Ingersoll Rand 8245-B45-3 is a Bant-A-Matic Series Self-Feed Air Drill for repetitive production drilling and fixture-mounted machining where controlled spindle feed and retract are required. This configuration combines a 0.25 HP pneumatic motor with a 4,400 RPM free speed and single gear reduction. The -3 version provides a 3 in. (76 mm) stroke, giving production fixtures additional feed travel for drilling cycles that require an extended stroke. The model is identified with a 3/16 in. capacity for steel applications.
The Bant-A-Matic self-feed mechanism uses a double-acting air piston for controlled forward and retract movement. Needle-valve controls allow the feed and retract strokes to be adjusted, while the adjustment screw provides infinite stroke-length settings. A built-in four-way valve supports manual or remote operation, allowing integration into suitable pneumatic control systems. Ball-bearing spindle support provides controlled spindle guidance, and the damped exhaust helps reduce operating noise. The manufacturer specification group also lists 90 lb (400 N) thrust at 90 PSI, 1.5 ft³/cycle (42 L/cycle) air consumption at working speed, and a 1/4 in. (6.4 mm) standard chuck capacity.

- The double-acting air piston provides controlled forward and retract strokes.
- Needle-valve controls allow adjustment of the forwarding and retracting strokes.
- The adjustment screw provides infinite stroke-length settings.
- The built-in four-way valve permits both manual and remote operation.
- Ball-bearing spindle support provides precision spindle guidance.
- The damped exhaust helps provide quieter pneumatic operation.
- The 1/4 in. standard chuck accommodates compatible drill tooling within the manufacturer's specified capacity.
NON-RETURNABLE. MADE TO ORDER.
Applications:
- Production drilling — performing repetitive holemaking operations where controlled pneumatic feed and retract movement are required.
- Fixture-mounted machining — integrating the drill into dedicated fixtures where the 3 in. stroke provides the necessary spindle travel.
- Metal fabrication — drilling compatible steel components within the manufacturer's stated capacity.
- Secondary machining — adding repeatable drilling cycles to manufacturing equipment without continuous manual feed control.
- Automated drilling equipment — using the four-way valve for manual or remote operation where the pneumatic control system supports it.
