Things to Consider When Buying the Best Angle Grinder
When it comes to current, craftsmen and tool numbers can make a decision between 110 and 230 volts alternating current (AC) while on the other hand, most wattage ranges from 500 to 1500 watts.
From these ratings, you can notice that they highly vary, although the lower the rating in an angle grinder, the insufficient it is for household tasks. An angle grinder with more amperes would be best for heavy-duty professional projects.
It is important to note that the size of the angle grinder’s disc determines the power its motor has. The sizes of the disk can vary immensely with the most used sizes being about 115 millimeters and 230 millimeters.
Most of the time, the craftsman may decide to use a corded grinder with the small discs. The reason behind this is such handheld tools allow for more accuracy on smaller tasks than they would with a standard angle grinder.
The two aspects that go hand in hand with angle grinders, and affect the comfort of using the tool are the discs weight and size. It is good to note that it is more comfortable to use a smaller unit than it is to use a larger unit. This is unless you would want to use the power tool for huge construction on industrial jobs.
The more compact units are easier to hold for a longer time, but grinders with handles that vibrate take operational comfort further.
Wheels and Attachments
The good thing about angle grinder tools is that they are quite versatile. This is because the user can install different wheels, as well as interchange their attachments whenever there is a need to.
There are many different types of wheels and attachment styles in the market. It is therefore quite essential that the craftsman reads the details of the angle grinder before they make a purchase. This ensures that they have chosen the right wheel for the job.
Sharpening tools and other projects that require angle grinders can involve a lot of moving parts and dangerous situations. Safety should be an essential priority for anyone looking to buy one of these tools. Consider the type of safety features your angle grinder provides.
Things like spark guards and eye shields are safety features that can protect you from bodily harm while using your angle grinder. While some angle grinders offer safety in the form of additional attachments, it’s much safer to buy an angle grinder with built-in safety features.
The speed measures how fast your angle grinder rotates. However, too much speed isn't always a good thing. For larger wheels, too much speed can result in the wheel falling off, overheating, or destroying the whole grinder completely because of the disk shattering.
Because of this, we suggest that you respect the maximum speed of your angle grinder relative to your projects. Staying at that speed keeps it from destroying your machine. When shopping for an angle grinder, find its top speed and stay within that range for your device to operate correctly.
Period of Use
When you plan on purchasing an angle grinder, it is important to think about the long-term aspect of it and how long you intend to use it. If you plan on using the grinder occasionally or only when necessary, it is best to get a standard angle grinder. It is used for light-duty tasks.
On the other hand, if you are using the angle grinder for more professional duties that require more complex grinding, it is best to get a more powerful tool.
Most angle grinders on the market offer a slew of different features that aren’t consistent among all the models. These additional features provide a greater experience in some way and how important some of these depend entirely on your personal preferences.
Things like paddle switches, ergonomic handles, anti-vibration features, and adjustable guards all provide an extra level of convenience and functionality to the angle grinder you buy. If these features are important to you, consider purchasing one with more additional features, but be aware that you might pay a premium for them.
Who Needs an Angle Grinder?
To answer this question, it takes you back to the functions of the angle grinder. If you have a task or project that requires sanding, grinding, polishing, cutting or sharpening surfaces, then you definitely qualify for a person who needs an angle grinder.
When it comes to the nitty gritty aspects of having one, it all depends on a variety of factors such as your budget, your expertise and the degree of the task at hand. Different angle grinders can be used for amateurs or professionals while on the other hand, it is dependent on if the task is a DIY project or a large construction project.
Types of Angle Grinders
There are mainly four types of angle grinders mostly used. In addition, they all have different characteristics and uses. It is important to select the correct angle grinder for the right job in order to attain the best results at the end of the day. They include:
Pneumatic Angle Grinders
When it comes to pneumatic angle grinders, they mostly use air pressure supplied by air compressors for successful operation to take place. They are known to be very powerful and cheaper than most types of angle grinders. Nevertheless, when you include the cost of an air compressor, you will notice that the overall price of purchase will be higher.
In the occasion where you already have an air compressor in your garage, then this is the type of angle grinder that suits you. This is because it is friendly to your pockets.
Electric Angle Grinders
Known as the most common and preferred angle grinder, the motor operates by the use of electric power. Because it is quite popular, most manufacturers have made it readily available in the market.
One of the downsides of being powered by electricity is that they can only be used where there is an electric outlet around. It is therefore important to get an electric angle grinder with a substantial cord length. All in all, you can always extend the range using an extension cord.
Gas- Powered angle grinders
With this type of cordless angle grinder, gasoline is used to power the motor, other than commonly used electricity. They are known to be quite powerful and, in this regard, they can be used to perform heavy duty tasks that most angle grinders cannot.
On the flip side, they can be quite heavy and expensive to maintain. You would need to keep refilling the gasoline in order for them to perform their functions optimally. This, in turn, can be quite frustrating in the long run.
Battery-Powered Angle Grinders
As compared to the electric angle grinders, this type needs batteries in order to run. This, therefore, means there is no need for an electric cord. This makes it easy to move them around during operation and when transporting them from one area to another. If it is light in weight, this is an added advantage.
Also, you can use them to reach higher areas without having to worry about having an electrical outlet nearby.
Nonetheless, they run for a limited period of time before the batteries require replacement or recharging. The period of time a battery lasts is dependent on what type of battery is in use and its voltage capacity.
What is mostly preferred are Lithium-ion batteries as compared to Ni-cad batteries because they tend to last longer and can easily be recharged.
As seen it has been, the best angle grinder is one that serves the purpose for which it is made for, is versatile and gets the job done efficiently. After inspecting and introspecting, the angle grinder that gives the highest performance is durable and safe to use is the Makita 9564CV 4-1/2-Inch Angle Grinder.
This is because as compared to the other four, it has an additional feature of the technology that is used to run the tool. This feature is essential as it ensures the craftsman is able to do his/her job without getting tired.
