When a production drilling operation requires very high spindle speed with controlled pneumatic feed, the Ingersoll Rand 8265-171-3 provides a 17,000 RPM free speed from a 0.75 HP (.56 kW) pneumatic motor with single gear reduction. This Super Par-A-Matic Series Self-Feed Air Drill uses a 3 in. (76 mm) stroke, extending the spindle travel available for fixture-mounted and automated drilling operations. The model is rated at 1/2 in. capacity and uses compressed air for both spindle rotation and feed/control functions.
The self-feed mechanism uses a double-acting air piston for controlled forward and retract strokes. Needle-valve controls adjust the forward and retract movement, while the adjustment screw provides infinite stroke-length settings. Ball-bearing spindle support provides precision spindle guidance, and the muffled exhaust helps provide quieter pneumatic operation. The tool can be installed with simple pneumatic circuitry and used individually or with other compatible Ingersoll Rand pneumatic and electric tools. For the 17,000 RPM configuration, the manufacturer notes that the spindle uses a collet rather than the standard chuck arrangement used on other models in the series.

Applications:
- Aerospace production — performing small-diameter rivet and mounting-hole operations in suitable production fixtures.
- Metal fabrication — producing small holes in sheet metal and compatible components where the specified material capacities apply.
- Fixture-mounted machining — integrating the self-feed drill into dedicated equipment where a 3 in. stroke is required.
- Automated secondary machining — incorporating repeatable pneumatic drilling cycles into suitable production machinery.
- Manufacturing assembly — performing controlled drilling operations where high spindle speed and pneumatic feed are required.
FAQs:
- Q: What is the free speed of the 8265-171-3?
A: The 8265-171-3 has a 17,000 RPM free speed and uses single gear reduction. - Q: What does the “-3” configuration indicate?
A: The -3 configuration provides a 3 in. (76 mm) stroke, giving the spindle additional travel compared with the 1-1/2 in. configuration. - Q: What are the material-specific drilling capacities?
A: The manufacturer lists no nominal capacity for Type 304 stainless steel, 1/64 in. (0.4 mm) for SAE 1213 steel, 3/32 in. (2.4 mm) for 2024-T4 aluminum, and 3/32 in. (2.4 mm) for wood, medium or FRP. - Q: Does the 17,000 RPM model use a standard chuck?
A: The manufacturer specifically notes that the 17,000 RPM and 19,000 RPM units use a collet in the spindle. Verify the required collet and tooling configuration before ordering. - Q: What thrust does the 8265-171-3 provide?
A: The specified thrust is 250 lb (1112 N) at 90 PSI. - Q: What air supply is recommended?
A: The specified operating pressure is 90 PSI (6.2 bar), with a 1/4 in. NPT male air inlet and recommended 3/8 in. hose I.D.
