Frequently Asked Questions (FAQ)

What is the best 115mm angle grinder?

The best 115 mm angle grinder for the money is the DEWALT DWE402.

It uses a 4-pole motor which is great for industrial usage since there are no brushes to wear out.

The grinder is made from a strong and durable cast aluminum housing and comes with two grinding wheels, a cutting wheel, and a wire wheel.

There is a dust port and the grinder comes with a wire lock safety guard that will help to protect the user manually and an electric brake.

What is the best 9 inch angle grinder?

The 9-inch angle grinder should generally be the only angle grinder you will need or want for most home improvement projects, including the ones that I’ve listed below, until you can afford a a bigger and more powerful motor.

The 9-inch angle grinder will cut, grind, and polish just about everything that you will need it to.

What size angle grinders are there?

Usually, the smaller the angle grinder, the easier it is to use. Smaller grinders usually have a more confined space for your hands and are harder to operate.

On the other hand, larger grinders give you the ability to connect your tool to your work. This makes the whole process of grinding smoother.

If you are going to be using it for longer time in a day then the larger angle grinder is of great use.

How do I choose an angle grinder?

The first thing that you have to match with the grinder is the disc of your choice. It is the disc that holds all of the cuttings and does most of the work.

The discs are either made of aluminum oxide, hardened steel, or silicon carbide. All of them are great but serviceable in different applications.

Some discs may include a resin bond while others have a fibre backing. Whatever the case, remember that the grit size, serviceable diameter and applications are the areas that you have to focus on.

The disc spindle should be one that is on its own and not a shaft with other types of attachments on it. It is most effective when it has discs that are reversible featuring crown and flat sides. They are the most efficient angle grinder discs and will give you satisfactory service.

Conclusion

This is a whole lot of power in one small package. The grinding wheel reminded me of an old school steel file, so that was my biggest fear- the wheel wearing out over time and breaking. This tool does not disappoint. It is very solidly built. I would recommend, if you purchase an angle grinder, buy a grinding wheel that is made to withstand high revolutions per minute. As an added bonus this angle grinder is completely equipped with a guard.
