The air angle grinder is a powerful and useful tool to have around the shop. For as little as .99, you can have an angle grinder that is capable of 20,000 rpm's in your hand to grind or cut to your heart's desire. The secret to not overheating a device like this is in their ball bearing use in the working mechanism of the tool. When lubricated properly, this will spin at a high velocity for any needed time. The average air inlet of a tool with this capacity is ¼ inch collet that needs 3 CFM at 90 psi. The weight of this tool is only 1 ¼ lbs.
There are also larger more powerful air angle grinders available. The top of the line models will require two hands to operate safely. With rpm's reaching 12,000, nearly a full horsepower of torque is possible but the CFM requirement is 9.
Cordless Angle Grinder
The more power that is desired will require a greater flow of air through your tool. If looking for brute force, go with the highest CFM. Speed is relevant but not if the power is also there.
As with all air or pneumatic tools, they must be lubricated. If the air supply does not have an oil drip system in it, then an addition of oil to the tool through the air inlet before each use is recommended. Marvelous Mystery Fluid or ATF are the two most common in the professional shops.
The air angle grinder is an indispensible part of any well-equipped metal or mechanical shop. Most have more than one.
