Chicago Pneumatic 8941074080 Air Die Grinder 0.34 Hp

Product Description

The CHICAGO PNEUMATIC 8941074080 is a straight-style air die grinder designed for material removal, porting, deburring, and surface finishing in professional shop and field environments. Powered by compressed air, it delivers 0.34 HP at a rated speed of 23000 RPM and requires 2.7 CFM at 90 psi to operate. The composite housing keeps weight to a manageable 1.87 pounds, and the comfort-grip handle reduces fatigue during extended use. Rear exhaust routing directs air away from the work surface and the operator. Licensed trades and industrial maintenance technicians are the primary installers and users of this tool.

This die grinder is suited for use in automotive, HVAC fabrication, metalworking, and general mechanical service environments. The 1/4 inch collet accepts standard burr bits, carbide bits, and mounted grinding points commonly found in trade and industrial settings. The included 6mm collet extends compatibility to metric accessories. It fits naturally into any compressed-air shop setup running a standard 1/4 inch NPT air supply line at 90 psi. Both light bench work and sustained production grinding are within its operating range.

Installation Notes

Installation and operation should be performed by qualified technicians familiar with pneumatic tool safety. Before connecting to an air supply, confirm the line pressure does not exceed the rated operating pressure of 90 psi and that an inline moisture separator or filter-regulator-lubricator unit is in the supply line. Always fit the collet and accessory bit securely with the included spanner before activating airflow. Wear appropriate PPE including eye protection and hearing protection, as the tool produces a rated sound level of 89.6 dB during operation.
