When Choosing an Air Die Grinder there are a few things you should consider.

• Does the Air Die Grinder have an adjustable speed switch?  It will allow you to have more control over the tool if you are able to control the speed.

• Where does the Air Die Grinder vent its air?  We would recommend a rear venting tool in most cases.  When you are using the grinder you do not want air blowing over the work surface.

• What is the top speed of the Air Die Grinder? The faster the better in most cases you can always slow the speed with lower air pressure on the compressor or the adjustable speed switch recommended above.

• What is the average air consumption of the Air Die Grinder?  They are rated by CFM (cubic feet per minute) and you need to make sure that your compressor will handle the air usage of the Die Grinder.
