Angle Grinders Buying Guide

Best Angle Grinders

Don’t purchase your angle grinder before you check out our detailed buying guide below.

What Do You Use an Angle Grinder For?

There are many reasons why one of the best angle grinders could be your new favorite tool, but let’s take a quick look at some of the frequent uses for these units. First, angle grinders do an excellent job of sharpening dull blades.

Angle grinders are perfect to sharpen everything from shears to axes to mower blades. They also do a good job of scraping surfaces, like mortar. While you could use a mortar and chisel for that type of task, the best angle grinder will get the job done better and far faster.

Are you tired of your garden tools gathering dirt and grime, with no apparent way for you to get the debris off? With a trusty angle grinder and the wire wheel component, you can scrape off elements like chipped paint and rust with total ease to make your tools like new again.

You can even use an angle grinder for a task like retiling your floor.

Different Types of Angle Grinders

Not all angle grinders are ideal for mass use, and some of the products and the market are strictly best for the professionals.

There are three primary types of angle grinders—gas, electric, and compressed. Gas-powered grinders are ideal for professionals in the construction industry who knows how to use them and the types of materials they work with. These gas-powered angle grinders are immense tools that are strong enough to slice through blocks, bricks, steel, and other very thick materials.

Electric angle grinders are the common choice for many because all you need is a battery, wall outlet, or transformer to charge it up. Both pros and homeowners alike use electric angle grinders, because they are efficient for light to moderate-intensity projects.

If you are brand new to angle grinders and aren’t sure which choice is right for you, the best angle grinders with electric power will be your best and safest bet.

Finally, compressed angle grinders are air-powered, and are the type you will frequently see in an auto shop. Compressed grinders leverage air that powers up the tool. However, air-powered angle grinders are typically the most expensive option on the market and only professionals usually use them.

If you are an angle grinder novice and still learning the ins and outs of how these units work, an air-powered grinder probably won’t be the ideal choice for you at this point.

Features to Look For

These are the key features you’ll want to pay attention to when choosing from the best angle grinders.

The Angle Grinder Disc Size

One key component to keep in mind when looking at various angle grinders is the disc size it features. In most cases, the larger a disc is, the more powerful the device motor will be. Discs come in a wide range of designs and sizes, but the most common variety is the 115 mm and 230mm varieties.

If you prefer to select an angle grinder with a more compact disc, you may have to find a pneumatic device instead.

Consider the Unit’s Motor Power

Different angle grinder products feature varying degrees of motor power, including voltage, amp ratings, and wattage amounts. The best angle grinders typically sport wattage in the 500 to 2500 range, with a 4 to 15 amp capacity.

If you only intend to use your angle grinder for simple household projects, you probably won’t have to worry so much about finding a product with a high-speed motor and extensive output.

Dust Retention

The best angle grinder product should include a component that wards off dust and debris, both to enhance its overall performance and to keep the motor functioning properly. The best angle grinders on the market should include dust management systems, such as a diamond blade.

Even if you have to pay a bit more for a dust management component, you will save yourself the considerable time and expense you might encounter otherwise if your motor clogs with debris a few months down the line.

Is It Comfortable to Use?

Your comfort level is another aspect to take into account when shopping for the best angle grinders. If the unit isn’t comfortable for you to use, chances are you’ll try to avoid using it, which renders your purchase essentially a waste.

There are a few different features that affect comfort when it comes to the best angle grinders. For one, smaller units are much simpler to use, particularly if you plan to use your angle grinder for a prolonged period. Second, units featuring anti-vibration blades are an added bonus, because all that vibration can wear your hands and wrists out pretty quickly.

If you really need a massive angle grinder for commercial jobs though, just keep an eye out for comfortable grip components that help reduce hand and wrist fatigue.

Safety Components

The best angle grinders always feature safety components to protect the operator. For example, the unit might include a wheel guard that you can adjust as needed, or a slip clutch so you don’t have to worry about accidentally turning the device on.

Speed

Finally, look out for the best angle grinders’ speed rating when determining which choice is the best one for you. The best angle grinder products usually feature speed ratings ranging from 5,000 to 10,00 rpms.

Products with speed ratings on the higher end of the spectrum are best for professional use, as they increase injury risk if you don’t wield them properly.
