Ingersoll Rand G3A120PP95AV Air Angle Grinder | 1.35 HP | 12,000 RPM | M14 Thread | Rear Exhaust

Built for weld grinding, metal fabrication, and surface preparation, the Ingersoll Rand G3A120PP95AV Air Angle Grinder delivers the power and wheel speed needed for material removal in production and maintenance environments. Part of the G3 Series, this pneumatic angle grinder features a 1.35 HP (1.0 kW) vane motor and a 12,000 RPM maximum free speed for grinding welded joints, smoothing fabricated edges, and preparing metal surfaces. Its 5-inch (125 mm) Type 27 wheel capacity accommodates approved depressed-center grinding wheels, while the M14 threaded spindle provides the metric mounting connection for compatible grinding accessories. The rear exhaust configuration directs discharged compressed air away from the operator, helping keep the immediate grinding position clear of tool exhaust airflow.

The G3A120PP95AV incorporates an auto-balancing system that reduces grinding vibration and helps increase abrasive disc life. A built-in lubricating wick improves lubrication of the bevel and pinion gear set, while an internal governor regulates motor operation to maintain effective grinding speed under load. Its lightweight composite housing helps insulate the operator's grip from cold compressed air, and the vibration-reduced side handle supports controlled tool handling during repeated grinding operations. An integral trigger safety lock helps prevent accidental startup. Measuring 9.63 inches (245 mm) in length and weighing approximately 4.7 lbs (2.1 kg), this grinder provides a practical balance of power, wheel capacity, and handling for fabrication shops, metalworking facilities, and industrial maintenance departments.

Applications:

• Metal fabrication and welding: Grinding weld beads, removing excess weld material, and smoothing fabricated metal joints before finishing.
• Structural steel fabrication: Preparing steel surfaces, refining component edges, and removing localized material from fabricated assemblies.
• Heavy equipment manufacturing: Grinding welded brackets, machinery frames, and suitable metal components during production.
• Foundry and metal processing: Smoothing rough casting surfaces, removing accessible imperfections, and preparing components for further machining or finishing.
• Shipbuilding and industrial construction: Cleaning welded steel assemblies and performing localized grinding on accessible metal structures.
• Industrial maintenance and MRO: Removing surface irregularities, refurbishing mechanical components, and preparing replacement parts during equipment repairs.

FAQs:

• Q: What grinding wheel size does the Ingersoll Rand G3A120PP95AV support?

  A: The manufacturer specifies a 5-inch (125 mm) Type 27 wheel with a maximum thickness of 1/4 inch (6 mm). Use only compatible wheels approved for the grinder's mounting arrangement and rated for at least 12,000 RPM. Follow the manufacturer's wheel guarding and installation instructions.

• Q: How does the auto-balancing system improve grinding performance?

  A: The auto-balancing system helps minimize vibration generated during grinding. Ingersoll Rand identifies reduced vibration and increased grinding disc life as benefits of this mechanism. Actual results depend on the wheel, workpiece, and operating conditions.

• Q: What compressed air supply is required for the G3A120PP95AV?

  A: The manufacturer specifies 55 CFM (26 L/s) air consumption at load, a 3/8-inch NPT air inlet, and a minimum 1/2-inch (13 mm) air hose. These specifications are stated at 90 PSI (6.2 bar). Select a compressor and air distribution system capable of delivering the necessary airflow during grinding.

• Q: What is the difference between the G3A120PP95AV and G3A100PP96AV?

  A: The G3A120PP95AV operates at 12,000 RPM with a 5-inch wheel capacity, while the G3A100PP96AV operates at 10,000 RPM with a 6-inch wheel capacity. Both provide 1.35 HP rated power and use an M14 spindle. Choose according to the required wheel size, accessory speed rating, and grinding application.

• Q: Does this grinder have a safety lock and rear exhaust?

  A: Yes. The G3A120PP95AV features an integral trigger safety lock that helps prevent accidental tool activation. Its rear exhaust directs compressed air away from the operator. A separate piped-away exhaust kit is also listed among the manufacturer's available accessories, but it should not be assumed to be included with the grinder.
