ABSTRACT:
A speed limiter for setting the speed of an air tool has a flow passage body which screws into the air inlet of the tool. The body defines an axial air flow path therethrough with an annular land adjacent to internal threads. An adjusting insert is threaded to the internal threads and has a pair of opposed axially extending grooves formed in its periphery which extend further radially inward than the land. The size of the air flow passage and therefore the speed of the tool is varied by adjusting the insert toward or away from the land.
