Ingersoll Rand G3X150PG4M Air Angle Die Grinder | 1.35 HP | 15,000 RPM | 1/4" Collet | Rear Exhaust

Reaching welds, casting features, and machined surfaces inside deep assemblies calls for a grinder with more access than a conventional short-body tool. The Ingersoll Rand G3X150PG4M Extended Air Die Grinder combines a 1.35 HP (1.0 kW) vane motor with a 15,000 RPM maximum free speed for industrial deburring, localized material removal, and metal finishing. Part of the G3 Series, this pneumatic grinder features an extended horizontal configuration that positions the grinding accessory along the tool's axis while providing additional reach into recessed work areas. Its 6 mm collet grips compatible metric-shank carbide burrs and mounted grinding points. This combination makes the G3X150PG4M suitable for fabrication, casting cleanup, and machinery maintenance tasks where both grinding power and workpiece accessibility matter.

The G3X150PG4M measures 14.1 inches (359 mm) in overall length and weighs approximately 3.7 lbs (1.7 kg), allowing operators to access deeper grinding locations without relying on unsupported accessory overhang. Its lightweight composite housing and ergonomically shaped body provide a practical gripping surface for repeated grinding operations. The G3 Series incorporates vibration-dampening features, with this model carrying a manufacturer-listed 3.8 m/s² vibration level. A 3/8-inch air inlet and 13 mm (1/2-inch) minimum hose size support the compressed air connection, while 15.6 L/s maximum air consumption is an important consideration when sizing the air supply. The extended configuration is particularly useful for reaching internal metal surfaces, equipment frames, and recessed components during fabrication and repair.

Features:

• Extended horizontal configuration provides additional reach for accessing recessed surfaces, internal casting features, and metal components behind surrounding structures.
• Powerful vane motor delivers 1.0 kW of rated power for industrial grinding, deburring, and localized material removal.
• 15,000 RPM maximum free speed supports grinding with compatible carbide burrs and mounted abrasive accessories.
• 6 mm collet accepts correctly sized metric-shank grinding accessories for detailed edge finishing and component cleanup.
• Lightweight composite housing provides a manageable tool body for repetitive metal finishing in production and maintenance environments.
• Ergonomically shaped body offers a comfortable gripping surface for positioning the extended grinder during operation.
• G3 Series vibration dampening helps manage vibration transmission during grinding and surface preparation.
• Extended body allows deeper tool access while retaining a straight grinding configuration for accessories mounted along the tool's longitudinal axis.

Applications:

• Foundry and casting operations: Removing burrs, cleaning internal casting features, and grinding recessed metal surfaces where a shorter tool cannot reach comfortably.
• Metal fabrication and welding: Cleaning weld irregularities inside fabricated structures, smoothing difficult-to-reach edges, and preparing recessed metal joints for finishing.
• Heavy machinery manufacturing: Deburring equipment frames, cleaning internal mechanical features, and finishing fabricated components before assembly.
• Tool and die workshops: Removing burrs from deep cavities, refining accessible machined features, and performing localized grinding with approved carbide burrs.
• Railroad and transportation maintenance: Cleaning recessed metal components and preparing machinery parts during equipment servicing and repair.
• Industrial maintenance and MRO: Grinding internal surfaces, removing minor metal imperfections, and refurbishing components where extended tool reach improves access.

FAQs:

• Q: Is the Ingersoll Rand G3X150PG4M an angle die grinder or an extended straight die grinder?

  A: The G3X150PG4M is an extended horizontal die grinder. Its grinding accessory aligns with the tool's main axis rather than operating through an angle head. The extended body provides additional access to recessed work areas where a shorter straight grinder may be difficult to position.

• Q: What grinding accessories can be used with the G3X150PG4M?

  A: The manufacturer specifies 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 application and rated for at least 15,000 RPM. Follow the accessory manufacturer's requirements for shank engagement, permitted diameter, and maximum overhang.

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

  A: Both models feature 1.35 HP rated power, a 6 mm collet, and the same 14.1-inch extended horizontal configuration. The G3X150PG4M operates at 15,000 RPM with maximum air consumption of 15.6 L/s, while the G3X180PG4M operates at 18,000 RPM with maximum air consumption of 26 L/s. Selection depends on the required accessory speed, grinding task, and compressed air capacity.

• Q: What air compressor requirements should be considered for the G3X150PG4M?

  A: Ingersoll Rand lists maximum air consumption at 15.6 L/s, approximately 33.1 CFM. The grinder uses a 3/8-inch air inlet and requires a minimum 13 mm air hose. The compressor and air distribution system should supply sufficient airflow at the recommended operating pressure, taking other pneumatic tools on the same system into account.

• Q: Can the G3X150PG4M be used for grinding inside metal assemblies?

  A: Yes. The extended horizontal configuration makes this model suitable for reaching accessible internal metal features, recessed castings, and fabricated structures. Confirm that the tool and mounted accessory have adequate clearance for safe operation, and use only approved abrasives with the correct speed rating.
