What is a cordless, brushless Impact Wrench?

An impact wrench is a power tool designed to deliver high torque output with slight exertion by the user. It retrieves stored energy in a rotating mass and then gives it suddenly to the output shaft.

A power tool is said to be "brushless" when it does not have brushes; that is to say, it does not have commutators; hence, the position of the magnets and copper windings that drive the armature are conversely switched; instead, it uses a computer-aided control. On the other hand, a power tool is called "Cordless" when it does not derive power from an attached cable wire connected to an alternating current source. Most cordless tools derive their power source from attached batteries.

Features of a cordless, brushless impact wrench

In all, a brushless cordless impact wrench is an impact wrench without commutators and wires; it uses a rechargeable DC battery as its power source. It is well suited for a site with a limited source of power supply, unlike the corded and brushed equivalence of the wrench, which uses wires and commutators for its mechanism.

Benefits of using a cordless, brushless impact wrench

1. Improved Power:

Replacing a corroded pesky bolt in a regular wrench is tasking and time-consuming. An impact wrench enhances more power and torque behind the bolt.

2. Increased Mobility:

The cordless aspect of the tool enhances the flexibility of movement and spores the user's creativity. Simply because there are no cables attached to the device, you can move around and achieve more in a short time because of the presence of high torque.

3. Quicker Access:

Impact wrenches will help reduce time wasting, and you will move to the next job, reducing the stress level in the job.

Types of cordless impact wrench

Please recall that a regular electric impact wrench is connected via cables (wires) to a power source. Still, our primary focus in this discussion is directed to "cordless" impact wrenches, that is, those that employ other power sources other than alternating current. There are two significant types of impact wrench, they include:

Pneumatic impact wrench

Battery-Powered impact wrench.

1.Pneumatic impact wrench:

A pneumatic impact wrench employs stored air as an energy source to power the tool. This wrench primarily uses a paintball gun driven by compressed air or Co2 gas. It is efficient to use.

2. Battery-powered impact wrench:

A battery-powered impact wrench is driven by a direct current from a battery source. The battery power runs out after a long time, but it can be recharged after use or if the user finds out that the efficiency is dwindling.

Note, in choosing a battery replacement for any battery-powered impact wrench, it is best practiced to use the manufacturers' specified battery, but in the event where you want to use another battery, let it be Li-ON.

Uses of Impact Wrench

Impact wrenches are a very crucial tool used in the automotive industry. This tool is mainly used to remove lug nuts when we change the car tires, making it easy for anyone to change in seconds, unlike contemporary times where the manual wrench is used, which takes a lot of time and energy. The impact wrench is a must for all vehicle repair shops and automotive body shops. Other uses of impact wrench include assembly of automobiles, heavy equipment assembly, and maintenance, manufacturing of machine tools, large construction projects, etc.

Impact wrenches have a square-shaped output shaft. They are available in different sizes; the most widely used is the ½-inch square ones.

How to use an Impact Wrench

STEP 1: Safety

Before you start, you'll need safety equipment:

A decent pair of gloves
Clear eye protection
Ear protection

STEP 2: Battery or Air Powered?

An impact wrench has successfully replaced the ratchet and breaker bar, making the removal or tightening of nuts and bolts a speedier process.

They require a lot of power and are often air powered from the air compressor or battery powered like this DongCheng Cordless Brushless Impact Wrench 16 mm 20V 4A DCPB298BM

a popular choice for quick jobs.

STEP 3:The Torque Setting

The impact wrench is a simple power tool with a forward and reverses switch and a trigger, which may be variable speed and, in some cases, a button or dial for multiple levels of torque.

STEP 4:The Impact Sockets

Impact wrenches work with suitable impact sockets designed for the exact purpose. They are usually differentiated from regular sockets because of their flat black appearance and thicker walls.

STEP 5:Torque it up

Don't rely solely on an impact wrench on torque-sensitive fasteners such as the wheel nuts. The torque wrench should always apply the final tension to these jobs.

And be wary of the power offered by an impact wrench as it is more than enough to snap smaller fasteners.

STEP 6: Precautions

Since the impact wrench has a high impact nature, ensure to wear a safety glass to avoid an eye injury. If used in the right situations with a bit of care, an impact wrench saves time and effort on every job.

Maintenance for Keeping Your Impact Wrench Running Smoothly

1. Avoid Using Incorrect Bits or Sockets

When working with an impact wrench, the bits or sockets that should go with it are significant because if the wrong sockets are used, there could be a danger of breakage to the parts of the wrench, thus increasing the chance of injuries and accidents.

2. Ensure to inspect the cord regularly.

Do not drag your Impact wrench along after use; instead, carry the impact wrench by the handle after ensuring it is switched off and check the cords for signs of wear and tear at all times. Never attempt to use an impact wrench with damaged cords; ensure to repair or replace the tool before use.

3. Check the Parts of the Impact Wrench Thoroughly

Whenever you notice any damage on the impact wrench or any part that is not aligned correctly, ensure to get it fixed before further use by a professional service technician to improve and maintain the tool.

4.The Accessories should be cleaned and maintained.

It is best to protect from impact wrench from wet conditions such as excessive heat and sun. Ensure they are cleaned and free of dirt because accumulated dirt can cause misalignment or jamming of the parts, which can also drive the impact wrench.

