Chicago Pneumatic 8941074120 Air Die Grinder 0.56 Hp

Product Description

The CHICAGO PNEUMATIC 8941074120 is a straight-style pneumatic die grinder built for grinding, deburring, porting, and surface preparation in fabrication and maintenance environments. It runs at 22000 RPM on 0.56 horsepower, powered by a 1/4 inch NPT air inlet at 90 psi and 3.6 CFM. The composite housing keeps weight manageable at 3.31 pounds over a 13-inch overall length, and the comfort grip handle reduces fatigue during extended use. Rear exhaust directs air away from the work surface and the operator. Licensed trades and industrial mechanics routinely reach for this tool when a right-angle or rotary grinder is too large for the task.

This die grinder suits metal fabrication shops, maintenance and repair operations, and field service work where a compact, inline air tool is required. The 1/4 inch collet is standard for mounted points, carbide burrs, and abrasive bits used in deburring castings, weld cleanup, and port grinding on engine components. The included 6mm collet expands bit compatibility for metric tooling. It is appropriate for both light industrial and heavy-duty trade use wherever a regulated compressed-air supply is available.

Key Features

• 22000 RPM operating speed with a range of 18000 to 24999 RPM for controlled material removal
• 0.56 HP motor delivers consistent power for burr work, grinding, and surface prep
• 1/4 inch collet and included 6mm collet for broad bit compatibility
• Rear exhaust keeps airflow away from the work area and operator
• Composite housing reduces overall tool weight to 3.31 pounds
• Comfort grip handle designed for extended-use fatigue reduction
• Straight inline style fits confined workspaces where angled tools cannot reach

Compatibility

Designed for use with standard 1/4 inch shank and 6mm shank rotary accessories including carbide burrs, mounted grinding stones, and abrasive bits. Requires a compressed-air supply capable of sustaining 90 psi and at least 3.6 CFM at the tool inlet.

Installation Notes

Installation and operation should be performed by a qualified pneumatic tool technician or experienced tradesperson. Before connecting to an air supply, verify the line pressure does not exceed the rated 90 psi and that an inline oiler or lubricator is present to extend tool service life. Disconnect the air supply before changing collets or accessories, and use the included spanner wrench for collet changes. Always wear appropriate eye protection and hearing protection given the 91.4 dB rated noise level during operation.
