How to choose the best die grinders
Looking at the array of products we have reviewed, you will see that there are so many big companies that manufacture die grinders. There are several others whose products did not make this list. Each of the products reviewed up there has features that make it unique. You may need a better understanding of the tool before making an informed decision and this is why this section exists.
Electric Vs. Pneumatic
This is one of the biggest difference between die grinders. Neither kind is better than the other in terms of power and performance. The design and quality of the material used determine how well the grinder will perform.
An electric die grinder can only work when there is a source of electricity. Some, however, have the ability to be switched between AC and DC current, allowing you to make use of generators and batteries too. They can be used anywhere you can find electrical current.
Pneumatic die grinders need compressors to work. The compressor must be able to provide enough air pressure to run the tool at the right speed to get the job done. Make sure you have a capable compressor or get ready to buy one if you want a pneumatic die grinder.
Factors to consider when choosing a die grinder
Asides from choosing between electric and pneumatic models, there are other important factors you need to consider when you want to buy a die grinder. These are the factors that will determine the effectiveness of the tool and the value you will derive from it. Here are the most important ones:
Size
What you plan to use the tool for should dictate the size of die grinder you should go for. Think about the scope of projects you are going to handle with the die grinder and buy one with the right size to work on such projects. The size of the area you will use the grinder should be considered too. Smaller die grinders are mostly precious.
Motor Power
This is one of the factors that will determine the performance of any die grinder: the more powerful the motor, the better for you. Depending on the power of the grinder and the speed it offers, the scope of work it can cover may be limited.
Ease of Use
You need a die grinder that is easy to use. Considering that most of the works you will handle with the tool will be intricate and tasking, you need the device, itself, to be easy to use. There are some features that help to make the device great and the design will also influence ease of use.
How It Is Powered
The way a die grinder is powered influences where and how you can use it. While AC powered grinders can be plugged into common household outlets for DIY projects, DC powered units connects directly with generators and other machines used on job sites. AC/DC powered units are great for their versatility but choose according to the nature of the projects you handle.
Other Important Features
There are several other features you have to look out for in a die grinder. Safety features, for instance, are quite necessary for power tools. Other features like variable speed control and ergonomic handles should be considered too. Consider all that a particular device offers and choose correctly.
