Things to Consider When Choosing the Best Die Grinder 

Once you establish the nature of your job, it is important you consider a few aspects before you purchase your utmost grinder. Although the price will play a significant role when making the decision, there are other things that you need to consider. These are;

i. Power Source

When it comes to power sources, die grinder are available in corded electric, cordless and pneumatic variants. Choosing one version over other is determined by certain variables, but the most important thing is evaluating what works for you.

A pneumatic die grinder will go a long way if you have an air compressor of if you intend to buy one. Cordless models, on the other hand, are powered by batteries that need to be charged before and while working depending on task requirements. This will come in handy when you do not need to use the grinder continually as the batteries do not last long per change.

Corded-electric models tend to be more expensive than the other versions due to their ease of use. Also, they can be used for long hours as they do not depend on the availability of compressed air or a charged battery. However, you will need to factor in maneuverability when choosing this model.

ii. Ease of Use

You may need to pay attention to the ease of use that comes with different models of die grinders. For example, you may want to consider the location of the exhaust vents to ensure that they do not face your body. A forward-facing vent, on the other hand, helps to keep the working surface clean but it can displace shavings or oil on the working which could potentially create a mess. . 

Other attributes include safety features that will prevent accidental start-ups, especially when unauthorized people or children gain access to your tool. Some users, however, prefer a simple on/off switch. 

You may also want to consider how much a grinder vibrates during operation. Some models tend to vibrate more while working while others don’t. This can be a bother to some people, especially during long-duration work. 

The weight of each particular model should also be factored in since doing a perfect job often requires time. This means you’re going to hold and move around with the die grinder the entire time. A lighter grinder is more comfortable to walk around with thus reducing operator fatigue.

iii. Speed Control

Although most operators use their die grinders at full speed, die grinders are designed to allow for speed control depending on the nature of the working surface. You can use a lower speed for soft surfaces such as wood boards. Harder surfaces require higher speed ratings, but you want to keep within the recommended rate of 20,000 rpm.

iv. CFM and PSI Ratings

This aspect is vital if you are into pneumatic die grinders. You should ensure that your air compressor can provide enough CFM at the correct psi, i.e., appropriate pressure level. The amount of air drawn from the compressor is dependent on the power behind your die grinder. Also, it is important that you choose an air compressor that can work at minimum volume and pressure to prevent your grinder motor from stalling.
