Chicago Pneumatic 6151600150 Straight Air Die Grinder

Product Description

The CHICAGO PNEUMATIC 6151600150 is a straight air die grinder designed for precision grinding, deburring, and surface finishing in professional trade environments. Powered by compressed air at 90 psi, the tool delivers 0.4 HP and spins at up to 25,000 RPM through a 1/4 inch collet. The lever-style throttle gives the operator direct speed control during use. Rear exhaust routing directs spent air away from the workpiece and the operator's hands. At 0.9 pounds, this grinder is suited for extended single-hand use in tight spaces. It is installed and operated by machinists, auto body techs, metal fabricators, and maintenance mechanics.

This straight air die grinder fits typical shop and field applications where a rotary cutting or grinding tool must reach confined areas on metal, composite, or weld joint surfaces. Common use cases include weld preparation, port work, gasket surface cleanup, and casting flash removal. The tool connects to a standard shop air line and requires a consistent supply delivering at least 90 psi to maintain rated speed. Air consumption at full load is approximately 19.07 CFM, so the supply compressor and line size should be matched accordingly before use.

Key Features

• 25,000 RPM rated spindle speed for aggressive material removal or fine finishing work
• 0.4 HP air motor operates at 90 psi supply pressure
• 1/4 inch collet accepts standard die grinder bits, carbide burrs, and mounted points
• Lever throttle allows variable speed control during operation
• Rear exhaust design routes air discharge away from the work surface
• Lightweight at 0.9 pounds for reduced operator fatigue in extended use

Compatibility

Designed as an OEM-specification straight die grinder compatible with standard 1/4 inch shank rotary tooling and conventional shop air supply systems operating at 90 psi.

Installation Notes

Installation and setup should be performed by qualified personnel familiar with pneumatic tool safety. Before attaching or changing any collet tooling, shut off the air supply and bleed residual pressure from the line. Verify the air supply line, fittings, and hose rating are appropriate for the operating pressure before connecting. Inspect the collet and collet nut for wear before each use and confirm the accessory is rated for spindle speeds at or above 25,000 RPM.
