What Is an Angle Grinder?

An angle grinder is a simple tool which uses a power source, commonly an electric motor which operates a set of gears that rotates the head. The head is placed at an angle of 90° to the motor and a wheel is attached to the head by a retaining ring. A safety guard covers the rear portion of the disk, which can be rotated to change the path of the debris or sparks.

The angle grinder is usually operated by gripping the main body and a trigger or a switch delivers power to the motor to rotate the wheel. Usually, the angle grinder is also equipped with a side handle that can be mounted on the right or the left, which offers greater control. The trigger has a lock button to prevent accidental starting of the grinder. The spindle lock also allows you to change the wheels of the angle grinder without any movement.

Usually, compressed air is used as a power source in metalworking shops and auto body units. However, the ones used at home are usually the electric type, which may be wired or cordless. Angle grinders are extremely versatile tools and you can attach different types of wheels for various applications and you can attach other gadgets too.

Types of Angle Grinders

There are several different types of angle grinders that are suitable for different applications. Being aware of the different kinds of grinders can help you to make the choice of the right tool for all your jobs and help you decide on the one that will work best for you.

Electric Angle Grinder

This is the most common type of angle grinder available and the motor makes use of electric power supply to work. Electric angle grinders come with a cord that is plugged into the power outlet. This, however, restricts the range of the angle grinder, but to extend the reach of the grinder, you can make use of an extension cord.

Electric angle grinders are available in different range of voltages and depending on how powerful you require the angle grinder to be, you can choose the right one for your applications. Electric models are usually used on construction sites as they are more suited for heavy-duty jobs.

Typically, larger and more powerful angle grinders are electric powered and these require a second handle for additional support when the grinder is in operation.

Battery-Operated Angle Grinder

Battery-operated angle grinders are cordless, as they are powered by batteries and are more convenient than the corded varieties. These cordless angle grinders are easy to use and you can move around with them and also transport them easily without being hampered by the cord. With a cordless angle grinder, you don’t have to worry about being near a power outlet and you can also use these in remote locations where there is no power.

Battery-operated angle grinders are very popular as you can recharge the batteries or replace them without any hassle. A good idea is to keep two batteries at hand so that you can make use of one, while the other is being charged. Most of the angle grinders make use of lithium-ion batteries, as they are lightweight and can also be recharged. Some angle grinder models come along with a charger too.

Pneumatic Angle Grinder

Pneumatic angle grinders use compressed air to work. Although pneumatic angle grinders are smaller in size, they produce quite a lot of power. You can attach an adjustable handle and also use a safety guard with pneumatic angle grinders too just like other grinders. However, the only drawback of the pneumatic models compared to the larger angle grinders is that these make use of smaller discs, which work with more RPMs (revolutions per minute), that results in the disc wearing out more quickly.

Gasoline Angle Grinder

These models of angle grinders are powered by gasoline and are an alternative to cordless angle grinders. Gas-powered angle grinders are larger in size and are usually used for industrial applications. However, you must ensure that you use the right kind of gas for the tool and you must have sufficient supply of gas in order to complete the work without interruptions. Also, with gas-powered angle grinders, you need to take precautions while using the tool so that there are no leakages.

Types of Discs

Angle grinders are essentially used for grinding parts or surfaces and they can also be utilized for cutting and polishing jobs. As we know, there are different kinds of angle grinders that exist – from small hand-held varieties for DIY and home applications to large angle grinders that are suitable for commercial applications. There are different angle grinders and discs for different purposes. For instance, the grinder disc used for cutting glass is very different from that which is used for removing rust or polishing.

So, it is essential that you determine the type of angle grinder disc required for your particular job. However, before investing in a grinder disc, it is a good idea to keep a few things in mind like power, size, speed and safety. Here, we will be looking at a few types of grinder angle discs that are suited for specific jobs.

Grit Discs

These are the most inexpensive discs available. Grit discs are usually around 6 mm and are much thinner when compared to the other types of grinding discs. They are usually used to cut and grind materials like metal and stone. Grit discs can cut at a much quicker speed and since a grit disc angle grinder is not very heavy, it can be held very comfortably and used even when standing on a ladder.

