Ingersoll Rand M2X250RG4 Extended Straight Grinder | 1 HP | 25,000 RPM | 1/4" Collet | Rear Exhaust

For high-speed grinding and surface finishing operations that require additional reach into recessed or difficult-access work areas, the Ingersoll Rand M2X250RG4 Extended Straight Grinder combines a 1 HP motor with 25,000 RPM free speed, a 1/4" collet, and rear exhaust. The extended straight configuration helps operators reach internal features, confined surfaces, and work locations where a standard-length grinder may not provide suitable access, while the collet accepts compatible mounted abrasive accessories for grinding, deburring, blending, and surface preparation.

The Ingersoll Rand M2X250RG4 provides the fastest operating speed among the supplied M2X extended straight grinder configurations, making proper accessory selection especially important. Its 25,000 RPM speed supports high-speed abrasive action when paired with mounted accessories rated for the tool speed, shank size, dimensions, and operating overhang. Rear exhaust directs discharged air toward the back of the grinder, helping keep the exhaust stream away from the immediate abrasive contact area and operator interface.

FAQs:

• Q: What is the advantage of the extended configuration on the M2X250RG4?
  A: The extended tool body provides additional reach for recessed surfaces, internal features, and other work locations where a standard-length grinder may not provide suitable access.
• Q: What size abrasive shank fits the Ingersoll Rand M2X250RG4?
  A: The grinder is equipped with a 1/4-inch collet. Use only compatible mounted abrasive accessories with the correct shank diameter, suitable dimensions and overhang, and an operating speed rating appropriate for the tool.
• Q: How does the M2X250RG4 compare with the M2X200RG4?
  A: Both supplied models are 1 HP extended straight grinders with a 1/4-inch collet and rear exhaust. The M2X250RG4 operates at 25,000 RPM, while the M2X200RG4 operates at 20,000 RPM, making the M2X250RG4 the faster-running configuration.
• Q: Why is accessory overhang important when using this grinder?
  A: Mounted abrasive speed capability can decrease as the distance between the collet and abrasive head increases. Follow the abrasive manufacturer's maximum permissible speed guidance for the actual accessory dimensions and operating overhang.
• Q: What should be verified before installing a mounted abrasive accessory?
  A: Confirm the accessory has a compatible 1/4-inch shank, suitable dimensions and overhang for the application, and a maximum operating speed rating that meets the tool requirements. Follow the tool and abrasive manufacturer's inspection, mounting, and operating instructions.
