Best Angle Grinder Buying Guide

Since thousands of brands make angle grinders, getting the best can be difficult, especially when a beginner. To make the best decision, you need to check out some features.

Motor Power

When it comes to the output power rating of a motor, the best ranges between 500 and 2500 watts. Moreover, the amperage should be within the range of 4 to 15 amps, although it depends on the model.

The angle grinders on our list have different motors with different power ratings. Angle grinders with smaller ratings are suitable for light projects, and those with a higher rating are suitable for use on massive projects like workshops and construction sites.

Safety Features

Handheld power tools come with several safety features which help prevent operator injury. This is a significant factor to check for when buying these tools. When finding the best angle grinder, go for models with an anti-kickback clutch, restart safeguard, wheel guard, lock button, etc. The power tools on our list come with these safety features and safety tips to protect you from any injury as you operate the grinder.

Disc Size

Angle grinder disc size is another significant feature to check out when purchasing an angle grinder. More minor angle grinders models usually require a 4.5″ disc and sometimes a 5″ disc though rare. Moreover, large angle grinders are compatible with up to a 9-inch angle grinder.

DIY lovers favour small-angle grinders since they are lightweight and can be used in tight spaces. Moreover, they’re powerful enough to handle most projects, including sanding, grinding, and sharpening. A large angle grinder is more useful for cutting through steel, concrete, and other hard materials.

Power Source

There are two power sources available for your garage or workshop equipment. When selecting an angle grinder, you can get either cordless models or the best corded angle grinder option. Cordless options get their power from a rechargeable battery, and the best corded angle grinders operate directly from electricity. In most cases, when buying a cordless grinder, you will have to buy a battery since they aren’t packed with it.

Speed

This is another significant feature to check out when buying an angle grinder. How quickly the disc spins is measured in rotations per minute RPM. Pneumatic angle grinders with higher RPM mean they can cut via the target material quickly and easily.

A small angle grinder works at higher speeds, unlike a large angle grinder. Their operation speed ranges from 5,000 to 11,000 rpm. Furthermore, a small angle grinder will have speed controls to vary depending on the project needs. Big and corded angle grinders’ maximum speeds are lower and usually range between 5,000 to 8,000 rpm.

Dust Protection

With time dust will collect at internal parts of the angle grinder. This can lead to vents clogging, overheating and burning the motor. In addition, dust buildup also leads to quicker wear. Thus getting a grinder with a dust ejection system feature is essential, especially when you use the grinder for lengthy periods.

Comfort

Another great feature is how comfortable the angle grinder is. A good grinder should have a comfortable handgrip, be easy to use, and be lightweight. With a comfortable angle grinder, you can comfortably work for longer hours.

FAQs

Are angle grinder wheels safe?

This depends on the experience you have with how to operate the machine. Moreover, you need to test new grinding wheels in a safe space before using them. In addition, to guarantee your safety, ensure you place the workpiece well so that every dirt flies downwards. Also, you should avoid taking wheels close to the edges because they may kick back the object.

What’s a soft start?

There are angle grinders that burst into potent force any time you switch them on. This makes your hands strain when controlling the grinder to direct it to the workpiece.

However, soft start technology helps in overcoming this issue. The tool will start slower as it increases to the correct speed to deal with the task. Soft starts also help in reducing user fatigue.

How can one remove the disc from an angle grinder?

Removing a disc depends majorly on the tools at hand and your preference. As a safety measure, you should switch off the grinder’s power before removing the disc and check the disc arrow when installing.

What types of angle grinders are available?

There are two significant kinds of angle grinders. These are corded grinders and cordless grinders. The best corded angle grinder gets its operating power directly from an electric source using a power cord. Moreover, this corded grinder is suitable for use in places where you can access power. Thus, it’s only suited for jobs in enclosed spaces, including offices or homes. In addition, these corded models give the operator higher power output whenever in use. 

However, cordless power tools use batteries that need recharging after use. This equipment can be used even in a remote place with no power when the battery is charged. Furthermore, cordless angle grinders come with limited or reduced output, depending on the batteries utilized.

Can one cut concrete using an angle grinder?

Yes. An angle grinder can cut concrete though it should have the right blade. Moreover, more concrete projects need a segmented diamond blade.

Can one use an angle grinder to cut through metal?

Some different blades or discs are compatible with best angle grinders. These discs are for use on various surfaces. There are blades or discs suitable for cutting metal and other hard surfaces. You can then use a polishing wheel to polish a surface. Discs for cutting metal are thinner.

Conclusion

The best angle grinders are versatile handheld tools. You can use them for many things, including cutting metal, removing rust, polishing surfaces, sharpening, etc. When buying an angle grinder, check its power outlet, motor speed, comfort, safety precaution, soft start, etc. There are also grinders with variable speed settings. The motor auto changes the rate depending on the task. 

All the angle grinders on our list are comfortable and safe to operate. So why haven’t you started that project yet?
