Cordless Angle Grinder Buyer’s Guide

Motor

Angle grinders need a powerful motor to effectively complete tough jobs such as cutting steel or paving slabs. However, it can be difficult to know which angle grinder has the most powerful motor, because there has are many ways to measure the power.

A brushless motor will be more efficient and last longer than a brushed motor. This is because it only produces the power required. A brushless motor also eliminates friction so runs cooler, more efficiently and quietly and with less vibration than a brushed motor. Brushless versions like the Makita DGA 504 Z Angle Grinder have a longer lifespan, too.

Another way to judge the power is to look at the revolutions per minute (rpm) that the tool provides. In general, the higher this number, the more powerful the tool.

Safety features

Angle grinders have a range of features to make them safer to use. These can include safety switches, accidental restart protection, electronic brakes and safety guards.

Usage

Angle grinders like Bosch Professional GWS 18-125 V-LI Cordless Angle Grinder can be used for a wide variety of tasks. They can cut materials such as metal, tile, stone, masonry, paving slabs and concrete. They can also rout out mortar and remove paint and rust. In addition, they can be used to grind, polish and sharpen.

This means they are extremely handy for a range of DIY tasks and household maintenance. They are also an essential part of the tool kit for construction workers, landscape gardeners, mechanics, welders and plumbers.

Other Features

Angle grinders are available in a range of sizes. The most common are 115 mm and 125 mm. You will need to purchase the appropriate size discs for your tool if it does not come with these.

Other features that are handy include a slim profile, a soft grip handle, an adjustable handle, toolless disc changing and overload protection.

Batteries

Many angle grinders come as bare tools. This is because you can use a battery on a range of tools so don’t necessarily need a new battery with every tool you buy. Angle grinders are power-hungry tools, so it is worth buying very powerful batteries if you want to be able to use the tool for reasonably long periods between charges.

Other Accessories

Some angle grinders like Ryobi R18AG-140S 18V ONE+ Angle Grinder and NoCry 20V 115mm Cordless Angle Grinder come with a battery, charger and a range of discs and a carry case which provides everything you need to get started on projects straight away.

Safety

Angle grinders are very powerful tools and potentially dangerous to use. However, following some simple safety precautions ensures that you can benefit from the power and versatility of these tools without injury. You should always read the instructions that come with your tool carefully before use.

It is important to ensure you use the right disc for the task and follow the specific procedure for the job. For example, you may need to use water as a lubricant when cutting some materials. If you do not follow the correct procedure you increase the risk of pieces of the material or the disk flying off and causing damage or injury. Always check discs for damage before use. You should never use a disc that is at all damaged as these can be extremely dangerous.

Angle grinders can throw up a lot of debris when used so it is essential to wear safety goggles, or better still a face mask when using the tool. You may also need to wear ear protection and a dust mask depending on the materials you are using.

You should always ensure that the handle and disc guard are in the correct locations and securely fixed before starting work.

FAQ

How do I use an angle grinder?        

You should always follow the instructions for your specific tool. However, the following is a general guide to using angle grinders.

When using a grinder, make sure you pick the right attachment for the job and use that attachment correctly. You will need a cutting wheel for cutting metal or tiles, a grinding wheel for sharpening tools, a tuckpointing wheel for removing old mortar or a wire brush attachment for cleaning off rust or old paint.

You may need to clamp the item you are working on if appropriate.

Don your safety equipment and ensure no bystanders are nearby.

Grasp the tool securely and switch it on. Let it come to full speed before applying it to the surface.

Apply the tool with light pressure when cutting or grinding. When cleaning or sanding, move the grinder around to prevent gouges.

Ensure the wheel has come to a complete stop before putting your angle grinder down.

Conclusion

Angle grinders are powerful tools that make light work of tough jobs such as cutting metal or paving slabs, removing rust and paint and sharpening tools. I would recommend the Dewalt DCG405N 18V XR Brushless 125mm Angle Grinder because it features a brushless motor, has excellent safety features and it is light and comfortable to use.
