Analysis of the Advantages and Disadvantages of Electric Tools and Pneumatic Tools!

When it comes to maintenance tools, many people strongly recommend electric tools. They come in many varieties, are easy to use, and have low prices, so are especially suitable for home use. There is another powerful and efficient category of tools that are widely used in the tool industry that operate by air pressure; pneumatic tools. So, what is the difference between the two, and how should one choose? Let’s compare.

Power hand tools can be divided into electric hand tools (such as electric drills, electric screwdrivers, chainsaws, etc.) and pneumatic hand tools (such as pneumatic screwdrivers, pneumatic wrenches, pneumatic sanders, etc.) according to the external power source used. What is the difference between electric tools and pneumatic tools?

The initial investment for electric tools is low, but for long-term use, the energy consumption is high, and the cost of tool maintenance and replacement is also high. One advantage of pneumatic tools is that they can be used in harsh environments, however they require regular maintenance.

Pneumatic refers to the use of high-pressure gas to drive the mechanical device to rotate and tool. Electric tools convert electrical energy into mechanical energy to drive the tool. Pneumatic tools are safer than electric tools, but are bulkier in size. Electric tools are more compact in size.

Precautions of Use

Pneumatic tools:

  1. The air is easy to obtain and the working pressure is usually quite low. Used air can be easily discharged on the spot without the need for recycling pipes.
  2. Air has low viscosity and small flow resistance loss so is convenient to use with a centralized air supply and tubing.
  3. Pneumatic actuators move at a high speed.
  4. Pneumatic tools are highly adaptable to most environments. They are reliable in humid and dusty environments, and over wide temperature ranges. They do not pollute the environment, and have no fire or explosion hazards, so are very safe to use.
  5. Simple structure, convenient maintenance and low cost.
  6. Pneumatic components have long service life.
  7. Pneumatic tools and their components are smaller than those of the hydraulic tools so can operate at higher speeds.

Electrical tools:

  1. Carefully check the appearance and for any damage. The switch should be flexible and operate without jamming. The power cord and casing of the electrical tool should be intact.
  2. Hand-held power tools with metal shells should have a reliable protective grounding wire. The power lead is a multi-core, soft rubber sheathed cable, and both ends of the grounding protection wire should be firmly connected.
  3. Hand-held power tools should be used by professional personnel with certain professional knowledge. The relevant safety operation rules should be strictly observed during use.
  4. Before use, check whether the relevant electrical protection devices and mechanical protection devices are in good condition and operating normally. Pay attention to whether the rotating parts are flexible and free from jamming.
  5. When using Class I hand-held electrical tools, the user must wear protective equipment that meets regulations. Proper safety protections should be taken to prevent electric shock such as installing a leakage protector in the power circuit, or wearing insulating gloves, insulating shoes or standing on an insulating pad. When using Class II hand-held power tools in humid and narrow places, a leakage switch should be installed. The working current of the electric switch should be less than 1.5mA, and the action time should be less than or equal to 0.1 seconds. The leakage switch should be inspected by a qualified person regularly.
  6. Occupational hazards of using hand-held electrical tools.

Environmental Adoptability

Pneumatic tools:

While they can be used in harsh environments, maintenance such as dust removal, water removal, lubricating, etc. must be done properly. Pneumatic tools often use air from and air pump powered by an internal combustion engine, so are very portable and suitable for field work. Pneumatic tools can work continuously for long periods of time without overheating so are suitable for large-scale production lines.

Electrical tools:

Electric tools should not be used in wet environments where there is a danger of electrocution. As they can generate electric sparks, they should not be used in places where there are flammable materials that could cause a fire or explosion. They are not suitable for use in coal mines, oil fields and other areas with petroleum present.

Economic Prospect

Pneumatic tools:

The initial investment requires the establishment of air pressure pipeline equipment, but the long-term use is low in energy consumption and tool maintenance.

Electrical tools:

The initial investment is low, but the energy consumption for long-term use is high, and the cost of tool maintenance and replacement is also high. The weight is generally 3 to 4 times that of pneumatic tools, so they are not suitable for long-term work, while pneumatic tools can improve work efficiency.

Essential Cordless Tools for Mechanics

You may find many different power tools in every automobile repair shop, but do you know all about them? Probably not. Corded power tools are becoming less and less popular among artisans with the upcoming technologies in cordless tools for mechanics. For this reason, even in a car repair shop, you will find more cordless tools rather than corded power tools. This article will review the essential cordless power tools you may need in your fully-equipped garage for regular car repairs. Let’s take a look at them.

