For grinding, deburring, and surface preparation tasks that benefit from direct tool alignment and high abrasive speed, the Ingersoll Rand M2H180RG4 M2 Series Straight Grinder combines a 1 HP motor with 18,000 RPM free speed, a 1/4" collet, and rear exhaust. The straight configuration positions the tool and mounted abrasive accessory along the same working axis, making it suitable for accessible surfaces, openings, edges, and component features where a compact straight grinder layout matches the work geometry.
The Ingersoll Rand M2H180RG4 provides 18,000 RPM operation for compatible mounted abrasive accessories used in material removal, blending, and finishing processes. Unlike extended M2X configurations intended to provide additional reach, this M2 Series straight grinder uses a standard straight tool layout for work areas that do not require an extended body. 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.

- Pneumatic operation supports repeated grinding tasks when supplied with clean, regulated, and properly conditioned compressed air.
Applications:
- Metal fabrication — deburring edges, removing material, and preparing accessible surfaces with compatible mounted abrasives.
- Foundry and casting operations — cleaning cast surfaces, openings, and component features suited to a straight grinder configuration.
- Weld finishing — blending and cleaning compatible weld areas where direct tool alignment provides suitable access.
- Equipment maintenance — performing grinding and surface preparation on machinery, fabricated parts, and metal components.
- Production metalworking — supporting repeated abrasive operations where an 18,000 RPM straight grinder and 1/4-inch collet match the process requirements.
FAQs:
- Q: What size abrasive shank fits the Ingersoll Rand M2H180RG4?
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: What is the free speed of the M2H180RG4?
A: The grinder has a specified free speed of 18,000 RPM. Mounted abrasive accessories must be compatible with the 1/4-inch collet and rated for the actual operating speed and overhang conditions. - Q: How does the M2H180RG4 differ from the M2X180RG4?
A: Both supplied models are 1 HP grinders rated at 18,000 RPM with a 1/4-inch collet and rear exhaust. The M2H180RG4 uses a standard straight configuration, while the M2X180RG4 has an extended straight configuration for applications that require additional reach. - Q: What is the purpose of rear exhaust on this straight grinder?
A: Rear exhaust directs discharged air toward the back of the tool, helping keep the exhaust stream away from the immediate grinding area and operator interface. - 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 operating overhang, and a maximum permissible speed that meets the tool requirements. Follow the tool and abrasive manufacturer's inspection, mounting, and operating instructions.
