Our pick, DeWalt’s 4 1/2-inch Angle Grinder offers the high-end and features that one would expect from this trusted brand. It’s also very cost-effective, too.

The factors to consider when choosing angle grinders

Power and size

The size of discs determines the size of angles grinders (or wheel) they are able to accept. Two three-inch models are readily available but 4 and a half inches are most likely to be the most used.

The most powerful tools are between seven and nine inches. Although some tools are small, others can be large and heavy. It’s worth looking at the general dimensions and weight, particularly if you’re likely to use it for long durations.

Like the majority of power tools, there is the option of using corded or unplugged -however, the majority are corded. Tools that are corded are rated according to amps. 5 or 6 amps are the norms for the mid-range angle grinder, however, some models can go as high as 11 amps.

The larger models can go up to 14 amps which is a sensible limit as conventional electrical outlets provide a maximum of 15 amps. Certain angle grinders that are heavy-duty employ horsepower instead.

Cordless models can be found available in 20 and 18-volt versions (which in actual terms means the exact same thing). The most important thing to consider can be found in the amp hours (Ah) that the batteries can provide.

Although the numbers don’t directly reflect the running time, a battery that has 4Ah can last at more than twice the time as a 2Ah model. Angle grinders that are cordless are extremely power-hungry equipment, therefore you should get the most Ah you can get.

We don’t suggest less than 4 Ah. As high as 9Ah models are offered for certain brands, however, they are costly.


Gear Material Used

For angle grinders that aren’t as good, it’s possible to have drive gears constructed from nylon or similar plastics We would advise against purchasing these. Metal gears are far more robust.


They offer a protective shield to keep dust, debris, and sparks, particularly when grinding metal. Guards typically offer a few adjustments. The amount of adjustment and accessibility vary.

Side handle

A side handle is typically provided, which provides more control than simply holding the body. You can move the most left-hand to right-hand, and some models have three different positions. They can be eliminated completely when they obstruct the working.

Spindle lock

Spindle locks are convenient that allow you to use only one spanner to switch the disc. A few angle grinders that are cheap usually have one, which means they require two spanners.


It’s great to have case to keep discs, grinders, and spanners in one place, but most of the time you only get the cardboard case that it was packaged in.

Disks can be given. It’s crucial to verify whether they’re stone- or metal-cutting prior to use (composition differs and is marked by the disk). Disks that look like small chainsaws can cut wood. Buffers and pads offer an alternative for polishing although a separate machine is generally employed in professional shops.


There are a variety of cheap angle grinders made by no-name brands for less than $20, but good quality begins at about $30. Between $50 and $100, you can have an array of high-quality models.

The only reason to pay more is for cordless models, which could be priced at $150, or for industrial models with heavy-duty capabilities which could cost around $300.


Q. What safety equipment should I use when working with an angle grinder?

A. Standard safety clothing is suggested such as dust masks, gloves, and goggles, or a face shield. Ear protectors are an excellent idea because angle grinders can be extremely loud.

Q. Do angle grinders require much maintenance?

A. Surprisingly rare. If you’re cutting rocks, cement, or other materials. Make sure to clean the remaining powder after you’re done (or use a blow-gun when you have one). The models with cords may need the brushes of the motor to be changed frequently but it’s an essential procedure.
