Ingersoll Rand G3H180PG4M Air Angle Die Grinder | 1.35 HP | 18,000 RPM | 1/4" Collet | Rear Exhaust

For production deburring, weld cleanup, and metal surface preparation, the Ingersoll Rand G3H180PG4M Air Die Grinder delivers high-speed pneumatic grinding performance for fabrication shops, metalworking facilities, and industrial maintenance operations. 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 removing burrs, smoothing rough castings, and finishing machined components with compatible grinding accessories. Its 6 mm collet accommodates appropriately sized metric-shank carbide burrs and mounted abrasives. The straight horizontal configuration positions the grinding accessory along the tool's main axis, allowing operators to approach metal edges, recessed surfaces, and component features directly. This configuration is particularly useful when straight-line access is available and a compact grinding head is preferred over an angled arrangement.

The G3H180PG4M combines substantial pneumatic power with a 9-inch (230 mm) overall length and a 2.3 lb (1.05 kg) weight, making it suitable for repetitive grinding and finishing tasks without the size of a larger wheel grinder. Its lightweight composite housing and ergonomically shaped body provide a comfortable gripping surface during operation. The G3 Series incorporates vibration-dampening features to help reduce vibration transmitted through the tool, supporting controlled handling during material removal. With a 3/8-inch air inlet, 1/2-inch (13 mm) minimum hose size, and 26 L/s maximum air consumption, this grinder requires an adequately sized compressed air system. Its combination of motor power, high rotational speed, and straight-body access makes it a practical choice for recurring industrial deburring and metal finishing operations.

FAQs:

• Q: Is the Ingersoll Rand G3H180PG4M an angle die grinder or a straight die grinder?

  A: The G3H180PG4M is a straight horizontal die grinder. Its grinding accessory aligns with the tool's longitudinal axis rather than operating through an angled grinding head. This configuration is suited to applications where direct access to the workpiece is available.

• Q: Does the G3H180PG4M use a 1/4-inch collet or a 6 mm collet?

  A: Ingersoll Rand specifies a 6 mm collet for model G3H180PG4M. The related G3H180RG4 uses a 1/4-inch collet. These sizes are different and should not be treated as interchangeable. Select accessories with shanks that match the installed collet.

• Q: How does the G3H180PG4M compare with the G3H150PG4M?

  A: Both models deliver 1.35 HP rated power and use a 6 mm collet in a straight horizontal configuration. The G3H180PG4M operates at 18,000 RPM with maximum air consumption of 26 L/s, while the G3H150PG4M operates at 15,000 RPM with maximum air consumption of 15.6 L/s according to the manufacturer's metric specification table. Choose according to grinding speed, accessory suitability, and available compressed air capacity.

• Q: What compressed air system is needed for the G3H180PG4M?

  A: The manufacturer specifies maximum air consumption of 26 L/s, approximately 55.1 CFM, a 3/8-inch air inlet, and a minimum 13 mm hose diameter. Use a compressor and compressed air distribution system capable of delivering the required airflow at the manufacturer's recommended operating pressure.

• Q: Can this die grinder be used for deburring and removing weld imperfections?

  A: Yes. The G3 Series is suitable for industrial material removal with carbide burrs, grinding points, and appropriately selected abrasives. The G3H180PG4M can handle deburring, suitable weld cleanup, and rough casting preparation when the selected accessory is compatible with the tool and rated for at least 18,000 RPM.
