High-Thrust 8670 Series Pneumatic Self Feed Drills

8670-28-1, Self Feed Drill

High-Thrust 8670 Series

5/8" (15.9 mm) Capacity, Steel 1.25 HP (.93 kW)

ARO Hi-Thrust Automatic Feed Drills are designed for increased material removal rates of standard alloys and non-ferrous materials. Their high power and thrust also enable the machining of even the most demanding materials, including titanium and high-nickel alloys.

ARO Hi-Thrust Drills feature a dual piston which develops the increased thrust for fast penetration and reduced cycle times. The tools are fully automatic, with all cycle and motor functions regulated by a single control module. They are easily installed, requiring only simple pneumatic circuity. Hi-Thrust Drills can also be used in conjunction with other pneumatic and electric ARO Automatic Production tools.

Features

  • Adjustable hydraulic check provides positive feed rate control for fine adjustment of chip size or breakthrough control.
