Buying Guide

When looking for the best variable speed angle grinder, there are several factors to consider. We have compiled a list of features to help you choose the right product for your needs.

Power

The power of an angle grinder is measured in amps. The higher the amps, the more powerful the grinder will be. However, a higher amp rating also means the grinder will be heavier and more expensive. We recommend choosing a grinder with a power rating between 7-10 amps for most applications.

For general purpose grinding and cutting, a 4.5-5 inch disc is sufficient. For larger projects, a 7-9 inch disc may be more appropriate.

Safety Features

Angle grinders can be dangerous if not used properly. Look for grinders with safety features such as a safety guard, lock-off switch, and anti-vibration handle. These features can help prevent accidents and make the grinder easier to use.

Accessories

Many angle grinders come with accessories such as grinding wheels, cutting discs, and sanding discs. Consider the type and quantity of accessories included with the grinder when making your purchase.

By considering these factors, you can choose the best variable speed angle grinder for your needs. Remember to always follow proper safety procedures when using an angle grinder.
