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.
How to Choose an Angle Grinder
If you are looking to buy an angle grinder, there are some things that you should consider before buying one. These tips will help you decide whether an angle grinder is right for you.
1. Safety First
Safety is always important. Make sure that you wear safety goggles and gloves when using an angle grinder. Also, ensure that the area where you are working is well lit.
2. Size Matters
Before purchasing an angle grinder, think about how large the area that you need to cut is. Do not purchase an angle grinder unless you have enough room to store it.
3. Power Source
An angle grinder requires electricity to run. Therefore, you must have access to a power source.
You may find that an angle grinder is cheaper than other types of power tools. However, you may also find that they cost more over time.
5. Material Type
Angle grinders are great at cutting metal. However, they cannot handle very soft materials like wood, paper, cardboard, etc.
Angle grinders come with different accessories. For example, some models come with a dust collection system, which helps to keep your workspace clean. Some include a storage case, so that you can carry your tool around.
When you purchase an angle grinder, make sure that it has a warranty. This will protect you in case something goes wrong with your machine.
Keep your angle grinder oiled regularly. You can use a grease gun to apply oil to the blade. It is recommended that you change the blades every two years.
9. Cutting Speed
The speed at which you operate your angle grinder determines how fast it cuts. When you are operating an angle grinder, try to maintain a constant speed.
10. Noise Level
The noise level of an angle grinder depends on the model that you choose. However, most models produce a loud noise. If you want to avoid disturbing others, then look for a quieter model.
Durability is essential when choosing an angle grinder. Look for a durable model that has been designed to last.
Weight plays a big role in deciding what kind of angle grinder you should get. The heavier the model, the harder it will be to move around.
Versatility is another factor that you should take into consideration when selecting an angle grinder. Consider the size of the area that you plan to cut. Will you be cutting small areas or larger ones?
14. Storage Space
Storage space is another thing that you should consider when shopping for an angle grinder. How much space do you have available to store your new tool?
Warranties vary from manufacturer to manufacturer. Therefore, you should check out the warranty information on each product that you are interested in.
What is the difference between an angle grinder and a circular saw?
A circular saw is similar to an angle grinder. They both require electricity to work. However, there are key differences between them.
Circular saws usually have replaceable blades. Angle grinders do not.
Circular saws are typically smaller than angle grinders.
Circular saws tend to be less expensive than angle grinders. However, if you buy a quality circular saw, you can expect to pay more money.
Circular saws require a lot of power. In fact, they need more power than angle grinders. If you are looking to cut through hard materials, such as concrete, then you should probably go with a circular saw instead of an angle grinder.
Safety features are important when using any type of power tools. An angle grinder does not offer many safety features. On the other hand, a circular saw offers several safety features.
Circular saws come with various accessories. These include things like grinding wheels, abrasive discs, and sanding pads. Angle grinders do come with their own set of accessories.
An angle grinder produces a louder noise than a circular saw.
8. Maintenance and Repairs
Angle grinders are easier to maintain and repair. Circular saws may require professional help.
Circular saws weigh significantly less than angle grinders. This makes them easier to transport.
Circular saws can cut almost anything. You can use them to cut wood, metal, plastic, stone, tile, glass, and even drywall. Angles grinders cannot cut everything.
What can you not do with an angle grinder?
You cannot use an angle grinder to cut concrete, brick, asphalt, or mortar. It would also be difficult to use an angle grinder on large surfaces.
How long can I use my angle grinder before it needs maintenance?
There is no specific time limit. However, you should make sure that your angle grinder is working properly before using it. Otherwise, you could damage your machine.
Can you use an angle grinder on cement?
Yes. You can use an angle grinder safely on cement. The only problem is that you might have to clean up some residue after you finish cutting.
Can an angle grinder cut steel?
Yes. You will want to use a diamond-coated blade to ensure that you do not scratch the surface of the steel.
If you are looking for a versatile tool that can be used for multiple purposes, then an angle grinner is the right choice for you. It is great for cutting materials such as wood, concrete, tile, etc.
