Buying Guide:

Whether you’re a professional worker or a just a DIY enthusiast who loves to work on creating new things, therefore, we suggest you invest in the best angle grinders to complete your basic home tool kit. The angle grinder, as already mentioned, is involved in a variety of operations, i.e. grinding, cutting, polishing and sharpening as well.

Here in this guide, we’ll move you through all the factors and attributes that you need to consider before buying the best angle grinders for safe and efficient work experience.

Factors You Need To Consider:

Corded or Cordless:

Most of the angle grinders are corded, but now some of the brands are launching their cordless angle grinders as well. Both of these have their own perks, and it depends on your job type to choose the best-suited. Whenever you’re working in the right places or the places that are far away from the power plug, going for the cordless models will be the right choice.

On the other hand, if you can manage to have the wire extensions and the operations are very time consuming, then you need to go for the corded ones as the battery won’t last long.

Wheel Sizes:

Wheel sizes correspond to the power of angle grinders. The bigger the size, the more powerful is the device. While when it comes to the smaller wheel size, the angle grinder’s precision will be higher. Therefore, again it depends on the job type which you need to perform. If you’re going to deal with the tight places then choosing the compact one will be the right choice.

However, dealing with more substantial objects that need more power to be cut or polish, you need angle grinders with larger wheel sizes.

Speed or RPMs:

Speed can affect the overall performance of the angle grinders. Most of the best angle grinders have the RPMs ranging from 1000 to 10,000. Faster the speed, the less time consuming the job will be. However, an untrained expert needs to keep his hands on the lower speeds first to avoid any accident. Also, make sure to buy an angle grinder with variable speed options.
