Things To Consider Before Buying Angle Grinder…

We have placed the Makita angle grinder at the number 1 position, but that doesn’t mean it is the most suitable grinder for everyone. Each individual has their own needs when choosing an angle grinder. Some want their grinders to be as powerful as possible for doing heavy-duty work, while others want it to be comfortable and ergonomic so that they can work for longer durations. You will also need to look into these factors and decide which grinder best suits you. So we will here discuss some traits of an angle grinder and how do they affect the performance:

1) Size of The Disc

The first and most important thing to look for is the size of the disc, also known as the head or the wheel. Generally, a larger disc implies, a more powerful motor, but that does not mean you always will require a large disc grinder. You will have to decide which size of the disc is optimum for your job. For example, when you need precision in your task,a small pneumatic grinder is what will best suit you. A massive disc grinder will not be ideal for such jobs. Grinder discs come in various sizes, as we have discussed above, ranging from 4.5 inches up to 9 inches.

2) power

An angle grinder can be powered in various ways, as we have discussed at the starting of this article. Each type of grinder has its pros and cons. While the cordless ones (battery and petrol) give you unlimited range, there is always the risk of fuel running out in between your task. The pneumatic and electric ones have a limited range, but since the power source on these is not present inside the tool, they are lighter and thus more comfortable to use, which makes them a consideration when buying an angle grinder if you are always going to have a power source nearby while you work. So, you should ever think of what kind of environment you will be working in and then decide which type will suit you the best.

3) Speed

An angle grinder can rotate anywhere between 5000 to 10,000 rpm. This is what makes them such a versatile tool and also an essential factor while choosing the size of your grinder. Bigger discs operate at a lower speed range (5000 to 6500 rpm), and smaller ones rotate at higher intervals (6500 to 10,000rpm). These are usually the load speeds of the grinders. The no-load speed of an angle grinder can go up to 12,000 rpm. Speeds play an essential role in any task. You cannot use a high-speed grinder for polishing delicate materials else the material can get damaged. Therefore, you should take into consideration the type of material in your task and choose your grinder accordingly.

4) Wattage

The wattage rating of the angle grinder determines its power. The higher the wattage rating of the grinder, the more power it will output, and the easier it will cut and grind the object it comes into contact with. Bigger discs will require more wattage, compared to their smaller counterparts. Also, ensure that the machine has higher amps if you want to do heavy-duty work with it.

5) Safety Features

Safety is of the utmost importance when it comes to using any electric tool. The angle grinder technology has seen a fair amount of advancement to introduce some handy safety features.
• Most of the angle grinders come with a soft start feature that allows you to easily handle the machine while starting it up by avoiding the angle grinder from twisting or wrenching. Also, make sure your angle grinder hasan adjustable side handle and an adjustable guard so you can suitably use your grinder according to the job in hand.
Make sure the grinder you are buying has these safety features before buying.

Types of Angle Grinders

There are several tasks that angle grinders are suitable for, so being aware of the varieties available can be beneficial. Making sure that you have the right kind of angle grinder available for the job in hand will help you to carry out the task in an efficient manner.
The most crucial factor when choosing a suitable angle grinder to work with is the depth or size of the material to be cut or grind and the type of material you will be working with, which, inturn, decides what size and kind of disc you will need.

Most manufacturers make angle grinders and their discs in the following sizes:

• 4.5 inches (115mm)
• 5 inches (125mm)
• 6 inches (150mm)
• 7 inches (180mm)
• 9 inches (230mm)

The most common size of disc used in general, across most areas of use are the 115mm discs. The 115mm is the most common disc size, and you can quickly get one regardless of the type you want it in, be it cutting, smoothing, grinding discs, etc. Due to this fact that 115mm discs are the most common and readily available, they also tend to be the cheapest ones.

In terms of size of the tool, you can get angle grinders in small(4.5 inches), general and light purpose (from 5inches to 7 inches) and large (9 inches) size, with the small sizes being suitable for works such as sharpening blades, cutting reinforcing bars or cleaning rust. When it comes to more substantial or industrial jobs such as cutting large-diameter steel pipes, steel beams, or large paving slabs, the larger 230mm tools are more suited. Mostly, the large ones are the same as the smaller ones; only they are implemented on a larger scale. They also have the same features as their smaller counterparts. Due to their larger size, they are heavier and thus are a little trickier to handle and manage compared to the smaller ones, and although they generally operate at slower speeds, the torque they produce can be substantial.

Smaller angle grinders operate at faster speeds, at above 10,000 rpm, while the larger ones typically operate at 6000 to 6500 rpm. Generally, the faster speeds mean more rapid wearing of the discs. However, due to relatively cheap prices of 115mm discs, it’s still a better option to go for smaller discs rather than a large one if you do not need your angle grinder for daily professional work.

