Ingersoll Rand G3A120PG4M Air Angle Die Grinder | 1.35 HP | 12,000 RPM | 6 (mm) Collet | Rear Exhaust

For deburring metal components, cleaning welded joints, and grinding surfaces around obstructions, the Ingersoll Rand G3A120PG4M Air Angle Die Grinder combines powerful pneumatic operation with an angled grinding head for improved workpiece access. Part of the G3 Series, this grinder delivers 1.35 HP (1.0 kW) rated power and a 12,000 RPM maximum free speed for removing burrs, smoothing casting imperfections, and performing localized material removal. Its 6 mm collet securely grips compatible metric-shank carbide burrs and mounted abrasives, while the angle-head configuration positions the grinding accessory at approximately 90 degrees to the tool body. This arrangement helps operators reach metal surfaces around brackets, machinery components, and fabricated structures where a straight die grinder may be difficult to position.

The G3A120PG4M features a 9.5-inch (241 mm) overall length and weighs 4.2 lbs (1.9 kg), providing a practical configuration for repeated grinding and finishing work. Its lightweight composite housing and ergonomically shaped body offer a comfortable gripping surface, while the G3 Series vibration-dampening design helps limit vibration transmitted through the tool during operation. The grinder uses a 3/8-inch NPT air inlet and requires a 1/2-inch (13 mm) minimum hose size to support adequate compressed air delivery. With 26 L/s maximum air consumption, equivalent to approximately 55.1 CFM, this model is suited to industrial compressed air systems capable of supporting its operating requirements. Its combination of motor power, angle-head access, and metric collet compatibility makes it useful for metal fabrication, manufacturing, and industrial maintenance operations.

FAQs:

• Q: What grinding accessories are compatible with the Ingersoll Rand G3A120PG4M?

  A: The G3A120PG4M uses a 6 mm collet for compatible metric-shank grinding accessories, including suitable carbide burrs and mounted grinding points. Accessories must be approved for the intended grinding application and rated for at least 12,000 RPM. Follow the accessory manufacturer's limits for shank insertion, diameter, and permitted overhang.

• Q: What is the difference between the G3A120PG4M and G3A120RG4?

  A: Both models belong to the G3 Series and operate at 12,000 RPM with the same nominal motor power. The G3A120PG4M uses a 6 mm collet, while the G3A120RG4 uses a 1/4-inch collet. Their collet dimensions differ, so select the model that matches the accessory shank size required for your application.

• Q: What advantage does an angle die grinder provide over a straight die grinder?

  A: An angle die grinder positions the accessory perpendicular to the main tool body, helping operators work around obstructions and access surfaces that are difficult to approach directly. Straight die grinders position the accessory along the tool's axis and may be more suitable for other grinding locations. Choose based on the workpiece geometry and available clearance.

• Q: How much compressed air does the G3A120PG4M require?

  A: Ingersoll Rand specifies maximum air consumption of 26 L/s, approximately 55.1 CFM, along with a 3/8-inch NPT air inlet and a minimum 1/2-inch (13 mm) air hose. The compressor and air distribution system must supply sufficient airflow at the manufacturer's recommended operating pressure, particularly during extended grinding operations.

• Q: Can the G3A120PG4M be used for weld cleanup and casting deburring?

  A: Yes. The G3 Series is intended for industrial material removal using compatible burrs, grinding points, and coated abrasives. This model can perform suitable weld cleanup, casting deburring, and edge finishing tasks when the selected accessory is matched to the material, tool speed, and mounting configuration.
