An air driven tool for use in a machining center, the air driven tool including an adjustable speed regulator and a turbine. The turbine is driven by pressurized air directed thereto. The turbine is rotatable about an axis. A flow of the air is regulated by the adjustable speed regulator. The adjustable speed regulator includes a biasing member, an inclined annular surface, a regulator plate and a plurality of moveable bearings. The inclined annular surface has an angle relative to the axis. The plurality of movable bearings are positioned between the inclined annular surface and the regulator plate. The biasing member biases the inclined annular surface and/or the regulator plate toward each other.
