Ingersoll Rand 8245-101-1 is a Bant-A-Matic Series Self-Feed Air Drill built for automated and fixture-mounted drilling where repeatable feed and retract movement are required. Its 0.25 HP pneumatic motor operates at a 10,000 RPM free speed, while the double gear reduction configuration provides the spindle drive arrangement specified for this model. The 8245-101-1 has a 3/16 in. (4.8 mm) nominal drilling capacity in steel, a 1-1/4 in. (32 mm) stroke, and 90 lb (400 N) thrust at 90 PSI.
The self-feed mechanism uses a double-acting air piston for controlled forward and retract strokes. A built-in four-way valve permits both manual and remote operation, while needle-valve controls allow the forward and retract rates to be adjusted. The adjustment screw provides infinite stroke-length settings within the model's specified stroke configuration. Ball-bearing spindle support provides controlled spindle rotation, and the muffled exhaust helps reduce operating noise. Air consumption is 1.5 ft³/cycle (42 L/cycle) at working speed, with a 77 dB(A) sound level.

Applications:
- Production drilling — performing repetitive holemaking operations where controlled pneumatic feed and retract movement are required.
- Fixture-mounted machining — integrating a self-feed drill into dedicated production fixtures and automated drilling equipment.
- Metalworking — drilling small holes in materials within the manufacturer's stated drilling-capacity range.
- Secondary machining — adding repeatable drilling operations to manufacturing processes without relying on continuous manual feed.
- Automated assembly operations — using the manual or remote four-way valve configuration where controlled drill cycling is required.
