Ingersoll Rand G1A200PS4 Angle Air Die Grinder | 0.4 HP | 20,000 RPM | 1/4" - 20 Spindle | Piped Away Exhaust

For metal finishing operations that require an angled tool head and a threaded accessory connection, the Ingersoll Rand G1A200PS4 Angle Air Die Grinder delivers compact pneumatic grinding performance for fabrication, machinery maintenance, and manufacturing environments. Part of the G1 Series, this grinder features a 0.4 HP (0.30 kW) rated motor and a 20,000 RPM maximum free speed for deburring, light material removal, weld cleanup, and rough casting preparation. Its 1/4"-20 threaded spindle provides a screw-threaded mounting connection for compatible grinding accessories, distinguishing it from collet-equipped die grinders that grip smooth accessory shanks. The piped-away exhaust configuration allows discharged compressed air to be routed away from the immediate work area, while the angle-head arrangement improves access around surrounding components and restricted metal surfaces.

Measuring 5.98 inches (152 mm) in overall length and weighing 1.10 lbs (0.50 kg), the G1A200PS4 offers a compact configuration for repeated grinding operations where tool positioning is important. Its ergonomically shaped D-style grip provides a comfortable holding surface, while the G1 Series construction is built to withstand repeated drops, exposure to harsh chemicals, and challenging working conditions. One-nut access for motor servicing simplifies maintenance access when internal components require attention. The grinder consumes 25 CFM (708 L/min) of compressed air at load and features a 1/4-inch air inlet with an 8 mm minimum hose size. Its manufacturer-listed vibration level below 2.5 m/s² provides an additional consideration when evaluating the tool for repetitive industrial finishing work.

• 0.4 HP (0.30 kW) rated power supports light material removal, deburring, rough casting cleanup, and localized weld finishing.
• 20,000 RPM maximum free speed provides high-speed rotation for compatible grinding accessories rated for the tool's operating speed.
• 1/4"-20 threaded spindle accommodates appropriately rated accessories with a compatible threaded mounting arrangement.
• Piped-away exhaust allows discharged compressed air to be directed away from the immediate grinding position through suitable exhaust routing.
• Compact, lightweight construction and ergonomically shaped D-style grip support controlled handling during repeated finishing operations.
• G1 Series construction is made to withstand repeated drops, harsh chemical exposure, and tough industrial environments.
• One-nut access for motor servicing simplifies access to internal motor components during inspection and maintenance.

Applications:

• Metal fabrication and welding: Removing minor weld irregularities, smoothing metal edges, and preparing accessible surfaces for additional finishing.
• Foundry and casting operations: Cleaning casting flash, removing burrs, and refining localized casting surfaces with suitable spindle-mounted accessories.
• Tool and die maintenance: Finishing machined components and removing sharp edges from metal profiles where an angle-head grinder improves access.
• Heavy machinery and railroad maintenance: Preparing metal components, cleaning accessible mechanical parts, and performing localized grinding during repairs.
• Automotive body and repair workshops: Cleaning suitable metal surfaces, smoothing fabricated edges, and preparing components for subsequent repair operations.
• Industrial manufacturing and MRO: Deburring fabricated parts, performing light surface grinding, and maintaining mechanical equipment in restricted working areas.

FAQs:

• Q: What grinding accessories fit the Ingersoll Rand G1A200PS4?

  A: The G1A200PS4 features a 1/4"-20 threaded spindle for accessories with an approved, compatible mounting arrangement. This is not a conventional collet that grips smooth accessory shanks. Confirm the accessory's thread, mounting requirements, maximum permitted dimensions, and minimum speed rating of 20,000 RPM before installation.

• Q: What is the difference between the G1A200PS4 and G1A120PS4?

  A: Both grinders provide 0.4 HP rated power, a 1/4"-20 threaded spindle, and piped-away exhaust. The G1A200PS4 operates at 20,000 RPM and consumes 25 CFM at load, while the G1A120PS4 operates at 12,000 RPM and consumes 18.96 CFM at load. Choose according to the intended grinding operation, accessory speed requirements, and available compressed air capacity.

• Q: How is the G1A200PS4 different from the G1A200PG4M?

  A: Both models have 0.4 HP rated power, 20,000 RPM maximum free speed, an angle-head configuration, and piped-away exhaust. The G1A200PS4 uses a 1/4"-20 threaded spindle, while the G1A200PG4M uses a 6 mm collet. These mounting systems require different grinding accessory configurations.

• Q: What compressor and air hose requirements should be considered?

  A: Ingersoll Rand specifies 25 CFM (708 L/min) air consumption at load, a 1/4-inch air inlet, and an 8 mm minimum hose size. Ensure the compressed air system can deliver sufficient airflow at the manufacturer's recommended operating pressure, including when other pneumatic equipment shares the supply.

• Q: Does the piped-away exhaust system remove grinding dust?

  A: No. Piped-away exhaust provides a means of routing discharged compressed air away from the grinding area. It is not a dust extraction system. Appropriate ventilation, dust collection, and personal protective equipment remain necessary for the work being performed.
