Chicago Pneumatic 6151607010 Air Angle Grinder 4 in 1 Hp

Product Description

The CHICAGO PNEUMATIC 6151607010 is a pneumatic angle grinder built for demanding grinding, cutting, and surface preparation tasks in industrial and trade environments. Powered by compressed air at 90 psi, it spins a 4-inch wheel at 13,500 RPM and delivers 1 horsepower through a durable bevel gear drive. The 3/8-24 spindle accepts Type 1 and Type 27 wheels, and the side exhaust keeps spent air away from the work surface. Air connects through a 1/4-inch NPT inlet, with a free air consumption rate of 8.2 CFM at rated pressure. Licensed contractors and industrial maintenance techs are the primary installers and operators.

This grinder is suited for metalworking, weld dressing, deburring, and surface prep in fabrication shops, mechanical rooms, and job-site settings. The safety lever with trigger lock prevents accidental startup, making it appropriate for sustained grinding passes. The robust machined steel housing holds up in environments where tools take repeated impact and exposure to metal swarf and coolant. Typical applications include structural steel work, pipe fitting, and maintenance operations where a compact 4-inch pneumatic grinder is preferred over a larger electric unit.

Key Features

• 13,500 RPM free speed with 1 HP output through a durable bevel gear drive
• Accepts Type 1 and Type 27 wheels on a 3/8-24 spindle
• Safety lever with trigger lock prevents unintended operation
• Side exhaust directs air away from operator and work surface
• Robust machined steel housing resists wear in heavy-use environments
• 1/4-inch NPT air inlet fits standard shop air fittings

Compatibility

Designed for use with standard 4-inch Type 1 and Type 27 grinding and cutting wheels mounted on a 3/8-24 threaded spindle. Requires a compressed air supply capable of delivering 90 psi and at least 8.2 CFM at the tool inlet.

Installation Notes

Installation and operation should be performed by qualified personnel familiar with pneumatic tool safety practices. Before mounting or changing wheels, disconnect the air supply and verify zero pressure at the inlet. Ensure the air line is sized to maintain adequate CFM at the tool under load, as undersized lines reduce performance and can cause stall. Follow ANSI B7.1 wheel mounting guidelines and always use the correct wheel guard for the wheel type installed.
