Built for repetitive production drilling and fixture-mounted machining, the Ingersoll Rand 8245-101-3 is a Bant-A-Matic Series Self-Feed Air Drill combining a 0.25 HP pneumatic motor with a 10,000 RPM free speed and double gear reduction. The -3 configuration provides a 3 in. (76 mm) stroke, giving production fixtures additional feed travel for drilling cycles that require more spindle movement. The model is listed with a 3/16 in. capacity and is suited to repetitive drilling operations where controlled pneumatic feed and retract movement are required.
The Bant-A-Matic self-feed system uses a double-acting air piston to control forward and retract strokes. Needle-valve controls allow the feed and retract rates to be adjusted, while the adjustment screw provides infinite stroke-length settings. A built-in four-way valve permits manual or remote operation, allowing the drill to be incorporated into suitable pneumatic control systems. Ball-bearing spindle support provides controlled spindle guidance, and the muffled exhaust helps reduce operating noise. The drill uses a 1/4 in. (6.4 mm) standard chuck and provides 90 lb (400 N) thrust at 90 PSI.

- 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 production fixtures where the 3 in. stroke provides the required feed travel.
- Secondary machining — adding repeatable drilling cycles to manufacturing equipment without continuous manual feed control.
- Metal fabrication — drilling compatible components within the manufacturer's stated capacity.
- Automated drilling systems — using the four-way valve for manual or remote operation where the pneumatic installation supports controlled drill cycling.
FAQs:
- Q: What is the free speed of the 8245-101-3?
A: The 8245-101-3 has a 10,000 RPM free speed. - Q: What does the “-3” suffix indicate?
A: The -3 configuration identifies the 3 in. (76 mm) stroke version of the 8245-101 model family. - Q: What does double gear reduction mean?
A: It identifies the double gear reduction configuration used in the spindle drive of this 10,000 RPM model. - Q: What is the motor power?
A: The drill uses a 0.25 HP (.20 kW) pneumatic motor. - Q: How much thrust does the drill provide?
A: The specified thrust is 90 lb (400 N) at 90 PSI. - Q: What is the standard chuck capacity?
A: The standard chuck capacity is 1/4 in. (6.4 mm). - Q: Can the 8245-101-3 be operated remotely?
A: Yes. The built-in four-way valve permits both manual and remote operation. - Q: What is the advantage of the 3 in. stroke?
A: The longer stroke provides additional spindle travel for fixtures and drilling cycles that require more feed movement than the shorter 1-1/4 in. and 2 in. configurations.
