Buying Guide: How To Choose The Best Angle Grinder?

Corded or cordless

The power source is the first factor when choosing your best angle grinder to use. In other words, you have to determine whether the grinder is a corded or a cordless one.

  • Cordless angle grinders: These grinders provide higher mobility, making them suitable for tight spaces. However, they lack power and functionalities because they depend on the battery capacity.
  • Corded angle grinders: Since corded angle grinders are always connected to a constant power supply, they are more powerful and can handle hard materials. But the pitfall of this grinder type is that you have to use a cord extension when working on a large area. Otherwise, you will be restricted by the length of the electric cord.

Disc size

A grinding/cutting disc (or a wheel) is the main component of an angle grinder, apart from the tool’s body and engine.

The size of a disc indicates its maximum diameter. The larger the attached disc, the more materials and working areas your angle grinder can handle at a time. But these large discs also add up a remarkable weight to the tool itself and make your hand fatigue quickly.

  • For most DIY projects: you should choose compact discs with a diameter of 4 inches, 4.5 inches, or 5 inches. These discs are small enough to get into tight spaces and won’t tire your hands while operating for an extended period.
  • For industrial or professional settings: you should choose a disc size of up to 9 inches to cut very hard or very thick materials or polish larger areas. However, these discs are too bulky and heavy to maneuver in tight spaces.

Disc type

Besides the disc size, you should also choose an appropriate disc type for each specific cutting/grinding task. Below are some most popular angle grinder disc types and their uses:

  • Cut-off discs: These discs can cut through rods, bolts, water pipes, rebar, and other hard materials.
  • Grinding discs: Use a grinding disc to sharpen material’s edges, gardening/farm tools, or dull edges.
  • Diamond discs: The diamond-tipped teeth of these discs are excellent to handle granite, porcelain tile, masonry, concrete, etc. They can be used as dry or wet cutting.
  • Sanding discs: These discs are excellent alternatives to sanding pads. They can remove paint on surfaces with minimal damages and maximum efficiency. You can use these discs for coarse sanding or fine sanding, depending on the abrasive level of the discs.
  • Aluminum oxide discs: These discs are commonly used in woodworking to handle softwood or hardwood surfaces.
  • Wire brushes: Like sanding discs, these grinder attachments can be used to remove rust or flaky paint off a metal surface.
  • Silicon carbide discs: These discs are used to shape materials or grind down excess materials (like welding). You can also utilize these discs in knife making.

Different Types of Angle Grinder Disc

Maximum working speed

The operating speed of an angle grinder’s motor is measured in RPM (revolutions per minute or rotations per minute). This speed is often marked as “no-load speed,” or the speed when the tool doesn’t cut or grind anything. Hence, this speed can be lower when being on the job.

The speed of an angle grinder varies by its size. Most compact models have a no-load rate from 5,000 to 10,000 RPM. Some robust premium models can be up to 12,000 RPM.

A grinder with a higher RPM can cut or grind materials easier and quicker, but it can also become hotter when running at high speeds.

For the safety of you and your grinder, you should choose the appropriate disc for the tasks. Also, don’t exceed the maximum support disc speed.

Power output

The power output of an angle grinder determines how quickly and efficiently you can get your jobs done, and it is measured in Volt (V) or Amperage (amp).

On a cordless grinder, the power output is shown as Volt. Grinders with a Voltage of 18V and 20V are the two most well-known product groups, thanks to their affordability and functionality. Besides, there are minor models with the Voltage ranging from 7.5V to 24V.

The Voltage on a corded grinder is only to indicate the power outlet that it can use (for instance, 120V or 220V outlet). Its power output is shown as Amperage, with the most popular range of 5-15amps.

Larger grinders or larger discs require larger output. For example, an angle grinder running on a 7-inch or 9-inch disc requires more power output than a grinder with a 4.5-inch disc.

The power output of some grinder models can also be demonstrated in horsepower. For instance, 1,000W can be translated to 1.34 HP.

Durability

Power tools like angle grinders are meant to tackle hardcore tasks day by day, so you should choose a sturdy model made of durable materials or have extreme internal and external hardiness.

You should pick up a grinder from a well-known brand with a good reputation, or one that comes with an extended warranty (for example, 3-year warranty) or money-back guarantee.

Ergonomic design

The design of an angle grinder affects your performance and your safety. Your best angle grinder is the one that you find most relaxed when handling it.

Cordless grinders are more comfortable than corded ones because they are lighter and not restricted by an electric cord or cord extension.

