is a machine powered by an air motor driven by compressed air. Pneumatic power is used to drive a wide range of tools, both those requiring rotary motion, such as drills, and those requiring reciprocating motion, e.g., hammers and chisels. Pneumatic tool lubricants are generally the same types as those for compressors; however, the percussion forces in some pneumatic tools may demand special lubricants with EP properties.

Also see EP additive, rock drill lubricant.
