Ingersoll Rand 8245-203-1 is a Bant-A-Matic Series Self-Feed Air Drill designed for automated drilling applications where controlled spindle rotation and feed are required. This pneumatic drill combines a 0.25 HP air motor with a high 19,000 RPM free speed and single gear reduction, making it suited to small-diameter drilling in production and secondary machining operations. The model has a 3/16 in. nominal chuck capacity and a 1-1/4 in. stroke length.
The 8245-203-1 provides 90 lb (400 N) thrust and uses approximately 1.5 ft³/cycle (42 L/cycle) of air at working speed. Its self-feed design uses pneumatic feed and control functions for forward and retract movement, while needle-valve controls allow adjustment of feed and retract strokes. An adjustment screw provides infinite stroke-length settings, and ball-bearing spindle support is used for precision and service life. The tool has a 77 dB(A) sound level and a standard 1/4 in. chuck capacity.

- Needle-valve controls allow adjustment of the forward and retracting strokes.
- The adjustment screw provides infinite stroke-length settings for application-specific drilling requirements.
- Ball-bearing spindle support is designed to provide precision and long service life.
- The single gear reduction configuration provides the 19,000 RPM free speed specified for this model.
- The damped exhaust helps reduce operating noise during use.
- The 1/4 in. standard chuck accommodates the drill tooling specified for the application.
NON-RETURNABLE. MADE TO ORDER.
Applications:
- Automated drilling — integrating controlled drilling into fixtured or production machining processes.
- Secondary machining — performing repetitive drilling operations where consistent feed and retract control are required.
- Small-diameter drilling — working with the nominal drilling capacities specified for steel, aluminum, and wood or FRP materials.
- Production drilling — using the self-feed mechanism to reduce the need for manual feed control during repetitive operations.
- Fixture-based machining — incorporating a compact pneumatic drill into dedicated drilling equipment where the model's speed, stroke, thrust, and chuck capacity are appropriate.
