9 Angle Grinder Uses & How to Use It Safely

Angle grinders are versatile tools that can be used for a variety of purposes. They are also very useful for DIY projects around the house.

Angle grinders are designed to cut metal or stone. The blades are usually made from hardened steel and they are sharpened at both ends. Blades wear out over time and eventually need replacing.

What is an angle grinder?

An angle grinder is a handheld tool with two rotating discs, one above the other. Angle grinders have many different attachments which allow them to be used for a wide range of tasks.

The lower disc has a number of cutting edges and it is attached to a motorized shaft. The upper disc is fixed on top of the lower disc and it has a grinding surface. When you turn the handle of an angle grinder clockwise, the lower disc spins counter-clockwise. This allows the user to rotate the blade in order to cut through material.

The angle grinder’s main advantage is its versatility. It can be used for a wide variety of jobs including cutting wood, concrete, plastic, plaster, tile, brick, masonry, drywall, etc.

Uses of Angle Grinders

There are many reasons why people use angle grinders. Some common uses include:

Cutting wood – An angle grinder is perfect for cutting wood because it makes quick work of this task. You can easily remove small pieces of wood without having to worry about damaging your table saw or circular saw.

Cutting concrete – Concrete is hard but it does not take much force to cut through it. With an angle grinder, you can quickly make cuts into concrete walls and floors.

Cutting tile – Tile can be difficult to cut when using power tools such as a drill or hammer. However, an angle grinder is ideal for making clean cuts into tiles.

Grinding concrete – If you want to smooth out uneven surfaces, then an angle grinder is the best way to go.

Grinding bricks – Bricks can be tricky to cut if you do not know what you are doing. A grinder will help to get rid of any rough edges.

Cleaning up concrete – Concrete is often used to build sidewalks, driveways, patios, etc. However, after a while, these areas become dirty and dull. Using an angle grinder, it is easy to cut away old concrete and replace it with new fresh concrete.

Cleaning up asphalt – Asphalt is another type of pavement that needs cleaning up. Use an angle grinder to cut away old asphalt and expose the fresh asphalt underneath.

Removing paint – Paint comes off just like concrete and asphalt. However, removing paint is easier than removing concrete or asphalt.

Removing rust – Rust can be removed by sanding it down. However, an angle grinders can make short work of this job.

How to Use an Angle Grinder Safely

To use an angle grinder effectively, you must first understand how it works. Here are some tips to keep in mind:

Always start with the safety precautions. Always wear eye protection, gloves, and protective clothing. Make sure that you follow all manufacturer instructions before operating the machine.

Use the right size blades. There are different sizes of blades available depending on the model you choose. Choose the appropriate sized blade for the job at hand.

Make sure you are holding the handles correctly. Hold the angle grinder so that the handles are parallel to each other. Do not hold the angle grinder so close to your body that you cannot see the controls clearly.

Make sure you have adequate ventilation. To avoid inhaling dust from the air, always ensure that there is ample airflow around the area where you are working.

Know your limits. Know how much weight you can safely handle. Never exceed the recommended weight limit.

Keep the motor cool. The motor should never be allowed to get too hot. This could damage the motor. In addition, the heat generated by the motor may cause burns.

Keep your hands dry. Make sure that you do not allow water to drip onto the motor. Water can ruin the bearings and cause them to seize.

Be careful when changing blades. When replacing blades, make sure that you change them slowly. Otherwise, you risk damaging the motor.
