Air Die Grinder Buying Guide

Power

Small or big, professional or not, you want a grinder that packs good power. And for this, you need to look at the motor. The more power your motor can provide, the better the performance.

This factor also decides how much speed your device can handle, making it all the more important. When buying, look for grinders that have a motor power of at least 0.25 horsepower and you should be set.

After the power, you need to see the source. For a die grinder, there are a few options to choose from. You can choose between pneumatic, corded-electric, or cordless. Which one you go for depends on what you are doing and what you are comfortable with.

Pneumatic grinders work with compressed air and usually go a long way. If you have an air compressor, this is a good choice.

Cordless models are easy to maneuver, especially with outdoor work. However, you have to consider the battery power. Don’t pick one where you need to halt work to repeatedly charge your device.

Corded electric grinders eliminate this problem, but then again you will have to work around wires.

Every system has its benefits and limitations. You simply have to consider which factors you prefer over others.

Speed Control

Speed control is very important regardless of where you use the machine. That’s because as soon as you shift from one material to another, say from metal to plastic, you will need a change of speed.

Without it, you risk doing damage due to high pressure or experience a slowdown in work due to low pressure. Check if your desired product has speed control or not before purchasing.

Head

When buying grinders, you will find that some come with a right angle head, while others have a straight head. While this mostly depends on preference, right-angled grinders are more popular today.

They are more comfortable to use and can reach those tight, hard-to-reach spots. You can also mount them on a grinding wheel easily.

This is not to say that straight heads are too behind, it’s just you will have more options with a right angle.

Size

The size of a die grinder is very important and relevant to the kind of work you will be doing. For instance, if you are an occasional worker who does small projects at home like polishing surfaces, you do not have to go for a large size.

A smaller one will be more convenient to use, handle and store. For small projects, go for a ¼ inch die grinder.

For professionals, the requirements are higher. If you happen to work in a construction site or factory, opt for a larger size. It will be more heavy duty, helping to do your job faster, where a smaller machine will take a lot longer.

Safety

When buying air die grinder, you’ll probably want the powerful ones out there. But power and speed also make them more dangerous in case of accidents.

If you have kids at home, or are worried of mishandling the device, look for grinders that come with safety switches, locks or other safety measures that prevent accidents.
