Chicago Pneumatic 8941074100 Air Die Grinder 0.34 Hp

Product Description

The CHICAGO PNEUMATIC 8941074100 is a straight-style pneumatic die grinder designed for precision material removal, grinding, deburring, and surface finishing in trade and industrial environments. Running at 27000 RPM and drawing 2.7 CFM at 90 psi, this tool delivers 0.34 HP through a 1/4 inch collet. The composite housing keeps weight low at 1.87 pounds, and the comfort grip handle reduces fatigue during extended use. Exhaust exits from the rear of the tool, directing airflow away from the workpiece and the operator. Qualified machinists, pipefitters, fabricators, and maintenance technicians are the primary users.

This die grinder suits applications in metal fabrication shops, maintenance and repair operations, pipe fitting, and light-duty toolroom work. The rear exhaust configuration makes it practical in close-quarter grinding situations where front exhaust would blow debris toward the operator. The included 6mm collet expands accessory compatibility beyond standard 1/4 inch tooling. At 9.8 inches in overall length, the straight body fits comfortably in confined areas where angle grinders cannot reach.

Installation Notes

Installation and operation should be performed by qualified technicians familiar with pneumatic tool safety practices. Before connecting to an air supply, verify that line pressure does not exceed 90 psi and that an inline filter-regulator-lubricator is installed and serviced. Always fit collets and accessories per the manufacturer documentation included with the tool, and confirm the accessory RPM rating meets or exceeds the tool free speed of 27000 RPM before operation. Disconnect the air supply before changing collets or accessories.
