Chicago Pneumatic 8941008790 Air Drill 3/8 in Keyed Chuck

Product Description

The CHICAGO PNEUMATIC 8941008790 is a reversible pneumatic air drill built for professional trade use in assembly, fabrication, and maintenance applications. It accepts a 3/8 inch keyed chuck and delivers 2,000 RPM at 90 psi, powered by a 0.3 HP air motor. The inline and right angle handle configuration gives technicians flexibility in tight-access drilling scenarios. Weighing 2.6 pounds and measuring 8.58 inches in overall length, this drill balances control and reach without excessive fatigue during extended use. A 1/4 inch inlet connects to standard shop air lines, and an air hose is included in the package.

This drill suits residential and light commercial maintenance environments where pneumatic tools are preferred over electric for consistent torque delivery and reduced motor heat buildup. The reversible function makes it practical for both driving and removing fasteners in addition to standard drilling tasks. Typical installation scenarios include mechanical rooms, production floor assembly, and service bay work where a compact, low-weight pneumatic drill is needed for repetitive or precision drilling operations.

Installation Notes

Installation and operation should be performed by a qualified technician familiar with pneumatic tool safety practices. Before connecting to an air supply, verify the compressor output does not exceed the tool's rated 90 psi operating pressure. Ensure the air line is depressurized before changing chuck accessories or performing any maintenance on the tool. Follow applicable OSHA and shop-safety guidelines for personal protective equipment when operating pneumatic drilling equipment.