Now that we know a little more about the angle grinders and the sizes they come in, it would now be a good time to look at the various types of grinders you can get based on the way they are powered, and on that basis, it can be divided into four categories, which are as follows:

1) Electric

Electric angle grinders make use of mains power to run the motor. These are very popular in the market and therefore are the most common ones. You can find an electric variant of angle grinder from almost every manufacturer. Since it powered through the mains power supply, it has a cord that is plugged into a socket, therefore giving it a limited range to work. Although, you can extend its range using an extension cord. These type of angle grinders come in a variety of voltages, depending on how powerful it needs to be, and are commonly used for industrial purposes, due to its suitability for heavy-duty jobs. The large size angle grinders are generally electric and more powerful, and thus might require the addition of a second handle to help support the tool while it is in operation. Since they do not carry a power source, they are usually lighter than other options.

2) Battery

An in-built battery powers Battery/Cordless angle grinders. They do not require any kind of cords for operation. Thus they will be easier to move about while in use and when it is to be transported. This advantage, along with the ease with which the power source, i.e., the battery can be replaced and recharged, is what makes it popular among some users. You can always carry an extra battery with you and can work without worrying about running out of power. These mostly come with a rechargeable lithium-ion battery and a charger.

3) Pneumatic

Angle grinders that make use of compressed air form the part of the range of pneumatic tools. These types of angle grinders are powered by compressed air, which is pumped into the devicefrom a compressor. These again have a limited range, like the corded ones. These are only suitable for professionals who make use of other pneumatic tools as well, as you also need to buy an air compressor to power it, and purchasing an air compressor just to power an angle grinder is not a feasible choice. These,too, are less powerful than electric angle grinders but tend to have a longer lifespan.

4) Petrol

As the name suggests, this type of angle grinders is powered by gasoline. These angle grinders often come in the larger sizes, are more massive than the others, and are more suitable for industrial uses as working with them can be a little difficult and require experience. Also, the petrol engine can provide a considerable amount of power for heavy-duty industrial applications. These are also cordless and thus have unlimited range, although you need to make sure you do not run out of fuel supply in the middle of your task.

TYPES OF ANGLE GRINDER DISCS

Angle grinder discs are custom made for the job they were created for. Each disc is labeled either “Stone” or “Metal” and should only be used for working on the labeled material. You can cut stone with metal labeled disc and vice-versa, but that will reduce the lifespan of the disc. Now that we have established that each disc should only be used for what it’s made for, we shall look at the different type of discs available:

Cut off Discs (metal and stone):

These discs are used for cutting. Metal cut off discs for metal and stone cut off discs for stone.

Diamond Cutting Discs:

This type of disc is also used for cutting, but it is diamond tipped on its edges so that it can cut through hard materials like tiles, marble, granite, etc. These also have two types, wet cut, and dry cut. Wet cut discs need to be wet while being used, while dry cut can be used dry.

Abrasive Disc/Pads and Sanding Disc/Pads:

These come as an attachment for a disc. It is a sheet of sandpaper that is attached to a disc through Velcro or some other method, and then the disc is attached to the grinder. These are available in different “grit” counts (grit is the measure of the coarseness of the sheet), from 40 grits to up to 400 grits.

Grinding Discs (metal and stone):

These, as the name suggests, are used for grinding. They also come in metal and stone types and are used for grinding down metal or stone to either shape it or take off lumps or peaks.

Wire Brush and Twist Knot Cups:

Wire brush discs are discs in which groups of wires are twisted up and placed around the perimeter of the cup. The wires in these kinds of discs are quite hard, and the rotating motion of the disc enables you to remove paint and rust easily.

Flap Sanding Discs:

These types of discs can be convenient if what you want to do is some fine grinding. They are primarily used for sanding and cleaning up, but can also be used for some detailed grinding as they are not as hard as the proper grinding disc. They are also available in different grit counts.

Polishing Pads:

These again are an attachment that is attached to a disc, which is, in turn, connected to the angle grinder. They are mainly used for polishing and finishing harder surfaces. Polishers, or mops as they are sometimes referred to, are also available for polishing paintwork and other delicate surfaces. When working on delicate surfaces, it is often advised to use the 230mm disc as it operates at a slower speed.

Also, wear proper protective clothing like gloves and a protective mask to keep yourself safe.

What is the difference between load and a no-load speed of the grinder?

The loading speed of an angle grinder is the speed the disc will rotate with while the tool is being used. The no-load speed is the speed with which the disc will turn while the device is not being used. No-load speeds are usually higher than load speeds.

Should I buy a second-hand angle grinder?

It is usually not advised to buy an electric tool second-hand. It can be dangerous to use a second-hand tool as you don’t know if the condition is as good as the seller told you, which can pose a danger to the operator.

I am sure that by now, you must be feeling more than confident about your angle grinder knowledge. But, this amount of information can be hard to retain. So, to sum it all up, the best grinder in our list was the Makita 9557PBX1 owing to user-friendly designs and features. The most powerful one was the Metabo WEV15-125, and the best overall was the Porter Cable PCE810.
