Cordless Angle Grinder Buyer’s Guide
Battery powered angle grinders require powerful motors to tackle tough jobs such as cutting steel or paving slabs. In general the more powerful the motor, the more rpm and the more heavy duty tasks can be taken on.
More expensive battery angle grinders have brushless motors. These are more efficient and last longer than brushed motors because they only produce the power required to complete the task. A brushless motor also eliminates friction so runs cooler, more quietly and with less vibration than a brushed motor. Brushless angle grinders like the Makita DGA 504 Z Angle Grinder have a longer lifespan, too.
Cordless 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.
Battery angle grinders like the Bosch Professional GWS 18-125 V-LI Cordless Angle Grinder can be used for a wide variety of tasks. Cordless grinders 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 battery powered angle grinders 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.
Cordless 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 angle grinder tool if it does not already come with these.
Other angle grinder features to look for include a slim profile, a soft grip handle, an adjustable handle, tool-less disc changing and overload protection.
Many battery angle grinders come as bare tools. This is because you can use the battery on a range of tools so don’t necessarily need a new battery with every tool you buy. Cordless angle grinders are power-hungry tools, so it is worth buying more powerful batteries if you want to be able to use the tool for reasonably long periods between charges.
Some cordless angle grinders like the Ryobi R18AG-140S 18V ONE+ Angle Grinder and the NoCry 20V 115mm Cordless Angle Grinder come with a battery, charger, a range of discs and a carry case which provides everything you need to get started on projects straight away.
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 angle grinder 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 damaged as this 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 angle grinder. You may also need to wear ear protection and a dust mask depending on the materials you are working with.
You should always ensure that the handle and disc guard are in the correct location and securely fixed before starting work.
How do I use an angle grinder?
You should always follow the instructions for your specific angle grinder 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 angle grinder securely and switch it on. Let it come to full speed before applying it to the surface of the material.
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.
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. We would recommend either the Dewalt DCG405N 18V XR Brushless 125 mm Angle Grinder or the Milwaukee M18CAG115XPDB-0 18 Volt model, because of their brushless motors, excellent safety features and comfort when in use.
