Pneumatic Drill Units

The air motor characteristics of Airmachines' Self Feed Units give optimum life to the drill bit and produce an optimum quality hole. As the bit dulls, the motor slows and torque increases, extending cutting ability. This motor characteristic and the variable thrust of the air cylinder balance both the torque and thrust. The result is optimum cycle time for a given material and drill bit, limited only by the maximum capacity of the unit.

Features:
Each basic unit is supplied with a standard 3/8" - 24 UNF threaded output spindle with a standard drill chuck. The unit is setup to utilize the common air supply port for powering both the air motor and cylinder. A combined supply means the cylinder only utilizes the backpressure of the air motor. This is appropriate for most applications.