Besides, some other highlights determine the ergonomics of a grinder, like a non-slip handle, removable/adjustable side handlers, an adjustable safety guard, a slim body, etc.

Angle grinder handle

Safety features

Angle grinders are versatile tools for many jobs and materials, but they can also be dangerous even for experienced users. To enhance their safety, some manufacturers include safety features, like soft-start technology, anti-kickback, paddled switches, and so on.

Safety guard

This safety guard covers half of the disc, protecting your hands and wrists from hot metal sparks and flying debris. This safety component does not only appear on the best angle grinder models but is considered a must-have for all grinders on the market.

In other words, you should always choose an angle grinder with a safety guard installed.

There are two types of grinder guards: a fixed guard and an adjustable guard.

  • Fixed guard: This guard is robust and can’t fall off like an adjustable guard. But some users might find the guard’s position weird.
  • Adjustable guard: This guard type is more popular since it is usable for left-handed and right-handed users. You can also modify the guard’s position to be most comfortable for yourself. But you should check if the guard is properly installed or not, or the guard can fall off while the tool is running at high speeds.

Angle grinder guard

Dust management

An angle grinder generates a lot of dust while working. When being left uncared, this dust can cause accidents to you, your tool, and people around you or respiratory hazards in the long run.

Apart from wearing a proper safety mask, you should pick up a tool with a dust management system. For example, some grinders have a dust eject system to prevent dust and small particles from flying towards you or reaching the motor.

angle grinder Cup Wheel Dust Guard

Soft start technology

Since angle grinders are powerful and run fast on big wheels, they can slightly recoil at startup. At times, the tool can jump into your hands and wrists and cause severe injuries.

Therefore, the soft-start technology is integrated into some grinder models to gradually increase the tool’s power output until reaching your desired speed, keeping you safe from those unwanted accidents.

How To Change The Blade On An Angle Grinder?

You can change the blade on an angle grinder with the following simple 5 steps:

  • Step 1: Turn the grinder off, unplug it, or remove the battery.
  • Step 2: Remove the safety guard using a screwdriver.
  • Step 3: Press and hold the blade’s lock button, then turn the angle grinder upside down. Check if the wheel is locked or not by spinning it. If it turns, you need to press and hold the lock button once more.
  • Step 4: Rotate the arbor nut counterclockwise with the provided wrench. If you don’t have this wrench, you can use the Vise-Grips.
  • Step 5: Replace the current blade with a new one into position. Reinsert and tighten the arbor nut enough to keep it in place.

How To Safely Use Angle Grinders?

To use angle grinders, you should follow these safety tips:

Wear proper protection gear

Ensure to wear proper Personal Protective Equipment (PPE) before handing an angle grinder. A full PPE includes long sleeves, gloves, hearing protection, full-face shield.

Wear Safety Equipment

Place the grinder properly

Each task requires different angles. When placing your grinder at the right angle, you can prevent the flying sparks and debris from flying towards you. Thus, you will lessen possible injuries for you, damages to your safety clothes, or fires on your worksites.

  • For cutting: Place the cutting disc straight and try not to bend it in any direction. The safety guard should be on the top of the tool, between the disc and your face, to protect you from hot sparks and debris. You should also wear a full-face shield when handling cutting jobs.
  • For light grinding and sanding: Place the grinder at a 5-10o angle with minimal pressure to not damage the working surface.
  • For general grinding: Maintain an angle of 20-30o angle between the grinder and the working surface, with the back of guard towards your body. Let the disc do its work with a little applied pressure to get the job done smoothly and efficiently.

Use suitable accessories

You should use accessories (discs/cups/wire brushes) that are compatible with your angle grinder. Please check the specifications of the grinder and the accessory to know this device-accessory compatibility.

That says the maximum RPM of the accessory should be equal to or exceed the maximum RPM of the grinder.

Angle Grinder Attachments

Other tips

  • Allow the grinder to reach its full speed before applying it to the surface for consistent performance.
  • Keep the tool grinding and sanding consistently to avoid gouges and to have smooth results.
  • Unplug the grinder before placing it down to avoid accidents and damages to the surfaces. Plus, you should also choose a grinder with a mechanical or electric braking system.
  • Choose an angle grinder with a paddled switch to stop the tool instantly when you lose control of the tool. Alternatively, a “zero-voltage” feature is an excellent safety feature to avoid kickbacks.
  • Never remove the safety guard when working with a fast, powerful tool like angle grinders since it can cause severe injuries for you.