Diamond Discs

These discs are quite superior compared to grit discs and are also used for cutting and grinding. However, diamond discs cut more quickly than grit discs. Diamond discs are also more long-lasting than grit discs and are safer to use. Diamond discs have become more affordable in the recent years which makes them a viable option.

Wood Discs

Wood discs are usually used to cut wood. However, buying a disc that just cuts only wood may be an extravagance, so you should ideally look for a disc that can also cut steel so that you can use it to cut a nail embedded in the wood.

Wire Wheel Discs

The wire wheel disc is used for removing paint and rust from any surface and also for polishing. So, if you need to remove any paint or metallic rust from any surface, the wire wheel disc is the best tool for this. However, you must ensure that the surface or object on which you’re using the wire wheel disc is sturdy enough and the wire wheel will not damage or break it. There are many different kinds of wire wheel discs available and the most effective type is the twisted wire wheel disc, while the cup brush type of disc is the least effective.

Uses of Angle Grinders

Angle grinders can be used for several different kinds of applications. The most common use of angle grinders is for sanding or grinding excess metal, mortar or stone. Typically, angle grinders are used by construction workers for working with various metals, making cuts and notches, shaping stone and other materials, etc. However, the use of angle grinders goes much beyond just these uses and can be used for other applications such as:

Sharpening Blades

You can use angle grinders for tasks beyond cutting materials and polishing and they can be used to sharpen the various tools around your home and garden such as knives, axes, garden shears, shovels, ice scrapers, hoes, lawn mower blades, etc. However, the one thing you must take care is that when you are sharpening these implements, before attempting to sharpen them, you should clamp the blades firmly to the work table. Not securing these sharp tools can be quite dangerous.

Removing Mortar

The angle grinder can be used to remove any old or loose mortar without causing any damage to the flanking bricks. Using an angle grinder with a diamond tuckpointing disc makes this work very easy and you can avoid the hard labor that you need to do when using a hammer and chisel.

Carpentry

If you’re taking up a carpentry project like building a new bedroom in your home, a deck or even cabinets, angle grinders are excellent tools for such projects. These grinders can quickly and efficiently remove unnecessary materials and are excellent tools for smoothing the rough cuts and for leveling joints, etc. You can use an angle grinder to make bevels or deep grooves very quickly and they are perfect if you want to build accented panels for doors, sleek wooden furniture, etc.

Painting

Before you paint any surface, it needs to be cleaned and prepared properly. This calls for removing any old coat of paint and smoothing the surface by removing any burrs or swells. The correct angle grinder can help you handle these tasks effortlessly and efficiently since the angle grinder peels away really old layers of paint easily and efficiently. You can make use of a grinder for quicker completion of your work compared to using tools like sandpaper, which requires more effort and is very time-consuming too.

Flooring

Angle grinders are excellent tools for flooring projects. If you want to smooth out raised nail heads, buckled joints or any parts jutting out from the subflooring, making use of an angle grinder makes the job very easy. Using an angle grinder with a proper cutting wheel can make the cutting of tile and wood very easy when you’re laying a wooden or tiled floor. You can also use the angle grinder to grind down the uneven or excess grouting.

Plumbing

An angle grinder can be used for plumbing jobs and allows you to cut through old pipes for any demolition work; you can also use the grinder to precision cut new pipes. And, if the cutting is uneven, the grinder can be used to smoothen the uneven surface of the pipe. Plumbers also make use of angle grinders to cut through wall and floor pipes to access the pipes underneath.

Angle grinders can be used for several kinds of home improvement jobs apart from just these applications. If you have any job that involves metal, wood, hard plastic or stone that requires cutting, cleaning, polishing, buffing, sanding, sharpening or smoothening, an angle grinder comes very handy.

Factors to Consider When Buying an Angle Grinder

There are several varieties, models and brands of angle grinders available in the market today. Although you may be very tempted to buy a low cost, inexpensive model, it is a good idea to invest in buying a good quality angle grinder that offers power, performance and safety, which may be a little more expensive. However, the higher cost is worth the long-term investment and it is especially useful if you are a frequent user. However, if you use the angle grinder occasionally for small projects, then you could go in for an inexpensive model.

