Ingersoll Rand 6AKST4 Air Drill 1/4 in Keyed Chuck 0.51 Hp

Product Description

The INGERSOLL RAND 6AKST4 is a pneumatic pistol-grip air drill designed for professional trade use in fabrication, automotive, and mechanical service environments. It runs at 3,100 RPM powered by a 0.51 hp air motor and accepts a 1/4 inch keyed chuck for secure bit retention across a wide range of drilling applications. At 2.19 pounds and 7 inches in overall length, this drill is compact enough for tight spaces while delivering the torque output needed for sustained production work. Rated at 90 psi inlet pressure and 20 CFM air consumption, it requires a properly sized compressor and air supply for consistent performance.

This drill suits residential and commercial construction, HVAC equipment assembly, automotive repair, and general mechanical work where a compact, lightweight pneumatic drill is preferred over a corded or cordless electric unit. The pistol grip handle provides a natural, controlled hold during drilling. Typical users include HVAC technicians, auto mechanics, machinists, and general maintenance professionals who rely on air tools for high-cycle tasks. The 1/4 inch keyed chuck accommodates standard twist bits and step drill bits used in sheet metal and light structural work.

Installation Notes

Installation and operation of this air drill should be performed by a qualified technician familiar with pneumatic tool safety practices. Before connecting or disconnecting the air supply, depressurize the line and verify the inlet pressure does not exceed the rated 90 psi to avoid tool damage or injury. Use a properly sized air hose and in-line filter-regulator-lubricator to protect the tool and maintain consistent performance. Consult applicable OSHA and ANSI pneumatic tool standards for personal protective equipment and safe operating procedures.
