What Is An Angle Grinder
An angle grinder is also known as a disc and a side grinder is a power tool used for polishing and abrasive cutting.
Nowadays, there are now different attachments and cutters. The angle grinder can also be powered by compressed air, a petrol engine, or an electric motor.
For easy operation, an angle grind should have two side handles and an adjustable guard. Some of the materials where an angle grinder is needed would be disc, back pad, sanding disc, and sanders.
Uses Of An Angle Grinder
When grinding the mortar, you need to remove the old mortar first. But If you still prefer using the old one, then you can use the angle grinder with a tuck-pointing diamond wheel.
Another use of an angle grinder is that it can be used to sharpen the blades of lawnmowers, shovels, and other tools.
As you all know, the tools’ blades can become bland after quite some time. So instead of buying a new blade, it would be best just to sharpen them using an angle grinder.
Cleaning And Polishing
If you have metals at home, you can use the angle grinder to clean and polish them. You can get dirt and rust off the metal using this power tool.
It is also advisable to regularly clean them because it might get challenging to get rid of the rust and mud if you let it sit on your metals for an extended period of time.
You can also use an angle grinder to cut metal, concrete, stone, and tiles. But, for your safety, you need to make sure that you are careful.
The best thing that you can do is to use a strong blade when cutting and make sure that the material that you’re cutting is on a surface that won’t move.
How To Change Angle Grinder Disc
The first thing that you need to do is to disconnect the power so you can remove the disc using a factory spanner. The factory spanner comes with a grinder, and you can use this to remove the disc.
A spanner will usually look like a traditional wrench, while the other looks like a two-pronged fork. Using the prongs, insert them into the holes in the bolt, which is between the angle grinder and the disc.
Secure the bolt using the wrench spanner and start turning the pronged spanner in a different direction and make sure that the other wrench is securing the disc.
You might also see a button on the side of the grinder. You can turn the nut, and the disc will be removed from the tool.
How To Use An Angle Grinder
To use an angle grinder to clean caked-on cement, dirt, and rust from your garden tools, you need a wire cup. Attach the wire cup on your angle grinder and make sure that you secure the tool using a vise or clamps.
Start cleaning the tool away from the tool and make sure that it’s not on end. This might cause the angle grinder to kick back and can cause injuries and such.
To use an angle grinder to cut on bolts, rods, and bars, you need to attach a metal cutoff wheel to your angle grinder.
Prop the long car of the rebar to the side and securely hold it. Start cutting through the metal and let the tool’s weight do the work.
Let the short end drop so freely that you can avoid the blade from binding.
Start clamping the blades in your workbench or a vise using a hand clamp. Start orienting the grinder and ensure that the blade guard I adjusted deflects the sparks from your body and face.
Always align the grinding wheel on the blade with an angle. Start with the grinder process and steadily grind the wheel across the blade. Of course, make sure that you’re applying light pressure.
Can An Angle Grinder Cut Stone
Yes, angle grinders have the ability to cut any type of stone. But make sure always to wear protection and choose the right quality of disc to avoid your grinder from kicking back. This can cause damage to your grinder and the material that you’re cutting.
Tips On Choosing An Angle Grinder
Kind of Angle Grinders
The first thing that you need to do is to check the kind of angle grinder that you want to purchase.
There are versatile and maneuverable angle grinders, which are both excellent tools for sharpening, cutting, and smoothing. So choose something that you will be able to use.
Size Of Angle Grinders
The next thing that you need to do is to choose the size of the angle grinder that you need. If you often handle large jobs, then a bigger angle grinder will do.
Remember that you can determine the size of the angle grinder by its disc and not by its length.
There are also small grinders for smaller tasks, wherein the grinders can spin at a faster rate. This can help polish and cut metals if needed.
Size Of The Disc
Just the like angle grinder itself, the size of the disc is also important. If you are going to choose a larger disc, then it can provide a more powerful motor.
If you need precision, then you can opt for a small-size disk which is perfect for a standard grinder.
Power Of The Motor
Grinders have different amp ratings, wattage, and voltage. The most common power ranges from 110 to 230 volts AC, while the wattage ranges from 500 to 2,500 watts. The amp can range between 4 to 15.
The speed rating typically ranges from 5,000 to 10,000 RPM or revolutions per minute. This will help you know if the angle grinder that you purchase can cut, sand, and grind when needed.
With all the above being said and with the two reviews on angle grinders, you have surely considered which brand you want to choose. Using an angle grinder will make things easier for you when cutting and polishing certain materials.
Just make sure to take extra precautions when cutting harder materials, including stones to avoid accidentally harming yourself and damaging your tool and material.