Cordless Power Tools for Mechanics

Mechanics’ cordless tools are used in different fields ranging from diagnosing problems, conducting repairs, and performing routine maintenance for automobiles, motorcycles, industrial machinery, aircraft, and more. So, the most important cordless power tools for mechanics can vary based on the specific tasks and needs of the mechanic, but here is a list of commonly essential ones:

Cordless Impact Wrench

There is probably no repair shop where you cannot find an impact wrench. For any high-torque situations, you will need a proper impact wrench and a set of sockets. However, the most useful feature is loosening lug nuts from vehicles and machinery like cars and trucks. Some people may mistake this power tool for an impact driver. To know how to distinguish them, you need the following facts:

  •   A conventional impact wrench can accommodate a 1/2-inch socket of various sizes that can fit a wheel lug.
  •  An impact driver has a 1/4-inch hex opening.

Before the popularity of cordless tools, pneumatic-powered impact wrenches were the most commonly used tools in professional garages. But as battery technology improved, cordless impact wrenches got better, brought prices down, and made themselves a viable alternative to the pneumatic types. The most popular feature of these cordless mechanics’ power tools is portability. You should have the ability to freely move around the vehicle and loosen the lug nuts as fast as possible, without the cables all around you.

Cordless Angle Grinder

As you may know, an angle grinder has different essential parts:

  • A spinning wheel that is for cutting, grinding, and polishing
  • A safeguard
  • A housing

 You may not see one in a garage or repair shop all the time, but there are many situations in which you will need one for sure. Removing rust or old paint might be the most used of a grinder.

You can use different sizes of wheels for this action to have the most accurate results. Since the angle grinder is made for cutting metal, the other purpose of a grinder is cutting out metal sheets, such as different parts of a car. On the other hand, having a portable angle grinder gives you the ability to have more control during the process.

Cordless Rotary Tool

Among all the cordless mechanic tools, rotary tools might seem too delicate for a large vehicle. However, they are super handy and efficient for many different tasks.

  • Removing battery corrosion instead of a toothbrush or cutting a rusted clamp
  • Buffing scratches off your car, truck, RV, or motorcycle
  • Cleaning the dirt and smoothing out the scratch with a rubbing compound using the felt wheel in a circular motion

After the compound is dried, remove it with a soft microfiber cloth, and then apply the polishing compound. All these steps must be done in a circular motion, and you can achieve a very first look back on your car using only a rotary tool and some extra wheels. Furthermore, when this tool becomes cordless, you will have more control and you can work in different positions without the wire coming in the middle.

Cordless Polisher/Buffer

Before we get to the advantages of these mechanics’ cordless tools, we will briefly define the difference between a polisher and a buffer:

  •  A polisher is used for more aggressive applications, involved with more friction, and also using abrasive to even out the paint.
  • A buffer is used to modify and improve the clear coat during a less harsh process, which brings out luster and a smoother finish.

It may happen by a carwash when they scrub off dirt with something abrasive, either a Scotch-Brite pad or a brillo pad, which leaves marking marks on your car paint. In this situation, you need a proper polisher to start with. The chosen polisher can be either rotary or dual-action, which could be described in another article.

You simply add some swirl remover to the pad for a light scratch, spray some polishing pad conditioner start to spread the polish around the scratch, and finally polish side-to-side the scratch. In the end, you will have a pleasant and lustrous finish that is incomparable with the original look.

In the whole process, a cordless polisher can have the same power but with more possibilities. You wouldn’t need to look for power outlets to start and no worries about the cable being in the way.

Cordless Heat Gun

Have you ever heard of wrapping a car? No, it is not for preparing a gift, but to have a new look for your vehicle and protect its paint. Car wrapping is another way to change the look of your car without spraying color all over again. This method can also be an alternative for complicated and more expensive painting. You only need a prepared and clean car, a vinyl film, a sharp blade, a squeegee, and a proper heat gun.

Among all the essential cordless tools for mechanics, you will need a powerful heat gun to apply a layer of plastic vinyl coating to heat it and make it stick over the top of the vehicle’s paintwork. There is an undeniable fact that corded heat guns are often used in vehicle wrapping centers rather than cordless ones. Because vehicle wrapping is a long process, and a cordless battery may not last until the end. But for confined and small spaces, a cordless heat gun is a must. Additionally, they are lighter and easier to carry around, so you will be able to work for hours without fatigue.
