Ingersoll Rand G1A120PG4M Angle Air Die Grinder | 0.4 HP | 12,000 RPM | 6 (mm) Collet | Piped Away Exhaust

For metal finishing tasks that require access around obstructions and controlled grinding at moderate rotational speed, the Ingersoll Rand G1A120PG4M Angle Air Die Grinder provides a compact pneumatic solution for fabrication, manufacturing, and equipment maintenance. Part of the G1 Series, this angle die grinder features a 0.4 HP (0.30 kW) rated motor and a 12,000 RPM maximum free speed for light material removal, deburring, rough casting cleanup, and localized weld finishing. Its 6 mm collet accommodates compatible metric-shank grinding accessories, while the piped-away exhaust configuration allows discharged compressed air to be routed away from the immediate work area. The angle-head design positions the grinding accessory at approximately 90 degrees to the tool body, helping operators work along metal edges, around structural components, and inside assemblies where a straight grinder may be difficult to position.

The G1A120PG4M measures 5.98 inches (152 mm) in overall length and weighs 1.10 lbs (0.50 kg), making it convenient for localized grinding where tool clearance and positioning matter. Its ergonomically shaped D-style grip provides a comfortable handling surface during repetitive finishing operations. G1 Series construction is built to withstand repeated drops, harsh chemicals, and challenging industrial conditions, while one-nut access for motor servicing simplifies access during maintenance. With 18.96 CFM (537 L/min) air consumption at load, a 1/4-inch air inlet, and a 10 mm minimum hose size, this model can be matched to a compressed air system capable of supporting its specified airflow requirements.

Applications:

• Metal fabrication and welding: Removing minor weld irregularities, cleaning fabricated edges, and finishing metal surfaces near surrounding components.
• Foundry and casting operations: Removing casting flash, deburring accessible casting features, and cleaning localized surface imperfections.
• Tool and die maintenance: Refining machined profiles, removing burrs, and performing detailed material removal with compatible grinding accessories.
• Automotive and transportation repair: Cleaning suitable metal components, smoothing sharp edges, and performing localized grinding during mechanical servicing.
• Industrial machinery manufacturing: Preparing component surfaces, deburring fabricated parts, and working around obstructed sections of mechanical assemblies.
• Maintenance and MRO operations: Performing light grinding, surface preparation, and component refurbishment where an angled grinding head improves access.

FAQs:

• Q: What grinding accessories are compatible with the Ingersoll Rand G1A120PG4M?

  A: The grinder features a 6 mm collet for compatible metric-shank grinding accessories, including appropriately rated carbide burrs and mounted grinding points. Accessories must be approved for angle die grinder operation and rated for at least 12,000 RPM. Follow the accessory manufacturer's requirements for permitted diameter, shank engagement, and overhang.

• Q: What is the difference between the G1A120PG4M and G1A120PS4?

  A: Both models deliver 0.4 HP rated power, operate at 12,000 RPM, and feature piped-away exhaust. The G1A120PG4M uses a 6 mm collet for smooth-shank grinding accessories, while the G1A120PS4 features a 1/4"-20 threaded spindle. Their accessory mounting systems are different, so selection should be based on the grinding accessories required.

• Q: How does the G1A120PG4M compare with the G1A200PG4M?

  A: Both grinders provide 0.4 HP rated power, a 6 mm collet, and piped-away exhaust. The G1A120PG4M operates at 12,000 RPM with 18.96 CFM air consumption at load, while the G1A200PG4M operates at 20,000 RPM with 25 CFM at load. Choose according to accessory speed requirements, the grinding process, and available compressed air capacity.

• Q: What compressed air supply does the G1A120PG4M require?

  A: Ingersoll Rand specifies 18.96 CFM (537 L/min) air consumption at load, a 1/4-inch air inlet, and a 10 mm minimum hose size. Ensure the compressor and compressed air distribution system can provide the required airflow at the manufacturer's recommended operating pressure, particularly during repeated grinding operations.

• Q: Does piped-away exhaust collect grinding dust?

  A: No. Piped-away exhaust allows compressed air discharged from the tool to be directed away from the immediate work area. It does not collect metal particles or abrasive dust. Appropriate workplace ventilation, dust extraction, and personal protective equipment remain necessary.
