Chicago Pneumatic 8941097920 Air Drill 3/8 in Keyless

Product Description

The CHICAGO PNEUMATIC 8941097920 is a reversible pneumatic drill built for trade and production environments where consistent rotational speed and compact handling matter. Driven by compressed air at 90 psi, it delivers 2,100 RPM and 0.5 horsepower through a 3/8 inch keyless chuck that allows fast bit changes without a chuck key. At 2.4 pounds, the pistol grip body stays maneuverable during overhead work, confined-space fastening, or repetitive drilling tasks on the shop floor. A reversible motor direction makes it suitable for both driving and extraction applications. The 1/4 inch inlet connects to standard shop air lines, and an air hose is included in the package.

This drill fits production assembly, automotive service, HVAC rough-in, light fabrication, and general mechanical maintenance applications. The pistol grip handle suits right-angle access tasks and sustained drilling runs where a straight-body tool would be awkward. The keyless chuck accepts standard fractional and metric twist drill bits within the 3/8 inch capacity range. It is appropriate for use by mechanics, pipefitters, HVAC technicians, and general tradespeople who maintain a shop air supply at or near 90 psi.

Compatibility

Designed for use with standard 1/4 inch NPT shop air lines operating at 90 psi. Accepts 3/8 inch capacity twist drill bits, hex-shank bits, and other standard tooling within the chuck range.

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 line pressure does not exceed the rated operating pressure and that the air supply is fitted with a filter-regulator-lubricator to protect internal components. Depressurize and disconnect the air line before changing bits or performing any maintenance. Follow applicable workplace safety and compressed-air codes when setting up the air supply circuit.
