Buyer’s Guide on Pneumatic Angle Grinders
A pneumatic right-angle grinder that works efficiently doesn’t have to be the most powerful or expensive. Its characteristics must meet the specifics of the work to be performed. The tool must have optimum power, disc size, speed, etc.
And, of course, the grinder should meet all the criteria in terms of safety. In the following paragraphs, consider what parameters to pay attention to when choosing a pneumatic tool for work.
Power
The power of a pneumatic angle grinder consists of several indicators. The motor power can be between 500 and 700 watts for small short jobs, 900 to 1,200 watts for working with metal, and 1,200 to 2,700 watts for construction work.
The next parameter is the rotational speed of the blade. The smaller the diameter of the disc, the more speed it can develop. For example, angle grinders with a disc diameter of 4-inches can reach speeds up to 13,000 RPM. The devices with a disc diameter of 9-inches have a maximum speed of 6,600 RPM.
Air Speed. The larger the diameter, the higher the speed should be. For minimal work, 150–200 l/min is sufficient; for metal work, 200-250 l/min; for continuous work, 300–500 l/min.
Size and weight
The size of the angle grinder depends on the diameter of the disc you plan to use. For most jobs, cutting non-thick metal requires a disc diameter of 4 or 5 inches. For complex work on thick material, choose large discs ranging in size from 7 to 9 inches. Such grinders already belong to the class of industrial. They have a corresponding cost and weight.
In terms of weight, the devices can weigh from 2 to 13 pounds. The more powerful the sander, the heavier it will be. Typically, a pneumatic angle machine weighs much less than its non-pneumatic counterpart.
Control
The starting method is the difference between a pneumatic angle grinder with compressed air and a conventional angle grinder. An air compressor with hoses and fittings is needed to power a pneumatic tool. Since the pneumatic grinder is powered by air rather than electricity, its capabilities are virtually limitless.
Pneumatics can be used for quite a long time without worrying that it will overheat. It also allows you to work in explosive areas and even underwater.
The pneumatic angle grinder has the following principle of operation. You press the special button, so the air starts flowing into the air motor through the hose. Then the rotor, spindle, and disc start rotating.
Blade
That is the essential part that allows you to perform certain operations. For each tool, there is a specific size of the wheel. Never use a wheel that is larger or smaller than the specified diameter.
The diameter of the disc for an angle grinder pneumatic can range from 4 to 9-inches. The more powerful the tool, the larger the disk it can work with. For domestic needs, a 4- or 5-inch diameter disk is used. The grinders with a 7-inch and 9-inch disc belong to the professional range and are used for repair and construction work.
Since an angle grinder can cut metal and stone and grind different surfaces, the disc material can also be various. There are the following types of angle grinder discs:
- Aluminum oxide discs are suitable for metalwork.
- Diamond-coated discs ― for granite, concrete, and brick.
- Silicon carbide discs ― for concrete, granite, red brick, and natural or artificial stone.
Safety
Protecting yourself from sparks or small metal particles on your hands and face is essential when working with a grinder. Angle grinders have a unique protective cover to do this. It is often adjustable, so it can be set the right way depending on which way the sparks blow.
For safe use, the angle grinder has protection against spontaneous start. Manufacturers equip angle grinders with a soft-start system to avoid significant injury risks.
In addition to being equipped with the proper features for your safety, you must also handle the sander responsibly. Be sure to wear safety glasses, gloves, and closed shoes. Clothing must cover your body fully and not be too loose.
Replace parts carefully. Use only tools designed for the angle grinder. Only try to use discs that match the size of your machine.
FAQ About Pneumatic Angle Grinders
In this section, you will find additional information to help you use pneumatic angle polishers.
How to replace ball bearings in a pneumatic angle grinder?
You must remove the wheel and flanges first. Then remove the wheel guard and handle. Separate the gear assembly from the grinder and separate the spindle assembly from the gear assembly. Once you get to the bearing, remove the old grease and the bearing itself. Then install the new bearing and grease.
How do I put a cutting wheel on my pneumatic angle grinder?
To change the angle grinder’s wheel, you must put a wrench on the nut that holds it. Press the wheel lock button and unscrew the nut counterclockwise. When the nut is loose enough, remove it with the wheel. Put on the new spin and do the same with the nut clockwise.
What kind of air compressor is needed for an angle grinder pneumatic?
Pneumatic angle grinders typically require 60 to 70 pounds per minute, with a 100% duty cycle of 90 pounds per square inch. But this figure depends on the size of the device. To determine which compressor is needed, you should know how much air the grinder needs.
