Things to Consider When Purchasing the Best Die Grinder
Before purchasing a die grinder, it is of utmost importance to take a few aspects into consideration. Price is not the only factor to think about. Once you know what kind of job or purpose you need for a die grinder, then you can proceed to look into the following aspects before purchasing.
The size of the die grinder is dependent on the job you would like to do. If you are polishing a surface or working on a small project, you do not need a large size. However, if you are working in an industry or a construction site, using a ¼ inch die will be quite hectic.
The powerful the motor is, the higher the performance of the die grinder will be. This is one of the most important aspects to consider because it controls the speed of the grinding wheel. A motor with a horsepower of 0.25 is good enough for your needs.
Right Angle or Straight Head
Whether you decide to purchase a right-angled or a straight head grinder, it is all a matter of preference. Nonetheless, right-angled die grinders are more popular because of their comfortability and ability to reach tight spots. Also, such die grinders can easily be mounted with a grinding wheel.
When grinding on surfaces such as wood boards or plastic tubing, it is best to use a lower speed. Most people use the highest speeds, but this only applies for harder surfaces like metal. The highest speed for the best performance while keeping vibrations down is advised to be 20,000rpm. (Revolutions per Minute)
The three major power sources for die grinders are corded-electric, cordless and pneumatic. To make an informed decision on which one to buy depends on certain variables. The thing here is to carefully analyze what works for you.
If you plan to purchase an air compressor or you already have one in your possession, the best thing to do is to have a pneumatic die grinder. This will go a long way. The thing with a cordless model is that the batteries do not last long per charge.
This means that you always need to keep halting your job in order to charge the tool, then continue. This can be quite frustrating.On the other hand, with corded-electric models, you have to take into consideration comfortability and maneuverability.
This can be hard to come by and if you get one, it may not be budget friendly.
PSI and CFM Ratings
If you lean more towards cordless and corded-electric, then ignore this aspect. Nevertheless, if you are interested in a pneumatic die grinder, ensure that your air compressor can provide enough CFM (cubic feet per minute) at the right PSI (pounds per square inch).
The amount of air forced through the tool is dependent on the speed and power behind the pneumatic air grinder. If your air compressor can work at the minimum volume and pressure, then you are good to go.
What is a Die Grinder?
In simple terms, this is a handheld power tool that is used for polishing, honing, sanding, grinding or machining materials. These materials can range from wood to plastic, as well as metal. With some die grinders, you are required to change the grinding wheels and use the wheel that is catered to the specific surface.
The main purpose of a die grinder is to grind, polish or sand areas that are too tight or far to reach with other equipment such as the angle grinder. This powerful tool normally comes with a spindle spun either by air or electric power.
What this spindle does is that it holds a collet for abrasive and polishing attachments, cutting wheels, bits and among others. There are two major types of die grinders: pneumatic and electrical. For household use, it is advisable to go for an electric die grinder.
On the other hand, a pneumatic die grinder is best performance-wise. They can be used for a longer period of time, while still maintaining the low heat. This means it can be based used in an industrial setting.
From the information above, it is evident to see that the best die grinder is one that fulfills its purpose and the craftsman’s’ needs efficiently. After carefully inspecting and introspecting, it is safe to say that the best die grinder is the Makita GD0601 1/4-Inch Die Grinder.
