What are the precautions for loading and unloading drill bits with percussion drills

1. Before operation, it is necessary to check whether the power supply is consistent with the conventional rated 220V voltage on the power tool, so as not to be misconnected to the 380V power supply.

2. Use a percussion drill.

Please carefully check the insulation protection of the machine body, the auxiliary handle and the adjustment of the depth gauge before the machine is loose.

3. The percussion drill must be loaded with alloy steel within the allowable range of 6-25mm according to the material requirements.

Percussion drill bits or perforation general purpose drill bits. It is strictly forbidden to use drill bits that are out of range.

4. The percussion drill wire should be protected, and it is strictly forbidden to drag the wire all over the ground to prevent it from being broken and cut, and it is not allowed to drag the wire into the oil and water to prevent the oil and water from corroding the wire.

5. Use the power socket of the percussion drill.

Must be equipped with leakage switch device, and check whether the power cord is damaged, during the use of the impact drill leakage, abnormal vibration, high heat or abnormal sound, should immediately stop working, find an electrician to check and repair in time.

6. When replacing the drill bit of the percussion drill, a special wrench and the drill bit should be used to lock the key, and the use of non-special tools to beat the percussion drill should be eliminated.

7. When using the percussion drill, remember not to use too much force or skew operation, be sure to install the appropriate drill bit and adjust the percussion drill depth gauge in advance, and use the force slowly and evenly during vertical and balanced operation, and do not force the use of oversized drill bits.

8. Proficient in mastering and operating the functions of forward and reverse control mechanism, elastic screws and punching and tapping.

1) Use special wrench and drill bit to lock the key;

2) Do not use non-special tools to hit the percussion drill.

3) Tighten the 3 claws with the key, drag them with your hands, click the switch, and see the verticality of the drill bit rotation without going around and then drilling. Unplug the power supply without drilling, and use the key to loosen and pull out the drill bit.

Usually you need to drill a hole in iron or other hard materials, and this is when the percussion drill bit comes in handy, but does anyone know what types of percussion drill bits are and what are they used for? Is there anything to pay attention to during use? Today, I have collected some relevant knowledge to share with you, hoping to bring you some help.

What are the percussion drill bits:

The drill bit material is generally made of high-speed tool steel or cemented carbide, while high-speed steel is often used in the factory, and coolant will be added at different speeds according to the different materials when drilling.

1. The drill bit for drilling metal is high-speed steel, which is a black drill bit, which can be drilled on metal materials such as alloy steel, non-alloy steel, cast iron, etc., and pay attention to the speed not to be too high during operation, so that it is easy to burn out the blade of the drill bit.

2. The masonry drill bit is used for punching holes in concrete materials and stone materials, and the cutter bit is cemented carbide material.

3. Woodworking drill bits are required to drill holes in wooden materials, which do not require high hardness of cutters, and the cutter material is high-speed steel. Its practical drill bit for drilling metal can also drill wood. However, because the wood is easy to heat up, the brittle chips are not easy to come out, so it needs to be rotated slowly when drilling, and it is often necessary to withdraw to remove the brittle chips.

4. If you need to drill holes in ceramic tiles or glass with high hardness, it is recommended to use ceramic tile drill bits, and the tool material is tungsten carbon alloy with high hardness, so pay attention to controlling the speed of the drill when using.

Precautions for the use of percussion drill bits:

1. Drill bits of different materials are used to drill different materials, the harder the cutter, the worse the toughness, and the finer the drill bit, the worse the stiffness. Therefore, it is necessary to control the speed of drilling, and it is best to add appropriate cooling oil or water when drilling. Nowadays, some drills are coated with hard metal films, and they are used to drill steel, iron, and other materials without heat treatment, which are easy to stick to the drill bit, so it is best to clean and lubricate the drill bit with soapy water before drilling.

2. Before using the drill bit, it is best to make a good sample eye on the material to be drilled, so as to prevent the drill bit from deviating at the beginning, causing inconvenience.

3. It is more suitable to drill iron with black drill bits on all drill bits, and it is occasionally used in daily life, so it is recommended to spare one at home.

Summary: The above is for you to introduce the percussion drill bit and the relevant content of the precautions for the use of the percussion drill bit, I believe that after reading the type of percussion drill bit and the later use have a certain understanding, if you still need to know more about the relevant aspects of knowledge, welcome **** Rilong network information, will present more wonderful content to share with you.

