How to Select the Best Angle Grinder

There are two types of angle grinders, mainly corded and cordless. Before you go out shopping for this power tool, it is a good idea to rent out one and see how you like it. This will help you get a sense of the qualities and key features to look for and then select the best angle grinder. Here are the key features to consider when shopping for angle grinders:

Speed

An angle grinder’s speed determines its efficiency. The speed is always calibrated at no-load measures. This means that if you see a rating of 11000 rpm for a grinder, it was measured when the grinder wasn’t held across any surface.

Most home-use angle grinders have speeds ranging between 8000 rpm and 12000 rpm. These days, you can select grinders with speed-adjustment features but you must be prepared to shell out more money for them.

Safety

Safety features of a grinder include a safety clutch and plastic sheath or casing that prevents metal filings from flying all over the place. The most important safety feature is kickback prevention. It is seen in powerful grinders which are used for tough jobs that can cause jarring kickbacks.

Kickback is annoying and also quite dangerous as it can lead to serious injuries. By paying a bit extra for grinders with adjustable guards, you can enhance the grinder’s accessibility without compromising safety.

Ergonomics

User comfort is of utmost importance when it comes to selecting any power tool. The same is the case with an angle grinder. Choose a unit with a removable side handle that can be used comfortably by left and right-handed users. The handle should allow a firm grip for greater control.

It should also be thin so as to prevent pain and user fatigue. The weight of the grinder is an important consideration here. Lightweight grinders allow you to lift them up easily for prolonged work on overhead applications.

Extras and Accessories

Some extras are just nice to have in any power tools. For example, some grinders come with swappable batteries that you can use for any of your power tools. This can ease the projects that need drills, saws, and grinders. The grinder should also come with a protective case that is durable and protects the grinder when it is not in use.

Many grinders come with accessories like brushes, cutting and grinding wheels, spanners, sandpaper, different discs/wheels for cutting wood, steel, and concrete etc, wrenches, and flap discs. In case you use a corded model, the cord of the grinder should also be long enough to enhance its portability.
