Ingersoll Rand G1H350PG4M Heavy Duty Straight Die Grinder | 0.4 HP | 35,000 RPM | 6 (mm) Collet | Piped Away Exhaust

When detailed metal finishing requires higher accessory speed and controlled tool positioning, the Ingersoll Rand G1H350PG4M Heavy Duty Straight Die Grinder provides a compact pneumatic solution for deburring, weld cleanup, and surface preparation. Part of the G1 Series, this straight die grinder combines 0.4 HP (0.3 kW) rated power with a 35,000 RPM maximum free speed for high-speed material removal using appropriately rated grinding accessories. Its 6 mm collet accommodates compatible metric-shank carbide burrs and mounted abrasives, while the piped-away exhaust configuration allows discharged compressed air to be routed away from the immediate work area. These characteristics make the G1H350PG4M particularly useful for cleaning machined edges, removing casting imperfections, and performing localized grinding where accessory speed and workpiece access are important.

The G1H350PG4M features a straight horizontal configuration that supports direct positioning of the grinding accessory against the workpiece. Its ergonomically shaped D-style grip provides a comfortable handling surface during repeated grinding operations, while the G1 Series construction is built to withstand repeated drops, harsh chemicals, and challenging industrial environments. A vibration level below 2.5 m/s² provides a useful reference for assessing tool vibration during operation, although actual exposure depends on the application and selected accessory. The grinder also incorporates one-nut access for motor servicing, simplifying maintenance access when inspection or repair is required. Its compact G1 Series design makes it suitable for fabrication shops, manufacturing facilities, and industrial maintenance work where detailed material removal is performed regularly.

Applications:

• Tool and die manufacturing: Removing burrs from machined profiles, refining component edges, and cleaning accessible metal features using compatible carbide burrs.
• Metal fabrication and welding: Smoothing localized weld irregularities, cleaning fabricated surfaces, and preparing metal edges for finishing.
• Foundry and casting operations: Removing casting flash, cleaning rough castings, and grinding small surface imperfections.
• Automotive and transportation manufacturing: Deburring machined components and finishing accessible metal surfaces during component production.
• Aerospace component manufacturing: Performing localized deburring and surface finishing where the selected tool and abrasive meet the applicable process requirements.
• Industrial maintenance and machinery repair: Removing sharp edges, cleaning mechanical components, and preparing metal surfaces during equipment refurbishment.

FAQs:

• Q: What types of grinding accessories can be used with the Ingersoll Rand G1H350PG4M?

  A: The grinder 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 application and rated for at least 35,000 RPM. Always follow the accessory manufacturer's limits for diameter, shank engagement, and overhang.

• Q: How does the G1H350PG4M compare with the G1H250PG4M?

  A: Both models provide 0.4 HP rated power, use a 6 mm collet, and feature piped-away exhaust. The G1H350PG4M operates at 35,000 RPM, while the G1H250PG4M operates at 25,000 RPM. The higher-speed model is suited to compatible accessories requiring faster rotation, while the lower-speed version may better match other grinding accessory requirements.

• Q: What is the advantage of piped-away exhaust on this die grinder?

  A: Piped-away exhaust allows compressed air leaving the tool to be directed through a suitable exhaust routing arrangement. This helps manage discharged airflow near the operator and workpiece. It does not remove grinding dust or replace a dedicated dust extraction system.

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

  A: Yes. The G1 Series supports light material removal, cleaning rough castings, deburring parts, and removing minor weld irregularities. Its high free speed can be useful for detailed grinding when paired with correctly sized and rated accessories. Material removal results depend on the abrasive, workpiece, and operating technique.

• Q: Is a 6 mm collet interchangeable with a 1/4-inch collet?

  A: No. A 6 mm collet and a 1/4-inch collet have different nominal diameters. Use accessories with shanks matching the installed collet rather than forcing an incorrectly sized shank into the tool. Confirm the correct replacement collet specification before changing configurations.
