Best Angle Grinder Has Some Factors to Look Out For
You cannot just go to a shop or any online marketplace and randomly choose a grinder. Angle grinders can be classified based on their features, power sources, disc types, size, speed, etc. Also, some of them have some features which are simple but essential. The following factors are notable enough for consideration while shopping for the best angle grinder.
Disc Size
The angle grinders come in different sizes. You can change the disc according to your field of work. But first, you must be sure if the grinder allows the disc size you are trying to work with. The angle grinder disc can also be called a ‘wheel.’ There are many discs available. But the most commons are 4.5” and 9”.
Discs with large sizes are comparatively more compatible for heavy-duty or industrial work. The grinder size increases with the disc size. That makes them more stubborn to manage efficiently.
Speed
The grinder’s speed is measured in revolutions per minute (rpm). We have mentioned earlier that this tool comes in different sizes. There is a fact that is worth remembering that smaller angle grinders have high rpm comparatively. The number varies between 5000 – 11000 range, and many of them come with an excellent feature of variable speed controls where you can engineer the speed as per your need. The maximum speed is lower in the case of larger angle grinders. Between 5000 – 8000 rpm range.
There is a safety factor to notice that the speed the company states is the maximum speed when the disc is just rotating in the air—not doing anything like grinding, cutting, polishing, etc. The disc becomes hotter proportionally to the speed. There is also severe caution not to operate the disc at speed more than the stated one on the disc, which can make them shatter and cause intense injury to the people around it.
Power Source
Based on the power source, angle grinders can be divided into two sections. Cordless and corded. You have to choose between them. To determine the best angle grinder, you must know both types. Each type carries its benefits and drawbacks.
- Corded Angle Grinder – Corded angle grinder assures that you may not fall short of power. As long as the tool is connected to an outlet, you should not fear running out of energy and completing your task. But of course, you have to ensure the outlet is powered electrically. The negative side of a corded angle grinder is that there is a chance for you to fall short physically unless you have an extension cord.
- Cordless Angle Grinder – Convenient angle grinders are used in multiple worksites worldwide. They are very versatile. And they are extremely friendly to carry them wherever and whenever you want without worrying about an electrical outlet. The most concerning disadvantage is that the cordless angle grinder will not provide you with the same sheer power as the corded one, and it’s not impossible that the battery won’t run down. By having two batteries, you can solve the battery problem.
Safety Features
If you want to choose the best angle grinder, it should have some safety features. The handguard is a significant one. It is a simple but essential safety factor. A handguard provides protection for the operator from sparks and relics. This handguard comes in two states. Fixed and movable are the two states. Of these two kinds, movable is popular among users as it provides an extra benefit for both right and left-handed users.
There is another vital safety feature, which is known as a kickback brake. This feature ensures automatic stopping of the wheel while binding. Some advanced angle grinders include a two-stage trigger. This two-stage trigger safety feature is safer as there is another safety switch that the operator must turn off before taking action.
Smooth Start
‘Fast & powerful’ is the perfect phrase if you want to describe the best angle grinders in short. Because of the power, they can recoil a little when they start. And if they are large and heavy, the recoil sometimes turns dangerous to handle. As a result, they can jump on hands and cause serious injury to the operators or users.
But thanks to modern technology! This recoil problem is not a headache anymore. To fight the angle grinder’s recoil, smooth-start technology is used to reduce the power output to the motor while it is starting. Then slowly increases the power until the angle grinder reaches its peak. Thus, that smooth-starting system easily controls this powerful tool, ensuring no injury.
Safety Issues For an Angle Grinder
Are you familiar with drill machines? Drill motors rotate at 700 – 1200 rpm (revolution per minute). In comparison, the grinders spin at a scary speed of 10000 – 11000 rpm, which is about 10x times faster. A big reason to be careful and worry about the safety of angle grinders. But here, we have referred to some easy but important and helpful safety precautions that may keep you safe.
- Always use a face shield and gloves while operating an angle grinder.
- Don’t be fool enough to detach the handle. Always maintain a firm grip using both hands and attach the handle.
- Don’t hesitate to use the guard if it is possible.
- When you are changing discs, don’t forget to unplug the grinder.
- After changing the new discs, run that in a safe area for some time (about one minute) just to be sure that the new disc isn’t faulty.
- Be careful with the debris, so they may find the earth instead of injuring anyone.
- You shouldn’t allow any spectators near you. But if you have any, they also should use the safety glasses.
- Make sure the sparks and any flammable materials never reach each other.
- There is no other option except to choose the right disc for the right task.
- Make sure that the grinder is switched off before connecting it to a power supply.
- Never use a faulty angle grinder.
- Keep the children away from this tool.
Always remember some people are waiting for you to return home safely. So, safety first. We care about you.

Place the rotating disc at the correct cutting or grinding point of the material you want to cut or grind.
At your finishing, release the power switch. Here you must maintain some safety factors. Don’t put the grinder away until it finishes rotating after you release its power switch. After you have completed your work, be careful with the disc, as it will still be hot because of the constant friction. Unplug the angle grinder from the cord or the battery after you are done.
Is it possible to get a battery-operated angle grinder?
We have mentioned before alongside the corded angle grinder, the cordless angle grinder, which is battery operated, is also a very popular and wise choice according to the suitable projects.

Then you need to maintain the safety factors like protective goggles and ear protection as it makes a huge sound while cutting metal and wear closed shoes. Also, do not wear loose clothes and avoid slippery or wet standing places.
Hold the grinder firmly and turn on the tool after marking your cutline with a chalk or marker. Wait for it to reach the maximum speed. Then carefully place the rotating wheel against the initial point of your cutline.
Then follow the procedure described above to answer the question “How to operate an angle grinder?”
Following these rules, you can cut the pavers with an angle grinder. But you must ensure that you have chosen the right disc for the right job.
How to fit a new angle grinder disc?

Remove the nut that holds the disc using the spanner provided with the grinder; remove the nut that holds the disc. Then replace the new disc and the nut bolt using the same spanner. Or you can use the spindle lock system, in case it features.
How expensive is an angle grinder?
You have to spend from 30$ to over 200$ if you want to add the best angle grinder for you to your collection box. But price range between 70$ to 100$ is more common for an angle grinder.
