A system for processing a workpiece, including a rotary drive having a path along which a flow of a fluid is established during operation, a sensor in communication with the path, to generate a signal responsive to the flow of the fluid and not to generate the signal responsive to an absence of the flow, and a controller communicatively coupled to the sensor to enable the operation of the rotary drive subsequent to a termination of the signal if a duration interval thereof is greater than or equal to a predetermined value, and to prevent the operation if the duration interval of the signal is less than the predetermined value. The rotary drive may include a drill.

A foreign object debris (FOD) collection drill attachment for attaching to a drill includes with a drill guide bushing holder, a chip breaker bushing, an air supply line, a chip evacuation line, a chip collection hopper, and an air manifold. The drill guide bushing holder includes an inlet channel receiving air from the air supply line, an outlet channel, and a holder center channel. The inlet channel and the outlet channel each open into the holder center channel through which an end protrusion of the chip breaker bushing extends to break up FOD on a drill bit of the drill. The cross-sectional area of the inlet channel is smaller than the cross-sectional area of the outlet channel, creating a Venturi effect between the inlet channel and the outlet channel to pull FOD away from the drill bit and through the chip evacuation line to the chip collection hopper.

A handle for a hydraulically driven tool is provided reduces the amount of heat transmitted to the user of the tool as a result of the high temperature fluid flowing through the inner body of the handle. The inner body is formed of a heat transmissive material which has at least one channel through which the fluid flows. The handle has a number of properties which reduces heat transmission to the user, including standoffs, ribs and fastener receiving extensions.

A pneumatic motor with built-in striker mechanism mainly includes a cylinder, rotor set and output shaft lever. The rotor set has a rotary drum and flexible blades. The output shaft lever can be driven by the rotary drum. A chamber is formed into the rotary drum and a striking portion on the output shaft lever is located within the chamber. The built-in striker mechanism is placed in the chamber and has striking bulges protruded on the striking portion, movable hammers sleeved externally on the striking bulge and struts axially located on the rotary drum. This new pneumatic motor has the striker mechanism set into the rotary drum of the rotor set, thus reducing greatly the axial length and volume of the pneumatic motor and realizing ease-of-use.

The invention relates to a drill fire extinguishing device (1) having: a tool holder (13) to hold or be connected to a tool; a fluid connection to supply a fluid; a turbine with an impeller that has at least one stage with a plurality of runner blades connected to the tool holder (13) to drive it in a rotary and/or percussive fashion using drive fluid via the fluid connection. The drill fire extinguishing device (1) also has: at least one discharge opening (20) in a stationary wall (4) of the drill fire extinguishing device (1) communicating with a fluid chamber and/or a nozzle assembly (12) with one or more nozzles (18) in a stationary wall (4) of the drill fire extinguishing device (1) for dispensing the fluid and communicating with the fluid chamber. The invention also relates to a drill fire extinguishing system and a drill bit.

A compressed air storage device has a flexible, elongated tubular configuration in which the tube has an internal volume that is configured to store sufficient compressed air to drive a hand-held pneumatic tool. The compressed air storage device has a variable diameter along its length and an internal space that extends between and communicates with couplings disposed at opposed ends of the device.

A drilling apparatus and method for forming a countersunk hole into a structure. The drilling apparatus may include a drill motor housing assembly, a rotor/spindle assembly, a countersink cage, and a countersink cutter. The drill motor housing assembly may have an inlet air duct, the rotor/spindle assembly may have a first duct and the countersink cage may have a second duct. The countersink cutter may have a plurality of flutes formed into a cutting end thereof. The countersink cutter may also have a third duct formed therethrough and a plurality of exit ducts common with the flutes. Each duct of the drilling apparatus may be fluidly coupled such that inlet air may be forced through the inlet air duct, through the first duct, through the second duct, through the third duct, and then through the plurality of exit ducts during drilling via the drilling apparatus.
