Ingersoll Rand 8670-13-3AM High-Thrust Pneumatic Self-Feed Drill | 3" Stroke | 5/8" Capacity | 1.25 HP | 1,350 RPM

Ingersoll Rand 8670-13-3AM High-Thrust Pneumatic Self-Feed Drill combines a 1.25 HP pneumatic motor with a manufacturer-rated 1,350 RPM free speed and 3-inch stroke. Part of the High-Thrust 8670 Series, this automatic feed drill provides 500 lbs of thrust at 90 PSI, supplying the forward force needed for drilling suitable metals and other machinable materials. Its 3/4-inch capacity chuck accommodates compatible cutting tools for production drilling applications. The self-feed arrangement automatically advances and retracts the spindle, supporting repeatable machining cycles without continuous manual feed control.

The 8670-13-3AM uses a dual-piston feed mechanism that develops high forward thrust for material penetration and supports rapid spindle retraction. An adjustable hydraulic check regulates the feed rate, helping control cutting progress, chip formation, and drill breakthrough. Dead-stop and dwell adjustments provide repeatable drilling depth control, while a pneumatic control module coordinates the automatic cycle and motor functions. The model's A drive configuration identifies the 3/4-inch chuck, and its M exhaust configuration identifies the muffler arrangement. Operating with a 3/8-inch NPT male air inlet and a recommended 5/8-inch inside-diameter air hose, this self-feed drill can be integrated into dedicated manufacturing fixtures and automated drilling equipment.

Applications:

• Automated production drilling: Performing repeated drilling cycles in dedicated fixtures and manufacturing equipment.
• Stainless steel and carbon steel machining: Producing holes in suitable workpieces within the manufacturer's nominal drilling capacities.
• Aluminum component manufacturing: Drilling production parts, housings, and machined assemblies requiring consistent feed control.
• Machine-integrated drilling stations: Incorporating automatic spindle feed and retraction into pneumatic production systems.
• Wood and composite machining: Drilling compatible medium-density wood and fiber-reinforced plastic components with suitable cutting tools.

FAQs:

• Q: What are the operating speed and stroke length of the Ingersoll Rand 8670-13-3AM?
  A: The manufacturer lists a free speed of 1,350 RPM and a 3-inch automatic feed stroke. The 1,300 RPM figure in the supplied product title should be corrected to 1,350 RPM to match the manufacturer specification.
• Q: What materials can the 8670-13-3AM drill?
  A: The manufacturer specifies nominal drilling capacities of 5/16 inch in Type 304 stainless steel, 11/32 inch in SAE 1213 steel, 5/8 inch in 2024-T4 aluminum, and 3/4 inch in medium wood or fiber-reinforced plastic. Actual performance depends on tooling, feed settings, and workpiece conditions.
• Q: What do the A and M suffixes indicate in the 8670-13-3AM model number?
  A: The A identifies the 3/4-inch capacity chuck configuration, while M identifies the muffler exhaust option. These suffixes distinguish the model's drive and exhaust arrangement from other 8670 Series configurations.
• Q: How does the self-feed mechanism control drilling movement?
  A: A pneumatic feed system advances and retracts the drill spindle automatically. The adjustable hydraulic check controls forward feed rate, and dead-stop and dwell settings help maintain the intended drilling depth and cycle operation.
• Q: What compressed-air supply is required for the 8670-13-3AM?
  A: Ingersoll Rand recommends 90 PSI operating pressure, a 3/8-inch NPT male air inlet, and a 5/8-inch inside-diameter air hose. Air consumption is specified as 5.0 cubic feet per typical six-second cycle, rather than a continuous CFM rating.
