In car maintenance and repairs or in metalwork, an angle grinder is used for cutting, grinding and buffing. An angle grinder can even be used for sanding surfaces and edges on certain materials, providing the tool is equipped with the right disc. Here are some of those applications, as well as their corresponding cfm levels: Angle grinding. However, it’s important to remember the varying cfm levels should be multiplied by four when continuous usage comes into play. When used intermittently, standard-sized tools for certain applications have specific air pressure requirements. So how do you know how much air pressure is needed for a given application? Air tools made for general use with portable air compressors typically require 0 to 5 cubic feet per minute (cfm) at 70 to 90 pounds per square inch (psi), whereas with larger tools connected to stationary systems, the requirements usually exceed 10 cfm at 100 to 120 psi. However, it’s important to know the air pressure requirements of a given tool or application.Ĭontact Us Learn More Find a Dealer Near You When it comes to cutting hard materials and loosening long-tightened bolts, an air-powered tool can instantly perform what would otherwise be impossible. Air compressors and pneumatic tools make it possible to achieve in seconds what might take hours to accomplish by hand.
