How Do I Choose The Best Angle Grinder [Buying Guide]

 

 

There are some issues that you need to consider when choosing the best angle grinder. Let’s know them.

Corded or Cordless

In terms of portability, cordless grinders are preferable to corded angle grinders. They are perfect light projects. But a cordless grinder is heavier than a corded grinder as the cordless grinder is powered by an included battery and for its additional weight, this kind of grinder can’t manage high output. If you need higher power output, you are recommended to get a corded angle grinder.

 

RPM

Revolutions Per Minute (RPM) is an important fact while choosing the best angle grinder. Higher RPMs generate greater speed. It is imperative to check on the maximum RPM of the wheel before inserting it in a grinder. The wheel might be damaged if you use a wheel with lower RPM than the grinder.

 

Variable or Fixed Speed

Fixed speed angle grinders don’t allow to change the speed limit. But variable speed angle grinders allow controlling the RPMs for ease and comfortable work. This kind of grinder is preferable to polish sensitive metals or surfaces.

 

Power/Amperage

Amperage denotes the power of the motor. High power or amperage angle grinders can deliver higher RPMs for heavier projects like thick-pipe welding.

 

Disc type

There are different kinds of discs including cutting discs, flap discs, grinding discs, and wire discs. Cutting discs are the thinnest of all discs and they are good for cutting metals. Grinding discs are usually 5mm or thicker and are used for clearing or smoothening rough surfaces.

 

Flap discs are coated with sandpaper and are used for creating smoother surfaces. Wire discs are used for polishing metals or removing paints. You need to choose the right type of disc depending on the work you’re going to do.

 

Disc Size

There are 4 sizes of the disc- 4.5-, 5-, 7- and 9-inch. Perfect disc size depends on the purpose of the work you’re going to do. If you want to do DIY projects, 4.5-inch discs are appropriate as they can easily fit into different places, lightweight, and easy to use. On the other hand, the larger discs are usually used in industrial angle grinders depending on the type of surfaces.

 

Ease of Changing the Disc

The way to change the disc is very important. You should select the grinder which has a Quick-Change-Wheel-Release feature that allows you to change the wheel easily without using a tool.

 

Safety

The best angle grinder offers some safety features for the users including anti-kickback, vibration control, overload capacity, auto brush-off, and so on.

 

Type of Switch

There are two types of switch-Paddle switches and Slide up switches. Slide-up switches are easier to use.

 

Size

The best size of the angle grinder depends on the work. For DIY or small projects, angle grinders with smaller dimensions are appropriate but for industrial projects, you need to have the larger tools.
