Ingersoll Rand 7LN3A44 Right Angle Air Drill 0.75 Hp

Product Description

The INGERSOLL RAND 7LN3A44 is a right angle pneumatic drill built for professionals who need torque and access in tight spaces. Powered by compressed air at 90 psi, it delivers 0.75 horsepower and 600 RPM through a 1/2 inch keyed chuck, producing up to 255 inch-pounds of torque. At 4.9 pounds and 11.1 inches overall length, it is compact enough for confined-space applications without sacrificing power. Machinists, millwrights, pipefitters, and maintenance technicians working in industrial and manufacturing environments rely on this tool for drilling metal, fastening, and precision hole work where a standard inline drill cannot reach.

The right angle head design makes this drill well suited for tight-clearance drilling in structural steel, framing, equipment enclosures, and mechanical assemblies. The 1/2 inch keyed chuck accommodates a wide range of standard drill bits and accessories. Air-powered operation makes it a reliable choice in environments where electric tools present a hazard or where sustained duty cycles exceed what a cordless platform can support. This drill is used across heavy industry, shipbuilding, fabrication shops, and commercial construction where professional-grade pneumatic tooling is standard.

Installation Notes

This tool is installed and serviced by qualified industrial mechanics, millwrights, or pneumatic tool technicians. Before connecting to an air supply, verify the line pressure is regulated to 90 psi and that an inline oiler and filter-regulator are present to protect internal components. Use thread sealant rated for pneumatic fittings on the 1/4 inch NPT inlet connection. Disconnect the air supply completely before changing chuck accessories or performing any maintenance.
