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.


  • Adjustable hydraulic check provides positive feed rate control for fine adjustment of chip size or breakthrough control.
  • "Dead stop" and "dwell" control offer repeatable depth accuracy within .001"
  • Heavy-duty cast iron housing for rigid mounting.
  • Constant tool length, regardless of spindle speed, allows speed change without repositioning the tool.
  • Both coarse and fine stroke length adjustments enables quick, accurate setups.
  • Control module ia s complete, replaceable unit and can be easily removed without tool disassembly.
  • Modular motor and gearing units enable fast, easy speed changes and servicing.
  • Single exterior lubrication point for entire gear train simplifies preventative maintenance.
  • Muffled exhaust for a more comfortable work environment.
  • Exhaust may be piped away.
