This Milwaukee tool, like its name, is a light-duty angle grinder. It is useful for smaller, lighter projects. It would be advised that you purchase this only if you are not a professional. However, its durability and easy-to-use factor is enough to lure amateurs.
This operates as a cutting and grinding tool, hence a perfect choice for your house and its small needs.
My Verdict
If you ask me which tool I like the most, it would be Dewalt DCG418X1. It is efficient, powerful, durable, and fast. The battery technology comes with a greater runtime. Also, with just a push of the button, you can choose between a 4 ½-inch wheel and a 6-inch. Although this is a cordless angle grinder tool, it gives you the corded power tool performance.
Buying Guide
An angle grinder is a versatile tool that can be used for multiple metal fabrication tasks. And therefore, when purchasing an angle grinder, make sure to select an appropriate one for the task and site requirements. Here is a criterion to follow while buying an angle grinder:
Disc Diameter
When choosing an angle grinder, the disc diameter is a major determinant. The machine’s cutting depth increases as the disc diameter increases. Angle grinders with larger disc diameters are usually more powerful. They are ideal for deep cuts and polishing and buffing wider regions.
Grinder discs rotate at a faster speed in smaller grinders, making them easier to handle. Smaller angle grinders cannot cut as deeply as larger ones, and their discs must be replaced more frequently due to a higher wear rate.
The most common and popular disc diameter for an angle grinder is 4.5″. Many consider it to be the most adaptable size for a handyman’s toolkit. That isn’t to say angle grinders can’t be bigger; they can be as big as 7 or 9 inches.
It’s also critical that you select the disc size based on the precision of the work you’re doing. For grinding applications that demand more precision, a grinder disc with the size of a pneumatic grinder would be preferable. Before purchasing a grinder, you should think about the disc kinds that come with it, or at the absolute least, the disc types that are compatible with it.
Wattage
Angle grinders must be considered for their power wattage as well as their rotational speed while buying one. The rotational speed is measured in RPMs (rotations per minute). Electricity, compressed air, and gasoline are all used to power the angle grinders.
Being aware of the power source aids in selecting the appropriate grinder for the job. Higher watts provide more power for cutting rigid materials such as thick steel. A higher wattage is also recommended if the grinder will be used for extended periods.
Angle grinders come in 240v and 110v versions (for site work), and smaller grinders are now available in 18v cordless versions. Some 36v and 54v cordless angle grinders function similarly to larger, mains-powered tools. Make sure to choose an angle grinder with a motor that has enough power for the job.
Speed
Angle grinder discs spin at speeds that start from 5000 revolutions per minute. Keep in mind that you have a more effective angle grinder if it has a higher number of revolutions. There’s also the question of load speed to consider. Load rates typically range from 700 to 12000 rotations per minute.
Grinders with single and variable speeds are available. Variable speed angle grinders allow for more delicate work at lower speeds, but they usually come at a higher price range. Consider the motor’s rpm, which can range from 3000 to 11000. The amp could be anything from 5.0 and 13.0 amp.
Wheels, Handles & Spindle Lock
Diamond head wheels, grinding wheels, and cutoff wheels are examples of wheels used on angle grinders. Heavy-duty wheels allow one to manage challenging jobs easily. Another crucial feature of the angle grinder is its handle.
Consider purchasing a grinder with an adjustable handle. This allows the worker to operate with both hands while grinding and cutting. It should also have anti-vibration characteristics to make the tool easier to handle.
Make sure it includes an adjustable guard in addition to the adjustable handle. This guard is designed to keep the operator safe. It will safeguard you from flying debris and sparks generated during metal cutting and fabrication tasks.
A spindle locking mechanism in an angle grinder allows for quick accessory replacement. It can also help in its removal by prohibiting the wheel spindle from turning. However, the mechanism does include a metal nut to prevent the system from locking up while the tool is running.
Safety Features
Slow start is a feature on some larger angle grinders. It allows the motor to gradually ramp to full speed, preventing it from twisting in the beginning. An angle grinder’s anti-kickback mechanism causes it to cut out if the wheel gets jammed, which can avoid nasty accidents.. If the grinder has overheated or cut out and been left on, restart protection stops it from starting up again.
Some grinders have a paddle switch, sometimes known as a Dead Man’s Switch. It is a safety feature that ensures the grinder is held by two hands and stops the grinder from spinning if the switch is removed. These features often increase the tool’s price, but they will keep the operator and site environment safe.
Durability & Comfort of Usage
Angle grinders made of cast metal are extremely durable. Dust ejection system, for example, keeps dust and debris from damaging the motor and bearings. A few variables that can improve the ease of operation are:
- Ergonomic handle
- Vibration reduction system
- Handle settings
- and grinder size.
From a comfort aspect, a cordless angle grinder is undoubtedly the best angle grinder.
Keep an Eye on the Following Features
In Medium/Large Angle Grinders
- Overload safety protects the powerful grinder motor when it’s under a lot of strain.
- Larger angle grinders only have brush motors. So, an auto shut-off feature that alerts when the motor brushes need to be changed protects the tool.
- Side handles that are adjustable or removable allow utilizing the tool in confined locations.
- The vacuum attachment allows connecting the grinder to a vacuum to reduce trash and dust.
In Small Angle Grinders
- Angle grinders with brushless motors eliminate the need for brush changes. It allows cordless models to run more efficiently, cool down faster, and extend the tool’s motor life.
- When the tool detects a block, kickback brakes stop the wheel dead in its tracks, preventing the tool from ripping itself free from the grip.
- Vibration control prevents the operator’s hand from becoming numb. It alleviates the tool’s unsettling sensation during prolonged periods.
- Variable speed allows managing the disc speed, allowing it to slow down if heat builds up.
Storage
At last, I want to say something about storing the angle grinder. There are two main ways to do this:
- Keeping them in a drawer
- Haning them up, either upside down or by its spindle/disc.
The latter can be done on homemade or store-bought organizers. Whichever way you choose please make sure to keep the tools dry and that the discs are kept save from chipping or breaking.
Conclusion
For this round-up, I have considered dozens of angle grinders. And my overall favorite is DEWALT 20V MAX*-DCG413R2
You’ve read all the pros, cons, features, brand reputation, price, and power. Also, I considered its reviews from both DIY buyers and professionals to bring you a comprehensive review.
I hope you soak up this information and make the right decision to choose the best angle grinder. Good luck with finding your Best angle grinder
