangular drill bit to open the tiles, pour some water at the highest speed, and you can also hit the concrete if the hole is not deep. An electric drill with impact will be a little heavier, and the gear structure will be a little more complicated.

It's a little more expensive, and everything else is the same.

Electric bricks are more suitable for home use, and they are suitable for electric bricks to punch holes and screws to assemble furniture.

Electric hammers and impact turns, which are mostly used for decoration, are decorated by wall holes, and are basically not used.

Depending on what you do at home, you must drill the wall to drill the impact drill. To drill screws, you need to use an electric drill.

The differences are as follows: electric drills, electric hammers, and percussion drills are all used to punch holes, electric hammers are generally used to drill holes in concrete and other relatively hard objects, and the drill bit is alloy steel, and at the same time of drilling, it has the function of a hammer. Electric drills are used to drill holes in relatively ductile objects, and the drill bits are generally steel.

The percussion drill has the functions of electric hammer and electric drill, which can be used as both electric hammer and electric drill. There are also two types of drill bits.
