Ingersoll Rand 8245-B45-1 Self-Feed Air Drill | 3/16" Capacity | .25 HP | 4,400 RPM | Single Gear Reduction

Ingersoll Rand 8245-B45-1 is a Bant-A-Matic Series Self-Feed Air Drill designed for controlled, repetitive drilling operations where pneumatic feed and retract are required. This model combines a 0.25 HP pneumatic motor with a 4,400 RPM free speed and single gear reduction. The 8245-B45-1 uses a 1-1/4 in. stroke and provides 90 lb (400 N) thrust at 90 PSI for controlled self-feed drilling.

The self-feed mechanism uses a double-acting air piston for forward and retract movement, while a built-in four-way valve permits manual or remote operation. Needle-valve controls allow adjustment of forward and retract feed rates, and an adjustment screw provides infinite stroke-length settings. Ball-bearing spindle support helps maintain controlled spindle operation, while the muffled exhaust reduces operating noise. The drill has a 1/4 in. (6.4 mm) standard chuck capacity, 1.5 ft³/cycle (42 L/cycle) air consumption at working speed, and a 77 dB(A) sound level.

• A double-acting air piston provides controlled feed and retract strokes.
• The built-in four-way valve permits manual or remote operation.
• Needle-valve controls allow adjustment of the forward and retract feed rates.
• An adjustment screw provides infinite stroke-length settings within the model's stroke range.
• Ball-bearing spindle support provides controlled spindle operation.
• A muffled exhaust helps reduce operating noise during 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 drilling operations where controlled pneumatic feed and retract are beneficial.
• Fixture-mounted machining — integrating the self-feed drill into dedicated drilling fixtures and production equipment.
• Secondary machining — adding repeatable drilling operations to manufacturing processes without continuous manual feed control.
• Automated drilling systems — using the four-way valve for manual or remote operation where the installation supports it.
• Small-hole drilling — using compatible tooling and materials within the manufacturer's stated drilling-capacity requirements.
