There are basically two types of grinders to use: pneumatic grinders and electric grinders. Safety-wise, electric angle grinders are also susceptible to motor burning due to high pressure. Another notable difference between the two types of grinders is the level of specialization displayed by both types, pneumatic angle grinders being a vastly superior option.
You can only make an informed decision once you have a full understanding of your tool’s requirements coupled with knowledge about the different technologies powering the tools – be it pneumatic or electric. Grinders are commonplace in many industries, and electric and pneumatic tools are the most widely used. It’s worth seeking the advice of trusted experts and distributors to double-check that the tool you choose is the most appropriate for your application and will deliver on your expectations.
I recently moved over to air, I just use the portable compressor for most work so the compressor noise isn’t an issue, and the electric bill doesn’t change just because you went from an electric drill motor to an electric compressor motor, you’re still turning the same drill bit, energy in, energy out. The air tools fit all in one roll cab drawer while the cases for the electric tools took up an entire shelf of the same footprint. Electric tools are convenient, you have to consider whether you can just run an air line from the garage into the house if you needed to, or if you don’t mind putting the portable compressor in the truck to do something at a friend’s house.
So I just got a 60 gallon compressor for my home shop and decided to buy all the air tools. I bought a 4 1/2 angle grinder and it feels pretty anemic at the 90psi operating pressure. It grinds ok and doesn’t really hang up but feels like it removes noticeably less metal.

I’m trying to decide between a milwaukee angle grinder or a pnumatic grinder. Air is probably safer – the motor rotor is part of the reason electric angle grinders have a lot of momentum, and it is very important to wait for them to stop before you put them down.
angle grinder air vs electric Related Question:
Are air grinders better than electric?
Superior Ergonomics and Power to Weight Ratio Pneumatic grinders offer a better power to weight ratio than electric grinders. Simply put, pneumatic grinders produce more horsepower in a smaller and lighter package.
Are air tools better than electric?
They usually provide more power and more speed than a cordless tool. The air-powered tool is significantly faster. It also has more hits per revolution than the electric one does. The rpm difference is considerably more noticeable on air ratchets as well.
What is the difference between a die grinder and angle grinder?
In a nutshell, a die grinder is typically smaller and has several different attachments that can help you cut, sand, polish, and various other things. The angle grinder is a larger and often heavier tool that uses a rotating wheel to grind, sand, or cut larger materials.
What is an air grinder used for?
Air angle grinders are a common industrial tool that uses heavy-duty, abrasive cutting discs to cut through steel, concrete and other solid materials.
What is Airdriven grinder?
Air Grinders These air tools are hand-held devices powered by an air compressor. Use them in applications such as grinding, sanding, honing or polishing material (typically metal, but also plastic or wood).
Is a rotary a pneumatic tool?
Once the air enters the tool, it’s fed through a pneumatic motor that converts the compressed air’s energy into mechanical work. Linear-action tools like hammers and nail guns typically employ a piston-style actuator, while rotary-action tools use a geared or turbine-style motor.
What is electric grinder?
An angle grinder is a handheld power tool that can be used for a variety of metal fabrication jobs that include cutting, grinding, deburring, finishing and polishing. The most common types of angle grinder tools are powered by electricity; either corded or battery powered.
How does a pneumatic grinder work?
Once assembled, the way it works is that when you turn on the compressor, the rotor spins and the rotor blades come out and they spin to create a powerful flow of air, much like a propeller in a boat. The power generated rotates the spindle, which then spins whatever grinding disc you attached to the grinder.
Why are air tools cheaper?
When considering cost, find the balance between what you are spending and what you are getting with the type of power tool you choose. Pneumatics have larger upfront costs, lower back end costs. Air tools themselves are usually less expensive than their electric counterparts. They also tend to last longer.
Why do shops use air tools?
The Benefits of Air Tools Compared to electric tools, air tools are usually lighter and smaller, but offer the same amount of power. Air tools can also be easily adjusted to deliver more torque and RPM by adjusting the airflow from the compressor. Doing so can allow you to finish jobs faster and easier.
Why do people use air tools?
Cost: Air tools provide low-cost maintenance and operation because they have fewer moving parts and simple design. Safety: Air tools reduce the danger of electric shock and fire hazard. They also run cooler and cannot be damaged from overloading or stalling.

Is a die grinder worth it?
Die grinders are a great choice, as they’ll be able to get rid of the paint in smaller areas that your sander cannot reach. You can also install a cutting wheel to get into small areas and remove sheet metal that needs replacing.
Can I use my angle grinder as a sander?
An angle grinder can be used as a sander if the disc on the grinder is made specifically for sanding. With the high velocity of speed that comes with using an angle grinder, a sanding disc can do twice the sanding capabilities in a shorter amount of time than a traditional sander.
Can I use a drill as a die grinder?
Drill Attachments for Cutting Metal cut-off kits come with some metal cutting discs and a ¼” rounded mandrel that can fit into a pneumatic air die grinder, In a pinch, you can easily fit the mandrel into your drill and use it as a cutter.
