Ingersoll Rand 8245-B30-2 is a Bant-A-Matic Series Self-Feed Air Drill built for repetitive and fixture-mounted drilling where controlled spindle feed and retract movement are required. This model combines a 0.25 HP pneumatic motor with a 2,700 RPM free speed and single gear reduction. The -2 configuration provides a 2 in. stroke, giving production tooling and automated fixtures additional feed travel compared with the shorter-stroke version.
The self-feed mechanism uses a double-acting air piston for controlled forward and retract strokes. A built-in four-way valve permits manual or remote operation, while needle-valve controls allow adjustment of forward and retract stroke rates. An adjustment screw provides infinite stroke-length settings. Ball-bearing spindle support helps maintain controlled spindle operation, and the muffled exhaust helps reduce operating noise. The tool uses a 1/4 in. standard chuck and is listed for a 3/16 in. capacity.
