Buying the best angle grinder

The main problem people face is in choosing an angle grinder. There are hundreds of them in the market so you must not end up paying more for an overpowered grinder or by buying an underpowered one. 

So how do you make the right choice?

Below are some key things you should watch out for when buying the best angle grinder for yourself. 

This will help you make the correct decision.


Angle Grinder Motor

The motor is the most important component of an angle grinder. It is which drives the disk of the best angle grinder. 

Two things to consider is the size and power output of the motor.

The more powerful it is, the denser material you can work with. Usually, the power rating of an angle grinder varies from 400-2700 W while the amp ranges from 4-15.

If you are buying the best angle grinder only household work then you should consider an angle grinder with lower specs. 

There are some best angle grinders with AC/DC motors. They are quite useful if you want to power an angle grinder with DC power too.


The speed of an angle grinder is directly influenced by the motor. Larger the motor greater is the speed. 

So why does speed matter? 

Higher speed means you can work easily with harder materials. It is also useful if you sharpen things using the grinder. The speed is measured in RPM that is rotations per minute.

Disk Size

Disk Size

Best Angle grinders with smaller motor come with small disk while larger ones have larger disks. Both the sizes have their own merits and drawbacks. 

While larger one will help get the job done quicker the smaller one is used mainly where detailing is required. So if you need to do some precise work like sculpting, then you should use a smaller disk.


Angle Grinder Comfort

If you use an angle grinder quite often and also for long durations then comfort is super important. You don’t want your hands to ache in the middle of work. It is should not be a tiresome experience. 

There are many key elements that make the best angle grinder comfortable. The handle must be the most important element. Many angle grinders come with more than one handle. This helps you to choose the best one according to the type of work and your comfort.

The grip of the handle is also key in deciding the efficiency of the angle grinder. Nobody wants to injure himself just because the angle grinder slipped over his hand.

Other Factors

There are many other features in angle grinder that you should look out for a while purchasing one. 

Like some grinders have variable speed while others don’t. There are many accessories that come with best angle grinder can be important for you. 

Ultimately you want to buy the best package. Brand and warranty are also super important. I would not recommend anyone to buy a non-brandable angle grinder just to save few bucks. 

Some reputable brands that you can trust are – DeWalt Matika Hitachi Porter Cable Bosch You should also keep an eye on the warranty.

Most brands give a three-year warranty which makes the purchase smart. I have listed below some of the best angle grinders I came across while preparing this article.

They are also used to cut or polish. It all depends on the disc that is attached to the spindle. A cutting disc is made up of a very aggressive material. The exact type of material is dependent on what it is intended to cut. There are discs for cutting concrete or steel. The grinding wheel disc is made up of less aggressive material that is intended only to take away little abrasions. The polishing discs are for buffing only. The amount of surface material they take away is so insignificant; it cannot be measured.

Handheld power tools differ in how they are powered. Most are powered by electrical means. This can be done with power cords that need to be plugged in to operate or battery units that need to be recharged. These are used on some construction sites because of their portability. In metal shops, most power tools make use of compressed air as a power source. These pneumatic grinders are available in smaller sizes than their electric cousins because they still are powerful at a reduced size.

The largest and most powerful grinding power tools have an internal combustion engine as a power source. These take two hands to operate and can be seen in emergency situations where a person is being cut out of a car after a wreck. Other common applications are when they are used to cut the asphalt or concrete streets by construction workers.
