Ingersoll Rand 8265-46-1 Self-Feed Air Drill | 1/2" Capacity | .75 HP | 4,600 RPM | Single Gear Reduction

Ingersoll Rand 8265-46-1 is a Super Par-A-Matic Series Self-Feed Air Drill built for production assembly engineering, fixture-mounted drilling, and automated secondary machining. Its 0.75 HP (.56 kW) pneumatic motor delivers a 4,600 RPM free speed through a single gear reduction, while the 1-1/2 in. (38 mm) stroke provides controlled spindle travel for repeatable drilling cycles. The drill has a 1/2 in. (12.7 mm) standard chuck capacity, while actual nominal drilling capacity varies by material, including 1/8 in. in SAE 1213 steel, 1/4 in. in 2024-T4 aluminum, and 5/16 in. in wood, medium or FRP.

Compressed air powers both spindle rotation and the feed/control functions. The double-acting air piston provides controlled forward and retract strokes, while needle-valve controls adjust those movements. An adjustment screw provides infinite stroke-length settings, and the built-in four-way valve permits manual or remote operation. Ball-bearing spindle support provides precision spindle guidance, while the muffled exhaust helps reduce operating noise. The manufacturer specifies 250 lb (1112 N) thrust at 90 PSI, 2.9 ft³/cycle (82 L/cycle) air consumption at working speed, and a sound level of 77 dB(A).

Applications:

• Aerospace assembly — producing rivet and mounting holes in suitable fixture-mounted production operations.
• Appliance manufacturing — drilling repeatable panel and frame holes during production assembly.
• Metal fabrication — producing controlled holes in sheet-metal and cast-component work within the specified material capacities.
• Vehicle components — drilling compatible engine-mount, hinge, and body-component holes using suitable fixtures.
• Furniture and cabinet production — producing repeatable dowel, hinge, pilot, and related holes where the specified tooling and material capacities apply.
• Recreational vehicle manufacturing — performing repeatable drilling operations on compatible ATV, snowmobile, and trailer components.

FAQs:

• Q: What is the free speed of the 8265-46-1?
  A: The 8265-46-1 has a 4,600 RPM free speed and uses single gear reduction.
• Q: What does the “-1” configuration indicate?
  A: The -1 configuration provides a 1-1/2 in. (38 mm) stroke. The 8265-46 family is also available in a longer-stroke configuration.
• Q: Is the 1/2 in. capacity the maximum hole size?
  A: The 1/2 in. specification identifies the standard chuck capacity and the capacity of the Super Par-A-Matic series in steel. The actual nominal drilling capacity of this model varies by material and is 1/8 in. in SAE 1213 steel, 1/4 in. in 2024-T4 aluminum, and 5/16 in. in wood, medium or FRP.
• Q: What thrust does the 8265-46-1 provide?
  A: The manufacturer specifies 250 lb (1112 N) thrust at 90 PSI.
• Q: Can this self-feed drill be used with remote controls?
  A: Yes. The built-in four-way valve permits both manual and remote operation for suitable pneumatic production equipment.
• 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.
