The fascinating feature for me about this tool was its speed settings. You can set it for different applications and different materials from metal to concrete to stone! But adjusting the environment according to purpose can be a trouble for beginners.

This device is made sturdy, compact, powerful, and lightweight to meet all grinding, sanding, or cutting purposes. Using this for overhead applications causes no fatigue. The side handle is leaned forward for more convenient operations.

The five wheels that are included in the package are useful for various applications. Besides, unlike other grinders, it comes in a robust hard case to make carrying and storing this device handy. Side guard has been made adjustable, and spindle lock is provided for replacing accessories.

The feature that made this tool unique is its compatibility. This grinder will run on both AC and DC outlets. Besides, the side handle can be mounted on both sides for convenience, whether you are left or right-handed. 

This grinder is equipped with the most powerful motor with the highest amp. But the rotation is low to maintain high torque, which is compulsory to work on materials like wood. With required attachments, this tool works best for wood carving. A spindle-lock system can replace wheels. 

Grinding wheel, flange, wheel guard, lock nut, side handle, spindle washer, lock nut wrench are included with the packaging; almost everything you need to run this machine. This great grinder's price is on the higher side, but the unmatched compatibility and accessories you get make this tool sufficient for most jobs.

  • Rotatable side handle;
  • Suitable for AC and DC;
  • Economic;
  • Accessories included. 

Things We Didn’t Like

  • Not suitable for heavy use;

It comes with a vent to keep the dirt away from users and cooling systems to prevent overheating during long massive duty performance. Changing Sizes is fast and tool-free, so you can switch this device from grinder to cutter.

Angle Grinder

An angle grinder is a kind of handheld power tool that is used for polishing and grinding or abrasive cutting. It is also known as a side grinder or disc grinder. They can be powered with a petrol engine, compressed air, and an electric motor.

The grinder's motor drives a geared head at a right angle on that is placed an abrasive disc or a thinner cut- off disc, either of which you can replace when worn.

In short, angle grinders are the standard equipment for metal fabrication shops & construction sites. They are also used in machine shops with bench grinders & die grinders.

Use of Angle Grinder

Angle grinders are the coolest power tool, as you can use it for many purposes. These power tools are made for grinding metal, sanding, cutting rebar, concrete, and tile, polishing, and sharpening. It is one of the most valuable tools for any garage, workshop, auto repair shop, or DIY hobbyist.

Now I'm going to highlight on some significant use of an angle grinder-

Cleaning

Angle grinders work great for cleaning rust from the tools attached to a wire cup or caked-on cement. It would be best if you made sure that the brush is spinning away from the device; otherwise, you may experience kickback.

Cutting Rebar

If you are going to cut through rebar in concrete, you need to attach a metal cut-off wheel and secure the tool tightly. In this case, using angle grinders are more comfortable and quicker than hacksaws.

Scoring Tile

You can score the middle of a tile by using a diamond blade, and it is much easier than doing with a tile cutter. Outline the hole's size, secure the tile to the workbench using a clamp, and you are ready to cut the hole in the tile.

Sharpening Blades

You can also use your angle grinder to sharpen your other tools. To sharp the blade, you should secure it with a hand clamp or in a vise, position the tool and adjust the blade guard to secure your face and body from the sparks.

Now align the wheel with the blade's angle, start the grinder, and move the wheels over the blade applying light pressure.

Grinding Out the Mortar

With a tuckpointing wheel's help, you can grind out your old and loose mortar without any difficulty.

You need to make two to three 1/2" deep drills to clear the joint and keep it 1/8" away from the brick.

How to Choose

Angle grinders are available in different types, sizes, and styles, and different people have their preferences to serve their purpose. But if you want to get the angle grinder for you, you need to consider the following things before buying.

Type of Grinder

From many types of grinders, one of them is a benchtop grinder. It is secured with a bench for maximum control purposes.

Another type you'll find is the portable grinder; they're available as either angle grinders or die grinders. They're smaller and handier than benchtop grinders.

The third type of grinder is maneuverable and versatile, and they work great for smoothing, sharpening, and cutting.

Finally, you'll find the die grinder, which is designed for one-hand operation. They have small blades and high speed, so you'll work fine in tight spaces.

Size

The size of the grinder is determined by the disc, not by the overall length of the grinder. Big grinders are perfect to complete larger jobs. Usually, professionals go for the big ones as they need to complete their job fast and have to handle many tough situations.

You'll also find small grinders in the market. These grinders can spin at a faster speed and give it the to cut or polish the metal.

So depending on the job you're going to do with the grinder, you should consider the size of the grinder before purchasing is also significant.

Weight

Generally, grinders may weigh differently depending on what size you pick. Some are heavy; some are lightweight. Interestingly, the weight will also vary from one person to another depending on their strength

So it would be best if you went for the one with which you are comfortable working and provide you a secure operating system. This will help you to finish your job perfectly.

Disc Size

Discs of the grinders are available in different sizes. The larger the disc of your grinder, the more powerful the motor of it is.

But the grinders with smaller discs are also great as you'll perform any lower job precisely using them than a larger disc.

Motor Power

It would be best if you considered buying an angle grinder with its power- voltage, wattage, and amp rating.

If you are going to buy the machine for doing household jobs, you can pick the one with a lower rating; they can handle this type of job amazingly.

But if you're going to use the grinder for professional purposes, you should go for the one with heavy-duty. This type of grinder can handle any projects easily.

Speed Rating

You must pay attention to the speed of the grinder you're going to buy. You want to get a powerful one, which will help you to do all your jobs quickly with perfection.

For high-speed grinders, you need to ensure your protection while working with it to avoid any accident risk.

Wheel & Accessories

This one is also another essential feature you should consider while buying the machine. You'll find different types of disc and brush attachment with some grinder. You should check the user guide to ensure that the grinder you're about to buy is right for you and help you perform your desired task correctly.

Handle

If the machine has an adjustable handle, it'll be easy to use for both right and left-handed people. Or the current anti-vibration handle makes the device more comfortable to apply for a long time without any fatigue.

Above all, a machine with a handle that is comfortable to hold gives you the scope to control it and complete your job correctly.

Safety Tips

An angle grinder is the most powerful tool you may own. So you need to be very careful and follow safety tips while using it.

  • Must wear goggles.
  • Always wear ear defenders.
  • Wear hand gloves.
  • Make sure to hold it with a firm grip.
  • Be prepared for the kickback while it starts.
  • Before putting the grinder on the ground, make sure the disc has completely stopped.
  • Never use a cracked disc.
  • Check that the new disc has tightened perfectly.

Conclusion

Still confused! You can go through the list I've provided considering the features, and compare with your needs, you'll be able to pick the right one.

Always try to buy the one that is comfortable to use and apply for different types of work.

With the best disc grinder, you'll handle your own or clients' projects with ease. But you need to ensure your safety first before using it.
