Ingersoll Rand 728JA1 Air Drill 3/8 in Keyed Chuck 0.5 Hp

Product Description

The INGERSOLL RAND 728JA1 is a pneumatic pistol-grip air drill built for production and maintenance applications where consistent rotational speed and compact handling matter. Powered by compressed air at 90 psi, this drill delivers 3,800 RPM and 30 in-lb of torque from a 0.5 HP motor. The 3/8 inch keyed chuck provides a secure bit hold suitable for repetitive drilling in metal, wood, and composite materials. At 3 pounds, it balances easily in one hand during sustained use. Automotive technicians, fabricators, millwrights, and general maintenance crews are the primary installers and operators of this tool.

This drill is suited for light-to-medium duty drilling tasks in shop, fleet maintenance, and light manufacturing environments. The pistol grip handle positions the operator naturally for drilling at bench height or into flat work surfaces. It is a non-reversible drill, making it appropriate for dedicated forward-rotation drilling operations rather than fastener removal. Air supply must be clean, dry, and regulated to the specified 90 psi operating pressure for consistent performance.

Key Features

• 3/8 inch keyed chuck for secure bit retention across a range of shank sizes
• 3,800 RPM free speed for efficient drilling in metal and other materials
• 0.5 HP pneumatic motor operating at 90 psi supply pressure
• Pistol grip handle for single-hand control and natural wrist alignment
• Compact overall length of 7 inches for use in tighter work areas
• Lightweight at 3 pounds, reducing operator fatigue during extended use

Compatibility

Designed for use with standard 1/4 inch NPT air fittings and compatible with air supply systems regulated to 90 psi. No specific model or system compatibility was stated in the product data.

Installation Notes

Connect the drill to a compressed air line using a 1/4 inch NPT fitting, and verify supply pressure is regulated to 90 psi before operation. Air consumption is 19 CFM, so the compressor and line sizing must support that demand without significant pressure drop. Ensure the air supply is filtered and lubricated per the tool manufacturer's maintenance guidelines to protect internal components. This is a non-reversible tool and should not be used for applications requiring reverse rotation.
