Best Angle Grinder | UK Guide | 2021
Angle grinders are among the most versatile power tools on the market. These heavy-duty tools can be used for a variety of cutting and sanding applications, while you an also use them to undertake more refined shaping work. They are also designed to be used with a variety of materials types, ranging from soft woods to hard concrete.
Unlike bench grinders, angle grinders are operated by hand, allowing you to really get stuck into your work pieces with no restrictions. Need a power tool that can undertake demanding grinding and cutting tasks? Our guide explores the essential criteria you should be looking to fill when selecting the best angle grinder.
Angle Grinders Applications
Angle grinders are a handheld cutting and grinding tool that feature a gearhead fixed at a 90-degree angle. This gearhead houses a removable disc that can be made of various materials and come in a variety of thicknesses. As the cutting and grinding discs are located at the very end of the tool body, you are not limited when it comes to carrying out work on your materials. This makes them ideal for undertaking finer detail work. When used for grinding applications, an angle grinder can be effective at softening sharp metal edges.
They can also be used for sanding applications. If you need to prepare a surface quickly, an angle grinder is a good tool to reach for. You will however need to use a sanding pad to ensure the rapid movement of the wheel disc does not cause any excessive damage to your materials. In sanding mode, angle grinders are very good at smoothing our rough finishes, or getting rid of residual debris and old paint layers.
You can also use an angle grinder for cutting tasks. Again, you will need to make sure you purchase a suitable cutting disc beforehand. Some cutting discs are suited to slicing through wood and masonry, while others can be used for more brittle materials like PVC and plastic. More robust cutting discs can be used for very tough materials like metal and concrete.
If you need to polish off a surface for a smooth finish, you can also utilise an angle grinder for polishing tasks. Polishing discs can be bought specially and provide a superior finish in a fraction of the time it would take to carry out the work by hand.
Finally, angle grinders are useful for sharpening the edges of some tools. They are very effective at sharpening bladed tools, including chisels, although you will need to be careful when carrying out sharpening tasks. Operating your angle grinder on a lower speed setting is definitely a must when sharpening tools.
When choosing an angle grinder, go for a brushless motor whenever you can. An angle grinder requires plenty of power, so an efficient brushless motor is the ideal fit. With a brushless motor, you also do not have to worry about replacing brushes. This is not only convenient and saves you time, it also negates the expense of having to purchase brush replacements. A brushless motor will also usually result in longevity, with cooler operation reducing the strain on the interior of your power tool.
Safety is something you should be paying attention to when shopping for an angle grinder. A kickback brake is definitely something you want to have on your side when using an angle grinder. These braking systems mean that your tool will automatically stop when it finds itself stuck in tough material. This not only prevents the angle grinder from pulling free from your hands when it is running, but also eliminates the chance of you suffering a nasty injury.
If you are using an angle grinder for a prolonged stretch of time, vibration can take its tool and lead to fatigue. If your angle grinder is a powerful one, excessive vibration can leave your hands and wrists feeling exhausted. This is not only uncomfortable, but can also affect how well you can handle the tool. This can impair your accuracy when working and, in the worst case, lead to an injury.
Variable Speed Control
If you plan on working with multiple types of materials and want to undertake a variety of grinding, sanding and cutting tasks, variable speed control is essential. Variable speed control gives you full control over the speed your discs are rotating at. A pressure trigger that control disc speed will make life incredibly simple, allowing you to quickly adjust the speed of rotation. This not only allows you to maintain maximum precision as you work, but it also allows you combat overheating if your angle grinder does not have any integrated vents.
