How big are the electric drills with small dots below the percussion drills! How much is it?

Generally, household chucks can be selected below 13mm, ** generally between 100 and 200 yuanToo cheap is built in an underground factory, not durablePros:

**Cheap, disadvantages: generally not self-locking chuck, need to use the key to disassemble and assemble the drill bit, not very convenient. Low-grade products generally have no speed regulation and forward and reverse adjustment, and power supply is required when used, and there is basically no torque adjustment, and the function is relatively simple.

Then there is the use of a cordless electric drill is the use of rechargeable batteries, ranging from 24 volts, ** between 240-1000 yuan for families with about 200-300. All of them are self-locking chucks, with forward and reverse adjustment, manual control stepless speed regulation, and some have two mechanical speed adjustments, with torque adjustment, which can be used as electric screwdrivers, which is very convenient. The larger ones also have an impact function, but ** is also slightly higher, advantages:

Convenient, no need to hold a long power cord. Self-locking chuck, no need for a key. Powerful torque adjustment, easy to remove and assemble screws.

Stepless speed regulation, very convenient. Cons: Higher level.

The continuous working time is short, generally about one hour. The battery will die. Therefore, it is more suitable for families who are not very frequent.

The diameter of the domestic electric is about 18mm-20mm!! There are 120-150 yuan...

It is a 6 mm drill bit. During the pit digging operation, the drill bit rotates with the vertical shaft and moves axially at the same time. The soil is cut by the torque and axial forces of the drill bit and is loosened by the extrusion and centrifugal force of the working blades.

A flow of earth is formed against the pit wall, while it is lifted along the page to the surface. When the soil flow moves to the place where there is no pit wall block, the broken soil is thrown around the pit due to centrifugal force, and the pit digging process is completed.

Hello, glad to answer for you. There are many kinds of drill bit specifications, generally starting from millimeters, increasing millimeters with each rising gear, hand electric drills generally use straight shank drill bits, up to 13 mm, the main model of impact electric drill bits is mm, etc. Hope mine is helpful to you.

1.There are many specifications of hand drill twist bits, some are integers, and some are with decimals: such as

2. Wait, it should be based on your needs, and then according to the size of the drill chuck, if the chuck can only clamp below 6, the drill bit above 6 will not be used, if the chuck is greater than 13, of course, there are many specifications below mm13. 2.Percussion drill bits are fixed, only integers generally have:

These specifications. Larger than 32 should use a hole machine.

The smallest is 6 drill bits.

Hello dear I'm glad to answer for you: I'm your exclusive ** answer teacher, thank you for your patience. Your question: An electric drill is not a percussion drill; 1. The three major differences between percussion drills and electric drills 1. The working principle is different

The electric drill has a small capacity, which can drive the connecting rod drive, and also increases the power of the drill bit, which is easy to penetrate the object; Whereas, percussion drills are the same as electric drills when drilling, and when entering the punching mode, the impact force will be at the end of the drill bit and make it impact forward. 2. Different working modes: the electric drill only has a rotation mode, and the pure imitation drilling has two modes: rotation and impact.

Qinqin: What is recommended is the 35mm impact drill, how much power of the hammer is suitable, and the power of the rotary hammer can be recommended to use 1500w-3000w power. It should be determined according to the inner diameter and depth of the borehole. Usually come to Mengzhen stove, with the increase of power, the working capacity of the electric hammer is also correspondingly enhanced, which can save more time.

The power of the electric hammer is generally classified according to the size of the borehole, and there are often multiple grades such as 300w-1000w, 1500w-3000w, 4500w-8000w, 9000w-15000w, 18000w-25000w. Considering the 35mm percussion drilling, it is recommended to use the electric hammer with 1500w-3000w power, which can ensure low-frequency, high-strength, fast hole processing, and compact, unobstructed, without fragmentation and tearing, which has its own advantages in the field of hole processing, which can greatly improve the processing efficiency, precision and accuracy. In addition, the power of the hammer can be evaluated according to the specific environment of the operation site.

For example, if the site is carried out in concrete breakage, gas discharge, water pipe excavation and other very complex large-scale activities, you can use 9000w-15000w electric crane, which can make the operation safe, stable and efficient; For the demolition of small furniture, you can use an electric hammer with 300w-1000w power, which is simple to operate, less expensive, and the effect can also reach a more ideal level. Therefore, the 35mm impact drill with a high power electric hammer is suitable, and it can be recommended to use a 1500w-3000w electric hammer, which can not only save time but also ensure the processing quality, and make it more efficient and modernized in the safety travel chain.

Summary. The power of the electric hammer used in the 35mm percussion drill should be determined according to the actual situation, in general, the power of the electric hammer should be related to the size and material of the drill bit, for example, if the drill bit is a metal material, generally choose a rotary hammer with a larger power, such as 1000 watts, and if the drill bit is a brick or other softer material, you can choose a electric hammer with a smaller power, such as 500 watts. In addition, if you are using a larger percussion drill, such as 35mm, the power will also be greater, and you can choose a more powerful rotary hammer, such as 1500 watts.

Hello, I'm E-Info, I'm happy to answer for you, the following is the answer I got for you, I hope it will help you with your questions:

In general, the power of the electric hammer selected should be related to the size and material of the drill bit, for example, if the drill bit is a metal material, generally choose a rotary hammer with a larger power, such as 1000 watts, and if the drill bit is a brick or other softer material, you can choose a smaller power electric hammer, such as 500 watts. In addition, if you are using a larger percussion drill, such as 35mm, the power will also be greater, and you can choose a more powerful rotary hammer, such as 1500 watts.

It should be a hand drill, from the smallest to 13Generally, twist drills are commonly used 6 8 10

Because the impact drill has been eliminated, and now all electric hammer drills are used, and no matter how big the drill body is, the drill shank is the same size.

3 - 4 - 5 - -6 - 7 - 8 - 10 - 11 -12 - 14 -16 (units; mm）

The most commonly used ones in the home are: 6 and 8 mm

1. The most commonly used ones in the home are: 6 and 8mm.

2. Electric impact drill, which is mainly based on rotary cutting, has an impact mechanism that relies on the operator's thrust to produce impact force, and is used as an electric tool for drilling holes in bricks, blocks, lightweight walls and other materials.

3, a kind of drill comprises a tool holder, and the tool holder has a tip, and the tip has two cutting blades that are located on a main plane (c c) and the cutting blade is with a short center cutting cutting edge oriented on the common second plane (e e). The cutting edge forms a point-shaped center cutting cutting edge for entering the workpiece, and thereby the drill bit is centered. On the cutter holder, set up two chip grooves ) described chip groove ) extend from the tip to the bottom end.

In either section along the shank, the chip flutes are positioned radially opposite each other on the pipe plane, and the pipe plane extends at 90° with the common cutting edge plane (f f) of the two cutting strips on both sides of the pipe, and the cutter holder has maximum rigidity in this plane. The orientation of the second plane (e e) of the center cutting edge is approximately 90° to the main rigid direction (f f) of the cutting edge plane or the bottom end of the shank.
