Frequently asked questions on the best angle grinders
After getting all the information that you need, you probably have a few questions in mind regarding angle grinders. We answered some of the most common questions to help you find the answer to your question. Read on:
Q. what are the safety precautions when using an angle grinder?
When using an angle grinder, always wear a face shield, safety glasses, and gloves to protect you from sparks or debris. When changing the disc, make sure you unplug the grinder then run the new wheel in a protected area to make sure it is not defective. It is also essential to keep the sparks produced by the grinder away from flammable objects. Always clamp the workpiece while working. Lastly, store angle grinders properly away from the reach of children.
Q. can I use my angle grinder to cut concrete?
Yes. You can use an angle grinder to cut small concrete cutting work. It is more convenient compared to concrete cutting saws. If you want to cut concrete using an angle grinder, go for a turbo rim diamond blade as it is designed for cutting concrete. When cutting concrete, always observe safety measures to avoid accidents.
Q. What size of an angle grinder is best?
The size of the angle grinder you end up choosing should be determined by the project you are working on. However, the most popular size is the 4.5 inch which uses discs that are 4.5 inches in diameter and is a standard size for most projects.
Q. What is a flap disc for angle grinder?
A flap disc is an abrasive disk that is used for metal finishing. It is made of multiple overlapping flaps bonded to a central hub. Flap discs are better than flat sheets because they last longer and can be used even as the flaps wear away. The separate flaps also each attack the surface of the workpiece at different angles, thus avoiding the repeated identical scratches that are produced by flat sheets.
Q. does the weight of an angle grinder matter?
Sometimes, the weight of an angle grinder often seems insignificant but is essential, especially if you are considering a cordless one. Always buy a cordless angle grinder with the least possible weight. This will make it more portable and manoeuvrable, thus making work more accessible. A heavyweight angle grinder is most likely a sign of poor craftsmanship and wears out faster than a lightweight model.
How to Use an Angle Grinder
Final Word

When buying an angle grinder, always consider going for reputable brands as these have excellent quality and have stood the test of time. It is crucial to consider the source of the power of an angle grinder so that you enjoy versatility and portability. Corded angle grinders are most preferred for projects that don’t require a lot of movement or precision. For projects requiring precision such as smooth corners, always go for cordless angle grinders with a lasting battery.

You can select a small wheel for projects requiring exactitude or a large wheel when you need a smooth finish in very little time. In case you are a beginner; always go for a small wheel as it is easier to use.
Another vital factor to consider when choosing an angle grinder is its dust protection feature. You need a machine whose inner parts will not be exposed to dust, thus ruining the mortar.

Dusting an angle grinder after use and storing it correctly is a high maintenance practice that will make it serve you for long without breaking down.
