Ingersoll Rand 8265-3-1 is a Super Par-A-Matic Series Self-Feed Air Drill designed for repeatable production drilling, fixture-mounted machining, and automated secondary machining. Its 0.75 HP (.56 kW) pneumatic motor provides a 350 RPM free speed through a double gear reduction, making this configuration suitable for controlled, low-speed drilling operations. The -1 configuration provides a 1-1/2 in. (38 mm) stroke, while the 1/2 in. capacity identifies the drill's standard capacity for compatible tooling. Product/stock code 2324830 corresponds to this model.
The Super Par-A-Matic self-feed mechanism uses a double-acting air piston for controlled forward and retract strokes. Needle-valve controls allow adjustment of the forward and retract movement, while the adjustment screw provides infinite stroke-length settings. The built-in four-way valve permits both manual and remote operation, allowing the drill to be integrated into suitable pneumatic production equipment. Ball-bearing spindle support provides precision spindle guidance, and the muffled exhaust helps provide quieter pneumatic operation. Manufacturer data specifies 250 lb (1112 N) thrust at 90 PSI, 2.9 ft³/cycle (82 L/cycle) air consumption at working speed, and a 77 dB(A) sound level.

Applications:
- Production drilling — performing repeatable drilling cycles where controlled pneumatic feed and retract movement are required.
- Fixture-mounted machining — integrating the drill into dedicated fixtures using the 1-1/2 in. stroke.
- Metalworking — drilling Type 304 stainless steel and SAE 1213 steel within the manufacturer's nominal capacities.
- Aluminum machining — drilling 2024-T4 aluminum within the specified nominal capacity.
- Automated secondary machining — incorporating controlled drilling cycles into suitable pneumatic production equipment.
- Production assembly — performing repeatable drilling operations where controlled pneumatic feed is advantageous.
FAQs:
- Q: What is the free speed of the 8265-3-1?
A: The 8265-3-1 has a 350 RPM free speed and uses double gear reduction. - Q: What does the “-1” configuration indicate?
A: The -1 configuration provides a 1-1/2 in. (38 mm) stroke. The 8265-3 model family is also available with a 3 in. stroke. - Q: What are the material-specific drilling capacities?
A: The nominal capacities are 5/16 in. (7.9 mm) in Type 304 stainless steel, 1/2 in. (12.7 mm) in SAE 1213 steel, 5/8 in. (15.9 mm) in 2024-T4 aluminum, and 11/16 in. (17.5 mm) in wood, medium or FRP. - Q: Is the 1/2 in. specification the drilling capacity for every material?
A: No. The 1/2 in. specification identifies the stated tool capacity and is also the nominal drilling capacity in SAE 1213 steel. The rated drilling capacity varies according to workpiece material. - Q: Can the 8265-3-1 be operated remotely?
A: Yes. The built-in four-way valve permits both manual and remote operation for suitable pneumatic control arrangements. - Q: What thrust does this self-feed drill provide?
A: The specified thrust is 250 lb (1112 N) at 90 PSI.
