Blackalloy - All Air, Inc.

Precision Drill and Tapping Units

Blackalloy drill units, automated drilling assemblies and drilling systems have enjoyed widespread success in small hole precision production drilling applications in metals, woods, plastics, and other drilling mediums. In addition, the versatility of these drill units makes them an excellent choice for many applications other than drilling, such as bottle capping, robotics, winding, etc. Blackalloy’s™ unique low-stress trilobe spindle is designed to transmit torque from the pulley to the spindle. All Air offers Blackalloy™ drill units in a full range of strokes, hydro-check (or feed control) equipment, spindle options including extended length with thru-holes, and many special modifications.

Product Lineup

Model 150/152/153 Self-Feeding Drill Units

Pneumatic Stroke, Self-Feeding Drill Units

Blackalloy model 150, 152, & 153 self-feeding drill units are automated self-feeding drills which can be actuated with air or oil. They are capable of producing thrusts of up to 182 lbs. with 100 psi air pressure and 364 lbs. with 200 psi oil pressure.

These units are usually used for drilling, reaming, boring and light milling applications, but can also be used whenever simultaneous rotary and linear motions are required. It can be mounted in any position, horizontal, vertical etc. As illustrated, it is supplied without a motor, but can be easily powered by an electric or air motor up to 1/3 hp. A simple pneumatic, or hydraulic control system is required to achieve forward and reverse stroke control.
