Chicago Pneumatic 8941074060 Air Die Grinder 0.34 Hp

Product Description

The CHICAGO PNEUMATIC 8941074060 is a straight-style air die grinder built for grinding, deburring, porting, and surface finishing in professional trade and industrial settings. Powered by compressed air at 90 psi and drawing 2.7 CFM, it delivers 23,000 RPM through a 1/4 inch collet. The composite housing keeps weight at 1.82 pounds, reducing fatigue during extended use. A comfort grip handle provides control during precision material removal. Rear exhaust directs air away from the workpiece and operator, keeping the work area clear. This tool is installed and operated by machinists, fabricators, automotive technicians, and general maintenance trades.

The 8941074060 is suited for die grinding, deburring, and finishing work in automotive, fabrication, and industrial maintenance applications. The angle-style head allows access to confined areas and tight workpiece geometries. At 6.4 inches in overall length, it fits comfortably in the hand for both overhead and detail work. The included 6mm collet expands compatibility with metric shanked accessories alongside standard 1/4 inch bits. Typical uses include weld cleanup, port matching, gasket surface preparation, and precision material removal on metal components.
