Buyer’s Guide

It would help if you made proper considerations before buying the best angle grinder for 2021 that suits all your project needs. So here are a few features of angle grinders that you must keep in mind.

#1 Power source

The type of power source divides the angle grinders into three categories: corded, cordless, and pneumatic. Most of the angle grinders manufactured nowadays are battery-powered or cordless. Corded and air compressed options are fewer but still available in the market and therefore needs to be considered. So power source is a salient feature of angle grinders.

Battery-powered or cordless angle grinder-

A cordless angle grinder uses lithium-ion batteries and brushless electric motors to operate. These new technologies play a crucial role in increasing the grinder’s lifetime, i.e., it lasts longer after a recharge. The grinder’s charging can take a few hours, which can halt and hamper your work session. So if you are working outside your workshop, you must always carry an extra set of batteries. The latest technology cordless angle grinders have a 6 Ah battery charged in only 30 minutes.

A cordless one weighs around 2-3 pounds more than corded grinders but serves its purpose correctly. You can use them while doing scaffold-based grinding tasks as it reduces the chance of tripping over trailing wires. Go for models that can accommodate high-powered batteries.

Corded angle grinder-

Corded angle grinders are lightweight and cheaper than cordless models and provide a high power consistent output. The grinder can run indefinitely without the need to recharge it. All you have to do is plug the grinder into a standard power outlet. But, this can limit your work area as the length of the cord is limited. You also have to take care of not grinding through the power cord.

Use models with small discs if you are doing minor cutting jobs. It is necessary to also consider the level of vibration of the grinder before purchasing it.

Pneumatic angle grinders-

The pneumatic angle grinders are powered by air pressure, taking technology-powered tools to a whole new level. Professionals mostly use them to perfect their craft. It is an advanced version of the corded model where the grinder needs to be plugged into an air compressor. It is also the lightest and cheapest option, as electric motors or batteries do not power it. But you should check the model thoroughly before purchasing it.

It is durable and also has excellent performance stats. So use the pneumatic angle grinder for high precision jobs and shaping metal pieces. Some models also come with throttle levers, which add to the performance. It makes feather edging and speed grinding perfect and more effortless.

Petrol powered angle grinders:

As the name suggests, these grinders are powered using petrol and alternative to the battery-powered cordless variety. Industries use these models as they are large. You need to check if you have enough fuel to complete your job and make sure that there is no fuel leakage.

#2 Disc types:

Angle grinders have different types of discs that serve other purposes. Your kind of job decides the type of wheel or disc you will need. They can be cutting discs, wire discs, grinding discs, and flap discs.

  • We use Cutting discs to cut metals and are very thin compared to the other available disc choices.
  • We use wire discs to clean and polish metal surfaces that are not decayed. Paint stripping discs play the role of removing the rust and old paint from metal surfaces.
  • Grinding discs help smooth surfaces as they are thicker than 5mm. We also use it to remove slag.
  • Flap discs help smoothen surfaces as they are covered with sandpaper.

#3 Disc Size:

Disc size of the angle grinder depends on your type of work. It also determines the power and capacity of the tool. Large-sized disks are mostly used to do a large quantity of work and are also very powerful. It gives an excellent finish in less amount of time. Use smaller discs for jobs that need precision. It can also work in small spaces and tight angles efficiently.

Disc size can vary from 4 to 9 inches. For your DIY projects, use a disc size of 4-4.5 inches as they are relatively easy to use. They can be used on different surfaces and are exceptionally lightweight. Use a disc size of 9 inches for industrial purposes.

#4 Disc speed in RPM:

Disc speed also plays a vital role in grinder choice. The speed and performance of the grinder are directly proportional. Most grinders have a speed of 5000-10,000 RPM (revolutions per minute). The more incredible the speed, the better is the result.

Choose angle grinders in which you can change the speed according to your requirement. It is suggested because you need the experience to control and operate high-speed grinders properly. If your grinder does not come with variable speed settings, choose grinders with a speed that you can manage easily.

