Ingersoll Rand G3H150PG4M Air Angle Die Grinder | 1.35 HP | 15,000 RPM | 6 (mm) Collet | Rear Exhaust

For deburring machined components, removing casting imperfections, and cleaning welded metal surfaces, the Ingersoll Rand G3H150PG4M Air Die Grinder provides pneumatic grinding power in a straight horizontal configuration. Part of the G3 Series, this grinder features a 1.35 HP (1.0 kW) vane motor and a 15,000 RPM maximum free speed for industrial material removal and surface preparation. Its 6 mm collet accommodates compatible metric-shank carbide burrs, mounted grinding points, and other approved abrasives. Unlike angle-head die grinders, the horizontal configuration positions the grinding accessory along the tool's longitudinal axis, supporting direct access to metal edges, casting features, and recessed surfaces where straight-line tool positioning is practical.

The G3H150PG4M features a 9-inch (230 mm) overall length and weighs approximately 2.3 lbs (1.05 kg), combining substantial pneumatic motor power with manageable dimensions for repeated grinding operations. Its lightweight composite housing and ergonomically shaped body provide a comfortable gripping surface, while the G3 Series vibration-dampening design helps limit vibration transmitted to the operator. The manufacturer specifies 15.6 L/s maximum air consumption, a 3/8-inch air inlet, and a 1/2-inch (13 mm) minimum hose size, making appropriate compressed air delivery essential for consistent operation. This combination suits fabrication shops, metal processing facilities, equipment manufacturers, and industrial maintenance departments performing recurring grinding and finishing tasks.

FAQs:

• Q: Is the Ingersoll Rand G3H150PG4M an angle grinder or a straight die grinder?

  A: The G3H150PG4M is a straight horizontal die grinder, not an angle-head model. Its grinding accessory aligns with the length of the tool body. For applications requiring the accessory to operate at an angle to the motor housing, a suitable G3 Series angle configuration should be considered.

• Q: What grinding accessories can be used with the G3H150PG4M?

  A: This grinder features a 6 mm collet for compatible metric-shank grinding accessories, including suitable carbide burrs and mounted grinding points. Every accessory must be approved for the intended grinding application and rated for at least 15,000 RPM. Follow the accessory manufacturer's requirements for permitted diameter, shank insertion, and overhang.

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

  A: Both models provide 1.0 kW rated power and use a 6 mm collet. The G3H150PG4M operates at 15,000 RPM with maximum air consumption of 15.6 L/s, while the G3H180PG4M operates at 18,000 RPM with maximum air consumption of 26 L/s. Consider the required accessory speed, material removal task, and available compressed air capacity when selecting between them.

• Q: What compressed air supply does the G3H150PG4M require?

  A: The manufacturer lists maximum air consumption of 15.6 L/s, approximately 33.1 CFM, with a 3/8-inch NPT air inlet and minimum 1/2-inch (13 mm) hose size. Select a compressor and air distribution system capable of meeting the grinder's airflow needs at the recommended operating pressure. Account for other pneumatic equipment sharing the air supply.

• Q: Can this die grinder be used for weld cleanup and casting deburring?

  A: Yes. The G3 Series supports industrial material removal using compatible burrs, grinding points, and coated abrasives. The G3H150PG4M can be used for suitable weld cleanup, casting deburring, and component finishing tasks, provided the selected accessory meets the tool's mounting and operating speed requirements.
