The 8266-A7-2EU 51mm Stroke Ingersoll Rand Par-A-Matic Valve-In-Head Self-Feed Offset Air Drill is an engineered production solution designed specifically for applications where conventional drill configurations cannot reach. As part of the ARO Automatic Offset Drill family, the 8266-A7-2EU 51mm Stroke Ingersoll Rand Par-A-Matic Valve-In-Head Self-Feed Offset Air Drill is built to accommodate unusual part geometries, restrictive fixture layouts, and tight-clearance machining environments. Its offset spindle design allows operators to produce holes in locations that standard inline drills cannot access, and multiple units may be fixture-mounted to achieve hole center-line distances as small as 1.5”?ideal for close-center automated drilling requirements.

Like all ARO Automatic Production Tools, the 8266-A7-2EU 51mm Stroke Ingersoll Rand Par-A-Matic Valve-In-Head Self-Feed Offset Air Drill is easily installed and requires only simple pneumatic circuitry for operation. It can function as a stand-alone automated drill or be integrated seamlessly with other ARO pneumatic or electric components within a larger machining system. Using compressed air for both spindle rotation and feed/control functions, this offset drill provides a compact, dependable solution for achieving consistent hole quality in challenging production environments.

The 8266-A7-2EU 51mm Stroke Ingersoll Rand Par-A-Matic Valve-In-Head Self-Feed Offset Air Drill incorporates a built-in four-way valve to support both manual and remote actuation, giving operators and integrators full flexibility over control schemes. A double-acting air piston delivers smooth, highly controlled forward and retract strokes, while dedicated feed-rate adjustment screws on each stroke allow precise tuning for optimal cycle time and hole quality. Infinite stroke-length adjustment is supported up to the full 2.0” maximum, enabling fast adaptation to varying part specifications or process requirements. A muffled exhaust system reduces operational noise for a more comfortable work environment, and multiple mounting bracket options ensure compatibility with diverse installation needs.

Engineered for accessibility, precision, and reliability, the 8266-A7-2EU 51mm Stroke Ingersoll Rand Par-A-Matic Valve-In-Head Self-Feed Offset Air Drill is an ideal choice for automated production setups requiring accurate hole placement in areas that standard self-feed drills simply cannot reach.
