The 8258-C5-1 1-1/4” Stroke Ingersoll Rand Par-A-Matic Valve-In-Head Self-Feed Twin Air Drill is a high-efficiency dual-spindle production tool engineered to perform two machining operations per cycle with exceptional accuracy. Designed for hole center distances from 3/8” to 3-3/4”, the 8258-C5-1 1-1/4” Stroke Ingersoll Rand Par-A-Matic Valve-In-Head Self-Feed Twin Air Drill is an ideal solution for close-center drilling challenges where speed, repeatability, and part quality are essential. By executing two operations simultaneously, this Par-A-Matic Twin Air Drill significantly reduces machining time and parts handling while maintaining the precision required in demanding aerospace and industrial environments.

Like all Par-A-Matic automatic production tools, the 8258-C5-1 1-1/4” Stroke Ingersoll Rand Par-A-Matic Valve-In-Head Self-Feed Twin Air Drill is fully self-contained, using compressed air for both spindle rotation and feed/control functions. Its compact rotary-vane motors deliver an excellent power-to-size ratio that minimizes tool weight and gives integrators greater design flexibility.

The 8258-C5-1 1-1/4” Stroke Ingersoll Rand Par-A-Matic Valve-In-Head Self-Feed Twin Air Drill incorporates a built-in four-way valve for both manual and remote actuation, making it adaptable to a wide variety of production workflows. Adjustable dual spindles enable easy reconfiguration as machining requirements evolve, while a double-acting air piston ensures smooth, controlled forward and retract strokes. Needle valve controls allow fine-tuning of motion characteristics, and an integrated adjustment screw provides infinite stroke-length settings up to the full rated capability. Ball bearing spindle support delivers long service life and consistent precision under continuous production demands. A muffled exhaust system further enhances operator comfort by reducing overall noise levels.

Engineered to streamline throughput while improving accuracy and part uniformity, the 8258-C5-1 1-1/4” Stroke Ingersoll Rand Par-A-Matic Valve-In-Head Self-Feed Twin Air Drill is an excellent choice for manufacturers seeking a flexible, reliable, and high-performance dual-spindle drilling solution for automated machining environments.