5. Use only Recommended Grease and Cleaners

Like every tool, the impact wrench should be frequently lubricated using the manufacturer-recommended lubricant only. The valves, impact apparatus, and other parts obey the instructions in your manual. If you have happened to have an oil-filled motor, change the oil following instructions, and with an air-compressed impact wrench, it is crucial to ensure proper airflow with regular testing. Make sure to rule out any damage or leaks to the tool before further use.

6.Avoid Applying Excessive Torque to the impact wrench.

Excessive torque on the impact wrench leads to damage to the sockets and the studs, which are essential for work

and can also result in dangerous accidents. To control this, ensure to cover your impact wrench housing with protective material to protect it from the elements.

7. The Impact Wrench should be cleaned and stored adequately after Every Use.

After each use, ensure to wipe it clean properly, lubricate it with the recommended lubricating oil, and lubrication should be carried out in a well-ventilated area. The best way to do this is by pouring tool oil into the inlet and then turning on the tool for some time, ensuring the lubrication of all the moving parts. Any cleaning or lubrication products on the impact wrench containing detergent should be avoided, and store the tool in a dry, enclosed space.

8. Check the Impact Wrench Regularly

The standard for maintaining the impact wrench is the regular measurement of the torques output. How is this done?

When an impact wrench has turned, it is expected to produce the required working torque, and if failing, it must be repaired by a qualified technician.

List of Most Common Impact Wrench Mistakes to avoid

Whatever type of impact wrench you decide to use, you should use them the right way to prevent damaging the equipment you are assembling. Below are some of the most common mistakes you should avoid.

1) Excessive Tightening of Fittings

One of the main issues with unprofessional users of the impact wrench Is the guarantee that the nut or screw is satisfactorily fixed, and the users may not end up stripping or stretching the wrench threads.

Often the components may be over-tightened and secured beyond the manufacturers' listed specifications, and even if this could work for specific features having a broader room for torque adjustments; for some other parts with not enough room for exceeding the torque, this might do more harm than good to your impact wrench.

The best solution to preventing the over-tightening of fittings on the impact wrench is to use the impact wrench only for the removal or loosening of fittings; also, ensure to use the torque wrench for the tightening of your fasteners.

2) Damaging Threads

Whenever you use your impact wrench to tighten a cross-thread nut or bolt, you will destroy the threads beyond repair. So the best option for avoiding this damage is to thread the bolt manually in the required manner before using it on the impact wrench.

3) The Use of incompatible sockets

It is important to note that ordinary sockets mismatch with impact wrenches. It is safer to use only dedicated impact wrench sockets to ensure no slips and the cyclic loads are tackled appropriately.

4) Buying the Wrong Wrench Size

Purchasing the fasteners and fittings, you will be working with is essential. To achieve this, note the size of the pins and fittings. Also, note that the torque rating of your impact wrench should always be more excellent than the torque that's required by the application.

5)Acquiring the Wrong Wrench Kind

There are various wrenches to choose from; the air impact wrenches and the electric type wrenches. The electric impact turns work best for domestic repair works, while the air impact wrenches have the best power to weight ratio.

Contact Tikweld supplies for the best impact wrench, with the availability of recognized brands such as Dongcheng, Bosch, Ingco, and Maxmech, to name a few.

What you should consider when choosing an Impact Wrench

The following are some main features to look out for when choosing an impact wrench; the parts should depend on the applications you will be carrying out.

Look out for features such as 'high torque.' The higher the torque (measured in newton meters (Nm)), the more twisting force the machine can produce
Brushless motors offer a longer runtime and better performance.
Impact wrenches with a hog ring socket provide more efficient torque delivery.
Models with multiple torque settings allow you to tailor the torque output to the application.

Frequently Asked Questions on Impact Wrenches

1. What's the Difference Between an Impact Driver and an Impact Wrench?

An impact wrench is simply a fastening tool that uses a square drive attached to sockets to tighten and loosen bolts. The impact driver is a screwdriver specialist with a 1/4" hex collet that accepts 1/4" hex shank bits. It is mainly used to drive long bolts and screws. They are much more efficient at driving screws than the usual standard drill drivers. The impact wrench is the best in high torque situations.

2. When should I use an impact wrench?

Impact wrenches are used in applications where a much greater force is required, such as when the nut is difficult to break loose or a hand wrench cant do the job. The most common use for impact wrenches is to change car tyres.

3. How much torque do you need for an impact wrench?

An impact wrench needs about 500 ft-lbs of torque to remove lug nuts. In most cases, you will need the same amount of torque you used to tighten the lug nut to remove it. So, if you over-tightened it, you might need more than 500 ft-lbs torque.

4. How much torque do you need for an impact wrench?

5. Where are impact wrenches used?

Impact wrenches are used in many industries, such as heavy equipment maintenance, automotive repair, major construction projects, product assembly, and any other instance where a high torque output is needed.

6. Is it worth getting an impact wrench?

Yes, it is because an impact wrench is not only for professional use but also for DIY activities in the home, such as car repairs and other bits of work. It can even be an essential tool to get the job done in some cases. So, you must be able to find one that's right for your project.

7. Can an impact wrench be used as a drill?

Impact wrenches are not designed to drill holes, and all the accessories used on a drill driver cant be used on it. if you need to drive a lot of screws – especially screws that are either thick or long – a cordless impact driver will outperform a cordless drill every time.