RPM is also known as “no load speed.” It means the speed the grinder has when there are no discs installed in it. Higher rpm comes with larger disc sizes. So even if two angle grinders have the same amp value (input power), choose the higher rpm machine.

#5 Motor power

Wattage (Watts, W) measures an angle grinder’s output power; however, the input power varies depending on the model. In cordless models, the input power is rated in volts (V); in corded models, it is in amps (A); and pneumatic models measure input power in cubic feet per minute(CFM). Pneumatic models also use pounds per square inch (PSI) to measure operating pressure.

A higher wattage power grinder does not ensure heavy usage of the tool or its ability to handle excessive friction. But the higher input power (higher amperage) helps in performing large-scale projects. You can start with 7-8 amps and then move up to 9-10 amps as you gain experience. Corded angle grinders can have voltage as high as 110 V or 240 V., But the rechargeable cordless models only have 18V, which is comparatively very low.

If you are doing heavy projects, go for angle grinders with high wattage and large discs. If you want to select between two grinders that provide the same rpm, compare their amp ratings. Select one with the higher amp rating as it will give more torque.

#6 Weight

The weight of the angle grinder also decides what use the product will be. Weekend projects do not require heavy and bulky tools, nor are they necessary. Use a lighter angle grinder for such projects, as they are not made for years of use. Or you can go for average weighted machines, between 3-10 pounds.

#7 Loud Noise

Angle grinders add to the noise pollution of the environment. But there is no way to prevent it as any machine will make noise while cutting and grinding. So wear ear defenders to protect your ears and work in secluded areas not to disturb others.

#8 Durability

Look for angle grinders that come with internal as well as external durability. They can also have a 3-year warranty as it will be a bonus. Angle grinders must have an excellent working life to handle challenging projects.

#9 Brushless grinders

Buy a grinder with a brushless motor as they have fewer parts that can get rusted over time. It may be expensive, but it is a value-for-money product.

#10 Safety features

Welding can be hazardous, and you need to take some precautions before proceeding with it. Heavy angle grinders can increase the risk of injuries. So you must wear safety goggles and gloves while using these instruments. One can also purchase additional features like disc brakes, safety guards, locking systems, and switches along with the grinder.

  • Disc brake: A disc will continue to spin unless it is stopped by gravity if no disc brake is attached to it. A trigger/ paddle controls the disc brake. You can stop the disc when you complete your work and prevent injuries.
  • Adjustable disc guard– This particular can be adjusted to protect you from flying debris and sparks from the project you are working on.
  • Dust sealed– These are special dust protection guards that prevent dust from entering nearby tools and working parts. Dust can destroy inner electrical components and the work of a machine.
  • Spindle lock: The lock tightens the spindle and stops it from turning. It helps you to change the disc without hurting yourself.
  • Handguard: They protect our hands from sparks and fragments that emit from our project.
  • Movable side handles- As the name suggests, you can move the handle to suit our project needs to different positions. You can also operate it with your left or right hand.
  • Anti-vibration handle: This feature of the grinder is unique as it makes it possible for the user to use the grinder handle for long periods without getting tired. It also increases the control over the project.
  • Vacuum attachment: The grinders can be attached to a vacuum to bring down the amount of dust generated.
  • Type of switch– Grinders also come with various kinds of switches like a paddle and slide-up switches. Slide-up controls make it easier to turn off the tool.

#11 More disc attachments

  • Cutoff Disc: It cuts hard metal objects like rods, rebars, and metal pipes.
  • Grinding discs: It is used to sharpen edges of tools faster, like that of gardening equipment.
  • Silicon Carbide Discs: It is a multi-purpose disc with endless uses. It can grind metals, sharpen tools, clean sheet metals, and shape the metal according to our desired shape.
  • Wire brush wheels: These remove rust and paint from metals that have already been used.
  • Sanding pads: It also removes old paint and sands it to prepare the surface for further steps.
  • Diamond cutting blades: They are useful in both dry and wet welding as they can cut through concrete, tiles, or even granite.
  • Aluminium oxide wheels: It is mostly used while working with wood and cut particle boards.

