Ingersoll Rand Hi-Thrust Self-Feed Drill PN 8670-4-3
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 easi ly installed, requiring only simple pneumatic circuitry. Hi-Thrust Drills can also be used in conjunction with other pneumatic and electric ARO Automatic Production Tools.
Additional features / benefits include—
- 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 reposition ing the tool.
- Both coarse and fine stroke length adjustments enables quick, accurate setups.
- Control module is a 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 en vironment.
- Exhaust may be piped away.
