Features to Consider in an Angle Grinder

An angle grinder isn’t something you should buy randomly. Whether you want it for your DIY projects at home or for professional projects, this little tool can either slow you down signifitangly or speed up your work quite a bit.

Shopping for the right angle grinder isn’t easy because of the plethora of choices available on the market. With this guide, you’ll be able to find out which angle grinder is perfect for you.

Motor

This is the feature you need to look for first, because it’s the motor that’ll determine the speed and power of the angle grinder.

Based on the model and the manufacturer, you’ll be provided with a rating for either amps, horsepower, or both. Get a grinder with at least a 6 amp motor for sufficient power.

The motor amp will indicate how hard the angle grinder’s motor works when you’re using it. A high amp rating also means that less heat will emit from the motor when you’re working with it. A higher amp motor will also be more durable as cooler running motors last longer compared to ones that are almost always running hot side.

On our list, there are some great models that hover in the 6-8 amp range, while the DeWalt packs a ton of power in its 11amp angle grinder.

RPMs

The revolutions per minute (RPM) indicates the number of times the wheel of an angle grinder spins in one minute.

RPM is very important for cutting and grinding wood, metal, and others. Your angle grinder will grind and cut faster with a higher RPM.

Most available models come with 10,000-11,000 RPMs.

Wheel Size

There’s no industry standard when it comes to the wheel size of angle grinders. However, it does help when you get a wheel size that’s easily found so that it won’t be a problem whenever you need to get a replacement.

4 ½” is the most commonly available wheel size. You’ll find angle grinder wheel sizes ranging anywhere between 3 ½” – 9”.

Larger wheel sizes aren’t as popular because the smaller wheels can easily turn at a faster RPM, and can get into narrow spaces.

Save the bigger wheels for heavy duty grinding and cutting projects. Big wheel angle grinders are better left for cutting through thick materials.

Ease of Handling

Ease of handling should always be a priority, especially when it comes to work tools like angle grinders. Look out for these features to make sure your angle grinder is more convenient to use.

Ergonomic Design

The handles or anything to hold on to should fit naturally in your hands. This’ll save you a lot of fatigue while working with this handy tool.

Barrel Thickness

Examine the size of the barrel/body as you’ll be holding on to this while working. Typically, the thinner the width of the body/barrel, the easier it’ll be for you to hold on to.

Handle Grips

Multi-positional handle grips can make a world of difference when you’re working with an angle grinder for long hours. With an adjustable handle grip, you’ll be able to customize the tool to your personal preference.

Side Handle

All angle grinders come with a side handle, and that’s a great plus. That said, not all side handles do what they’re supposed to do – make you as feel comfortable as possible while working with this tool. For a very good grip, look for a textured and slim handle.

A lot of models also provide the option to change the tilt of the handle’s position to increase the comfort level for you. There are also certain models that provide an extra handle which you can attach on either side of the tool to customize it according to your dominant hand.

Weight

If you’re planning to work with this angle grinder for long hours, you might want to consider its weight. A bulky tool will tire you easily and slow down your pace. On the other hand, if your angle grinder is too light, it’ll not withstand heavy duty use for an extended period of time.

At a minimum, opt for a grinder that weighs at least 3 pounds. Anything less than that we would question its durability.

Any grinder over 10 pounds is going to get real heavy in your hands quickly. Shoot for something lighter than that if you can.

Safety

Many power tool manufacturers put a lot of attention to safety features. Your angle grinder should at least provide a long lasting guard. Look for added safety features like power switch lock to make sure it doesn’t start up accidentally when you leave it unattended.

Materials

Always examine what materials were used to make the gears and housing of the angle grinder. Ideally, you want its components to be made from metal. If you’re not planning to use your angle grinder too frequently or if you’re using it for small projects, nylon or plastic gears will do just fine.

Dust Protection

The biggest enemy to all power tools, electronic devices, and appliances is dust. Any angle grinder with dust protection features will be more durable than its counterparts. Many angle grinders these days seal their motor and other gears to protect it from the destructive effects of dust and dirt.

You’ll also find some models that are built with specially designed technology to expel dirt so that it doesn’t accumulate inside the tool components and cause damage over time.

Durability

A lot of features can contribute to the durability of an angle grinder so that it holds up better and has a longer life span. One such feature is the material of the construction it’s made from.

The best material for body construction is lightweight polymer plastics. They’re virtually unbreakable and resistant to chemicals and heat under normal working conditions.

Another feature to keep an eye out for is the vents. Make sure it’s constructed in such a way that it doesn’t allow dust particles or chips to enter the motor compartment easily.

Features like these really contribute to the longevity of your angle grinder.

Warranty

Warranties are generally an added bonus but especially necessary in power tools like this. Angle grinders are typically not very expensive, but they aren’t disposable products either. Give yourself some peace of mind and opt for a model that comes with as long a warranty as possible.