#12 Price and warranty

The price of any machine is significant as a good-quality angle grinder can make or break your project. So select the best angle grinder in your price range. Buy products that come with at least a year of warranty to act as a security.

Types of angle grinders

Before investing in the best angle grinder, you need to understand its different types and their purposes. The three main types are cordless angle grinders, corded angle grinders, and pneumatic angle grinders. Apart from these, we also have the Variable Speed angle grinder and Straight angle grinders.

Variable speed angle grinder

The discs present in this angle grinder have different speed settings for various applications. A high RPM assists in high-precision work by making it faster and easier. These grinders can also have paddle switches to give more control to the user.

Straight angle grinder

The specialty of this grinder is the 90- degree angle of the wheel. It helps to grind out inner and outer pieces effectively, as it has various grinding stones attached to it. The unique disc angle increases the functionality of the straight angle grinders’ many-fold.

Uses of Angle Grinders

We use angle grinders for four main reasons:

  • Cutting– Angle grinders can cut through strong materials like metal and ceramics, so they are preferred over saws. You don’t need to take the material to be cut to the tool. You can cut it in its original place. So angle grinders provide excellent maneuverability.
  • Grinding– it is the primary use of the tool. An angle grinder can grind through masonry and also smooth materials quickly.
  • Polishing: Angle grinders use special polishing discs to polish surfaces, which is aided by the device’s high RPM.
  • Sanding: An angle grinder can smoothen surfaces using sanding discs, providing an alternative for a traditional sander.

Angle grinders remove dust from a material, sharpening of blades of tools, material finishing, and application of matte finishing. They are also used in emergency rescue as they can cut through various types of materials.

Angle grinders are an essential part of wood-working and metal-working. They can extra cut-off pieces of the metal and act as a sander to smooth it. Angle grinders have applications mostly in industries like engineering, construction, automobile tools, and many more.

Operational Tips:

Assemble the angle grinder according to the steps mentioned in the instruction manual. Pay attention to the angle of the handle, electricity flow, etc., while assembling. Some extra tips that you should keep in mind are:

Protect yourself

We advise you to wear industrial safety tools like masks or eye gear with gloves while operating the device. Proper care is required to use a power tool safely. On the usage of angle grinders, debris and sparks fly from it, entering your eyes and damaging it. So safety of your personnel is a must.

Prepare the work area

Keep your work area clean and uncluttered, and remove unnecessary objects from it. Corded angle grinders can also increase the chances of tripping, so keep that in mind while moving around. People in your surrounding area must maintain a safe distance from your workplace. Your indoor workspace must also have proper ventilation. Cutting and sanding using an angle grinder produce a lot of heat due to friction, which can become suffocating without ventilation.

Mark the cutline

To make things more straightforward for yourself:

  1. Mark the area you want to cut before actually using the angle grinder.
  2. Make a small slit with a hammer to keep the spot working with concrete.
  3. Place your blade correctly at the desired location and then power on the machine, which will reduce the chance of errors.

Check your grip

Angle grinders come with two grips that have different uses. So check which grip you want to use before powering the grinder. Angle grinders feel heavier due to the handle’s vibrations, so have a firm grip and test it out beforehand. Apply little pressure where you want to cut and check the grip ahead.

Use the correct grinding disc

You should use the correct type of disc along with the right size while working. It will depend on the material you are working on. It would be best if you did not use metal discs to cut ceramics or stone, as it will wear down the disc and destroy the material.

Use the grinder correctly

Use the grinder with the safety guard. Please do not remove it to make your job easier. Safety guards must always be kept in place. Hold the angle grinder with two hands to avoid twisting it. Also, inspect it properly before usage and replace parts that may seem damaged or rusty.