A single angle grinder may not be suitable for all applications. So, it is very important that you determine your requirements and what you will be using the angle grinder for before buying one. The 2 major factors to consider when buying an angle grinder are the disc size and the motor power. The other factors that must also be considered are RPM (revolutions per minute), power source and arbor size.

Disc Size

Typically, the larger the angle grinder’s disc, the greater the power of the motor. There are different sizes of angle grinder discs available, of which, 4.5 inches and 9 inches are the most popularly used. In some cases where pneumatic angle grinders are used, they have smaller disc sizes, which allow more precision and accuracy on smaller tasks than a standard sized angle grinder.

Motor Power

Different angle grinders can have varied amp, wattage and voltage ratings. You have the option of 110 and 230 Volts, wattage ranging between 500-2,500 watts and 4-15 amps and these figures directly have a bearing on the motor power of the tool. While for household use, an angle grinder with a lower rating is enough, for professional heavy-duty jobs, you require an angle grinder with more amperage.

Speed Rating

A handheld angle grinder is quite powerful and when in operation, the disc produces around 5,000-10,000 RPM. This means that you can perform many types of tasks like grinding, cutting, sanding etc. at very high speeds, but at the same time, if not handled correctly, this high speed can also cause injury or damage to property.

Comfort of Use

The size and the weight of the angle grinder affect the comfort of handling the tool. For the purpose of small DIY jobs or use at home, small angle grinders would suffice, as they are more comfortable and easy to handle, whereas, for heavy-duty industrial and construction jobs, you may have to buy a larger and more powerful angle grinder. Small, compact angle grinders are lightweight and they are easy to hold and work with for prolonged periods of time. An angle grinder equipped with an anti-vibration handle can take the comfort factor a step further.

Dust Management

The angle grinder should have a good mechanism to manage the dust and debris. A good dust management system in the angle grinder enables you to work with the tool very easily and this also ensures the longevity of the tool.

Safety Features

Some of the best angle grinders have safety features such as a tool-free wheel guard that allows you to reposition the guard safely and they also have a safety slip clutch, among other safety features.

Wheels and Accessories

You can change the discs of the angle grinder and use them for various applications. You can also use the angle grinder with various accessories and wheels as required. There are so many brush and wheel attachments that are available that you should first understand and decide the ones that you will be using the most, before buying the tool that is right for you.

Some Safety Tips for Angle Grinder Usage

If not handled properly, even the best of angle grinders can cause injuries. Here are some tips that can help you stay safe when using an angle grinder:

• Always wear safety gloves and a face shield when working with an angle grinder.
• Ensure that the attachment or disc that you’re using with the angle grinder is appropriate for the particular job and the material you’re working with.
• Avoid using damaged or worn out attachments.
• Never use the cutting disc without checking it first for any cracks, wear or damage. Avoid using it if there is any damage or wear.
• Avoid using the angle grinder without attaching the guard or if the guard is attached in the wrong place.
• Before working with the angle grinder, check the electrical connections, if you’re using an electric tool.
• It is a good idea to use an angle grinder that has safety features such as a braking system and safety clutch with anti-kickback, etc.

Maintenance Tips for Your Angle Grinder

With proper maintenance, your angle grinder can last you for a very long time. Here are some tips for the maintenance of your angle grinder:

• After every use, wipe the angle grinder clean with a damp cloth, especially the external casing.
• Wipe any dust and debris build-up around the switch of the tool regularly.
• Once in a while, check the gearbox for an accumulation of any concrete or metal dust and clean it.
• You can make use of an air compressor and blow some air into the air vents of the angle grinder to remove any dust particles that may have clogged the cooling fan.

 

An angle grinder is a great tool to have in your toolkit if you are an avid DIYer or a professional. It is a fantastic versatile tool with many uses and can be used for cutting, polishing, grinding and sharpening jobs. Angle grinders are available in varied sizes and different disc speeds, wheel diameters, wattage, etc. So, when you are buying an angle grinder, you must evaluate the kind of projects that you will be doing and buy a grinder that meets the specific requirements of the jobs you will be carrying out.
