The Complete Guide to Buying Pneumatic Angle Grinders

A pneumatic angle grinder is a tool that is characterized by operating differently from other grinders. Although the final work obtained may be the same, this type of tool is characterized by operating thanks to air pressure.

It can be directly from the grinder, as it can also be connected by hoses to a diesel compressor. This means that they do not have a built-in motor to work with electricity. Many grinders use electricity directly to operate, these power tools are the most common on the market.

However pneumatic angle grinders are also sought after and turn out to be of good quality. Its energy impulse through a compressor allows you to carry out DIY tasks such as carving, polishing, roughing, cutting, sanding and many more depending on the need and the accessories and tools that can be adapted to it.

With this grinder, you can also work on different surfaces such as curved, smooth, flat, rough or deep. There are several aspects to consider when buying a pneumatic grinder.

Disc Diameter

The diameter of the disc they use, which is proportional to the size of the grinder, a grinder is usually the most general way to distinguish between different grinders.

Angle grinders can be distinguished into two types: Mini grinders are grinders who can place a disc of 115 mm or 125 mm. They are usually around 500-1000W, although there are professional mini grinder models up to 1500W.

They are ideal tools for jobs that need manageability since they are light, very handy, versatile and functional tools. They are used for work on small or difficult to access surfaces, on less hard surfaces, etc.

They are also the most used in DIY since, in DIY tasks, handling is preferred over high power since normally you do not have to carry out very heavy work. At the same time, they are cheaper.

Large angle grinders are those grinders that can place a 230 mm diameter disc on their axis. These tools are widely used in practically all construction sectors. They are powerful, robust and strong grinders, ideal for heavier work on larger or harder surfaces. They are widely used to cut or devastate large surfaces, to polish or strip wide surfaces, etc.

Quality

Among the grinders as in almost all tools, you can find professional tools and DIY tools. The professional angle grinders are tools that are designed to work for long hours and high standards.

On the contrary, DIY angle grinders are tools designed for small occasional jobs and with not very high levels of demand, since if you force the grinder a lot you may end up burning it.

Speed

The pneumatic angle grinders consist of grinder models that have an electronic system for the regulation of revolutions that allows the user to select the speed of rotation of the disc.

This function is a truly useful feature, especially for polishing jobs where precision is required since it allows you to adapt the turning speed to the situation you are in, the material you are treating and the function you want to give to the grinder.

The anti-vibration system is a system that some angle grinders have that reduces vibration during work, and therefore also effort on the user. This increases the precision and comfort of work.

Frequently Asked Questions (FAQs)

1. Why are 9 inch angle grinders banned?

9 inch angle grinders have been banned from many work sites due to the increased risk of injury. Workers often remove guards or use incorrect discs, leading to catastrophic injuries and fatalities.

2. What is a pneumatic angle grinder used for?

Pneumatic angle grinders are best suited for large, heavy-duty industries that require high-power tools. They are commonly used in industries such as railcar manufacturing.

3. Are air grinders better than electric?

Pneumatic (air-powered) grinders are generally considered better than electric grinders. They are lighter, more powerful, and offer better ergonomics. With proper maintenance and lubrication, pneumatic grinders can be used continuously.

4. What is the difference between a pneumatic grinder and an electric grinder?

Pneumatic grinders have a better power-to-weight ratio than electric grinders, making them more ergonomically effective. They also produce less vibrations and noise compared to electric grinders.

5. What are the OSHA requirements for angle grinders?

According to OSHA standards, the grinding face of the wheel or disc of a right-angle grinder should be held at an angle between 5 and 15 degrees from the grinding surface. Accessories not recommended by the manufacturer should not be used.

6. Where should angle grinders not be used?

Angle grinders should not be used in areas where there is grain dust or other combustible dust accumulation. They also generate sparks, so a hot work permit may be required before use.

7. What are the disadvantages of an angle grinder?

Angle grinders can be dangerous power tools. They can cause severe cuts due to kickbacks, and the discs can shatter or disintegrate, potentially causing fatal injuries.

8. What size air compressor do I need to run an air grinder?

The size of the air compressor needed to run an air grinder typically falls in the range of 10 to 110 CFM. Lower CFM compressors are suitable for small tools like grinders and sanders.

9. Are pneumatic grinders any good?

Pneumatic grinders offer a better power-to-weight ratio compared to electric grinders. They provide more horsepower in a smaller and lighter package.

10. What are the 3 common types of grinders?

The three common types of grinders used in the construction industry are angle grinders, surface grinders, and die grinders. Each type serves its own purpose and design, such as creating angles, special surfaces, or fine sanding and polishing.
