Ingersoll Rand 8268-A6-1 Self-Feed Twin Drill | 3/8" Capacity | 0.75 HP | 650 RPM | Double Gear Reduction

For automated production drilling where two holes can be machined during the same cycle, the Ingersoll Rand 8268-A6-1 Self-Feed Twin Drill combines a 3/8" steel drilling capacity with 0.75 HP pneumatic power and a 650 RPM free speed. Its double gear reduction provides the lower spindle speed needed for controlled drilling, while the twin-drill configuration supports close-center machining in production fixtures and automated equipment.

The 8268-A6-1 uses a 1-1/2" stroke and belongs to the Super Par-A-Matic Series. The tool's spindle centers can be adjusted from 3/4" to 3-3/4", allowing the two drilling positions to be configured for different part and fixture requirements. Performance data is specified at 90 PSI (6.2 bar), with a standard 3/8" chuck capacity listed for the series.

Type: Self-Feed Twin Drill | Series: Super Par-A-Matic | Capacity: 3/8" (9.5 mm), Steel | Power: 0.75 HP (0.56 kW) | Free Speed: 650 RPM | Gear Reduction: Double | Stroke Length: 1-1/2" (38 mm) | Thrust @ 90 PSI: 250 lbs (1112 N) | Air Consumption: 2.9 ft³/cycle (82 L/cycle) | Sound Level: 77 dB(A)

Features:

• Twin-spindle configuration allows two drilling operations to be performed during a production cycle.

• 3/8" steel capacity supports production drilling of components within the specified nominal capacity.
• 1-1/2" stroke provides the specified axial travel for the drilling cycle.
• Adjustable spindle centers from 3/4" to 3-3/4" accommodate different close-center machining requirements.
• Double-acting pneumatic feed provides controlled forward and retract strokes.
• Performance data is specified at 90 PSI (6.2 bar) operating pressure.
• Muffled exhaust helps manage operating sound in production environments.

NON RETURNABLE. MADE TO ORDER.

Applications:

• Automated production drilling where two holes are machined during each cycle.
• Close-center drilling applications requiring adjustable spindle spacing.
• Fixture-based machining of steel components within the specified 3/8" capacity.
• Production equipment requiring pneumatic spindle rotation and controlled feed.
• Manufacturing operations where repeatable drilling cycles can reduce parts handling.

FAQs:

• Q: What is the drilling capacity of the 8268-A6-1?
  A: The Super Par-A-Matic Series has a nominal drilling capacity of 3/8" (9.5 mm) in steel. Actual capacity varies by workpiece material and drilling conditions.
• Q: What does double gear reduction mean?
  A: Double gear reduction uses two stages of gearing to reduce spindle speed from the pneumatic motor, providing the specified 650 RPM free speed for this model.
• Q: How far apart can the twin spindles be positioned?
  A: The Super Par-A-Matic Series provides spindle-center adjustment from 3/4" to 3-3/4" (19 to 95 mm).
• Q: What is the stroke length?
  A: The 8268-A6-1 has a 1-1/2" (38 mm) stroke length.
• Q: What operating pressure is used for the published performance data?
  A: The manufacturer specifies the performance data at 90 PSI (6.2 bar) operating pressure.
