Air Die Grinder Buying Guide

If you can pick the best air die grinder, it can last a lifetime. So, you check the grinder wisely before making the final purchase. These are some of the features to look for while buying an air die grinder. Let’s check them out.

Rotating Speed

The faster a grinder will spin, the harder it can work. The speed of the device controls the speed of the burr. The faster the burr will hit the metal through rotation, the deeper will be its effect. That’s why it is an important factor to notice.

Normally the rotating speed of such devices ranges from 8,000 RPM to 34,000 RPM. For an average air die grinder, the speed is 20,000 RPM. The grinder with a speed around 20,000 RPM is considered a powerful one. You should look up for grinders of relevant speed. The faster your grinder moves, the better is its service.


You should check if the air grinder can offer you with maximum usability. It is very easy to work on flat surfaces. They are open, and you can work on them very easily. But sometimes you face the challenge when you have to work on areas which are inside a hollow space or any tight space. Your straight air grinder would not work in those unreachable areas.

For working on those surfaces, there are some angled grinders. So many companies manufacture angled grinder along with the straight ones for the convenience of their users. You should look for that grinder which is convenient for your use.


Safety is an important issue to be given priority for using machines like an air die grinder. With slight ignorance, you can have a very bad injury. It might cost you more than you imagine. That’s why you must be very cautious while handling such a device, and the device itself must have the safety measures.

Most air die grinders have a pressure plate switch for easy use. It remains fixed on the handle for the convenience of turning on and off the device.

However, with a slight push on the plate, you can turn on the tool. Even by accident, if you drop it or it gets pushed by something, it has chances of getting started. In unwanted conditions, if the machine gets started due to these causes, it can be very dangerous. The device has the capability of harming you very badly under such circumstances.

To avoid these dangers, the most common safety offered by these tools is the presence of lever throttle. The lever throttle is given on the pressure plate switch so that it resists force and offers rigidity to the switch.

It is a very important feature for ensuring safety. You must check if the grinder you are buying has this important feature.

Size, Shape and Weight

For workaholics like you who love to work more and for longer hours, it is an important feature to look for. The dimension of the device is vital as you will be carrying it for a long time.

If the device is larger, it would not be very convenient for holding. Besides, the size of the object will also affect its weight. Whereas the lighter the weight the easier it is to carry.

The shape is also a big factor to consider. Many grinders have unique handles with versatile shapes. For your convenience, the brands come up with different designs and shapes. The perfect shape can help you hold the device with more grip and suitable for bearing it for hours.
