Abstract: A pneumatic tool includes, but is not limited to, an air motor cylinder defining an interior configured to receive an air motor and further defining an inlet configured to receive pressurized air to supply to the air motor; a tool handle defining a source fluid passageway fluidically coupled between the inlet and an air inlet configured to receive pressurized air, the source fluid passageway configured to direct a first portion of pressurized air received by the inlet to the inlet of the air motor cylinder; an air pressure indicator coupled to the air motor cylinder and configured to provide an indication of a dynamic air pressure of the pneumatic tool; and an indicator fluid passageway fluidically coupled between the air pressure indicator and the source fluid passageway, the indicator fluid passageway configured to divert a second portion of pressurized air received by the air inlet to the air pressure indicator.
