Ingersoll Rand G3X180PG4M Air Angle Die Grinder | 1.35 HP | 18,000 RPM | 1/4" Collet | Rear Exhaust

For deburring recessed metal surfaces, cleaning internal casting features, and finishing welds in hard-to-reach locations, the Ingersoll Rand G3X180PG4M Extended Air Die Grinder provides powerful pneumatic grinding with an extended straight-body configuration. Part of the G3 Series, this grinder features a 1.35 HP (1.0 kW) vane motor and an 18,000 RPM maximum free speed for material removal using compatible carbide burrs, mounted grinding points, and other approved abrasives. Its 6 mm collet accommodates metric-shank grinding accessories, while the extended horizontal design provides additional reach for working inside fabricated structures, recessed machinery components, and deep casting cavities. Unlike angle-head grinders, this model positions the grinding accessory along the tool's longitudinal axis, supporting direct grinding access in restricted work areas.

The G3X180PG4M measures 14.1 inches (359 mm) in overall length and weighs approximately 3.7 lbs (1.7 kg), offering extended working reach for recurring grinding and finishing operations. Its lightweight composite housing and ergonomically shaped body provide a comfortable gripping surface during tool operation. The G3 Series incorporates vibration-dampening features, and this model has a manufacturer-reported vibration level below 2.5 m/s², a useful measurement when evaluating vibration exposure in repetitive metalworking applications. With a 3/8-inch air inlet, 1/2-inch (13 mm) minimum hose size, and 26 L/s maximum air consumption, the grinder requires a compressed air system capable of supporting its airflow requirements. These characteristics make it suitable for industrial fabrication, foundry maintenance, machinery manufacturing, and metal surface preparation.

• 18,000 RPM maximum free speed supports material removal with appropriately rated carbide burrs and mounted abrasive accessories.
• Extended horizontal configuration provides additional reach for grinding recessed surfaces, internal casting features, and metal components located behind surrounding structures.
• 6 mm collet accepts compatible metric-shank grinding accessories for localized material removal, edge finishing, and surface cleanup.
• Lightweight composite housing provides a manageable tool body for repetitive grinding operations in manufacturing and maintenance environments.
• Ergonomically shaped body provides a comfortable gripping surface for controlled handling and positioning of the extended grinder.
• G3 Series vibration-dampening construction helps reduce vibration transmission during grinding and finishing operations.
• Straight grinding configuration allows the accessory to remain aligned with the tool's main axis when accessing deeper workpiece locations.

Applications:

• Foundry and casting operations: Removing casting flash, cleaning internal casting features, and smoothing recessed metal surfaces where an extended grinder improves access.
• Metal fabrication and welding: Removing weld irregularities inside fabricated assemblies, finishing difficult-to-reach joints, and preparing recessed metal surfaces.
• Heavy machinery manufacturing: Deburring equipment frames, cleaning internal mechanical features, and finishing fabricated components before assembly.
• Tool and die maintenance: Removing burrs from deep cavities, refining accessible machined profiles, and performing localized material removal with compatible carbide burrs.
• Transportation and railroad maintenance: Cleaning recessed metal components, preparing machinery parts, and performing grinding operations during equipment repairs.
• Industrial maintenance and MRO: Removing sharp edges, preparing internal metal surfaces, and refurbishing mechanical components where additional tool reach is required.

FAQs:

• Q: Is the Ingersoll Rand G3X180PG4M an angle die grinder or an extended straight die grinder?

  A: The G3X180PG4M is an extended horizontal die grinder, not an angle-head model. Its grinding accessory operates along the tool's longitudinal axis. The extended body provides additional reach when working inside recessed metal assemblies and other locations where shorter grinders may be difficult to position.

• Q: Does the G3X180PG4M use a 1/4-inch collet or a 6 mm collet?

  A: Ingersoll Rand specifies a 6 mm collet for the G3X180PG4M. The related G3X180RG4 uses a 1/4-inch collet. These sizes are not interchangeable, so grinding accessories should have shanks matching the installed collet.

• Q: How does the G3X180PG4M compare with the G3X150PG4M?

  A: Both grinders provide 1.35 HP rated power, a 6 mm collet, and a 14.1-inch extended horizontal body. The G3X180PG4M operates at 18,000 RPM with maximum air consumption of 26 L/s, while the G3X150PG4M operates at 15,000 RPM with maximum air consumption of 15.6 L/s. Choose according to the grinding accessory's speed requirements and the compressed air capacity available.

• Q: What compressed air supply is required for the G3X180PG4M?

  A: The manufacturer specifies maximum air consumption of 26 L/s, approximately 55.1 CFM, with a 3/8-inch NPT air inlet and a minimum 13 mm air hose. The compressor and air distribution system must provide sufficient airflow at the recommended operating pressure, particularly during prolonged grinding operations.

• Q: Can this extended die grinder be used for grinding inside machinery and fabricated metal structures?

  A: Yes. Its extended horizontal configuration provides reach for suitable recessed grinding locations, internal casting features, and fabricated structures. Always confirm adequate clearance for the tool and accessory, and use grinding attachments approved for the application and rated for at least 18,000 RPM.
