Ingersoll Rand 8268-A25-3 Self-Feed Twin Drill | 3/8" Capacity | 0.75 HP | 2,500 RPM | Single Gear Reduction

Built for automated production drilling and close-center machining, the Ingersoll Rand 8268-A25-3 Self-Feed Twin Drill combines a 3/8" steel capacity, 0.75 HP pneumatic motor, and 2,500 RPM free speed for repeatable drilling operations in production environments. Its single gear reduction supports the high spindle speed required for this model, while the twin-drill configuration allows two machining operations to be performed during each cycle. Adjustable dual spindle heads provide flexibility when configuring the tool for different hole-center requirements.

The 8268-A25-3 features a 3.0" stroke length for extended axial travel during the drilling cycle. The Super Par-A-Matic Series uses a self-contained pneumatic design with built-in cycle, feed-rate, and motor controls. Adjustable spindles allow the tool to be configured as machining requirements change, making this model suitable for production fixtures and automated drilling applications.

FAQs:

• Q: What is the drilling capacity of the 8268-A25-3?
  A: The model is identified as a 3/8" (9.5 mm) capacity drill for steel. The published nominal capacities are 1/16" (1.6 mm) for stainless steel Type 304, 1/4" (6.4 mm) for Steel SAE 1213, 5/16" (7.9 mm) for Aluminum 2024-T4, and 5/16" (7.9 mm) for medium wood or FRP.
• Q: What does single gear reduction mean?
  A: Single gear reduction uses one stage of gearing to reduce the motor speed before the spindle, providing the specified 2,500 RPM free speed for this model.
• Q: What is the stroke length?
  A: The 8268-A25-3 has a 3.0" (76 mm) stroke length.
• Q: What is a self-feed twin drill?
  A: A self-feed twin drill combines two adjustable drilling spindles with pneumatic spindle rotation and feed functions, allowing two machining operations to be performed during a production cycle.
• Q: Can the spindle positions be adjusted?
  A: Yes. The Super Par-A-Matic Series features adjustable dual spindle heads to accommodate changing machining requirements and close-center drilling applications.