1) Use special wrench and drill bit to lock the key;

2) Do not use non-special tools to hit the percussion drill. Qin Yuyu.

3) Sharpen the sail with a key to tighten the 3 claws to be reliable, drag it with your hand and walk around without moving, click the switch, and see the verticality of the drill bit rotation without going around and then drilling. Unplug the power supply without drilling, and use the key to loosen and pull out the drill head.

First of all, the power is off, the hand can not touch the drill bit, you must wear safety gloves, and the electric drill can not be on people. The rest is gone, all these electricians have learned in class.

Just aim at those card slots inside, nothing else.

What do you need to pay attention to when percussion drills?

The percussion drill is a double insulation design, safe and reliable operation, no need to use protective grounding (zero) when using, you can use a single-phase two-pole plug, and you can use it without wearing insulating gloves or insulating shoes. In order to make the operation convenient, flexible and powerful, the impact drill is generally equipped with an auxiliary handle.

Since percussion drills do not have grounding (zeroing) protection, special care should be taken to protect the rubber sheathed cables. When moving the drill by hand, you must hold the handle of the drill, and you cannot drag the rubber cable when moving. The rubber sheathed cable cannot allow the wheels to roll and pedal; Prevent rat bites.

The plastic shell of the impact drill should be properly protected, not cracked, and not in contact with gasoline and other corrosive solvents.

1.The grease of the ball bearings and reduction gears in the impact drill should be kept clean and replaced.

2.Wear goggles when using them. Pay attention to prevent iron filings, sand and other debris from entering the inside of the electric drill.

3.After the impact drill is used, the shell should be cleaned, the rubber cable should be coiled, and placed in a dry and ventilated place for storage.

4.Impact drills should not be used in places where the air contains flammable and explosive components.

5.Always check that the rubber cord is well insulated.

6.Drill ingots should be used to assemble and disassemble the drill bit, and other tools should not be used to beat.

7.Remove the oil, check the spring pressure, replace the worn brushes, and repair them in time when a large spark occurs.

8.Replace the bearing oil regularly.

9.Do not use electric drills or percussion drills with gloves.

In addition, there are two types of percussion drills, electric and pneumatic, and the precautions for the use of electric percussion drills are basically the same as those of hand drills, and the following problems should also be noted.

1.The power of the percussion drill is relatively large, and you must pay attention to the load of the power socket when connecting the power, and you need a large grip when holding the percussion drill.

2.The percussion drill is mainly used for punching holes in the wall in the installation of doors and windows, and when punching holes upwards, it is necessary to pay attention to wearing a protective cover to avoid ash ballast falling into the eyes.

(1) For electric drills that have not been used for a long time, the insulation resistance between the winding and the casing must be measured with a 500V shake meter before use. For the electric drill in use, the insulation resistance should also be measured regularly, and when the insulation resistance is lower, it should be dried until the insulation resistance is higher.

2) Check whether the power supply voltage is consistent with the rated voltage of the electric drill.

3) Check whether the protection zero connection of the electric drill is good.

4) When moving the electric drill, do not drag the rubber soft wire, so as not to break the wire or cut the insulation and cause the risk of electric shock. When using, the electric drill should not be damaged by impact and damage to the shell and other parts.

5) The force should not be too large when drilling, so as not to cause overload and burn the winding of the electric drill. Especially when the borehole is about to be drilled through, the pushing force should be appropriately reduced.

6) When using, it should be noted that the temperature rise should not be too high.

From the perspective of internal factors, the quality of the drill bit is not good enough, and from the perspective of external factors, the situation at the bottom of the well is complicated. There are too many reasons for that. The drill bit falls off during the electric hammer beating, one is that the drill bit is not stuck well, or the drill bit card groove is damaged, and the other is that the electric hammer card head has a problem, and the card head does not pop out.

How deep should the expansion screw be hit? The old electrician drilled like this, the depth was just right and there was no dust.

Xiaolian percussion drills rely on rotation and impact to work. Percussion drills rely on rotation and percussion to work. A single impact is very slight, but a frequency of more than 40,000 shocks per minute creates a continuous force.

It can be used for natural stone trapping or cracked concrete. When the percussion drill is working, there is an adjustment knob at the drill 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 each other to achieve the impact effect, but the impact force is far less than that of the electric hammer.

It is not suitable for drilling reinforced concrete soil. Uncle Cake.
